Why Enterprises Choose VeryUtils JavaScript SDK Over Open-Source Alternatives

Meta Description:

Frustrated with clunky barcode scanning tools? Discover why developers are ditching open-source scanners for the fast, secure, and browser-ready VeryUtils JavaScript SDK.

Every Dev Team Has That One Barcode Nightmare...

You've been there.

The deadline's close.

The CTO wants real-time barcode scanning in the web app, and you've spent days testing open-source libraries that promise a lot but fall flat fast.

Why Enterprises Choose VeryUtils JavaScript SDK Over Open-Source Alternatives

One project I worked on had a retail client who needed live barcode scanning in their inventory appno native apps, just browsers.

Sounds simple, right?

We tried several open-source solutions first. Zxing was heavy and clunky on mobile. Quagga.js? Barely read QR codes in poor lighting. None of them felt production-ready.

Then we found VeryUtils JavaScript Barcode Scanner SDK.

That project? Delivered ahead of schedule.

No weird mobile bugs. No decoding failures. And no customer complaints.

Let me walk you through why I've kept it in my toolkit ever since.

Why VeryUtils JS Barcode Scanner Works Better Than Open-Source

First Impressions: What You Actually Get

VeryUtils built this SDK with enterprise devs in mind, and it shows.

We're talking about scanning directly in the browser, no downloads, no plugins, no fluff.

Just fast, reliable scanning from camera or imageacross devices.

From mobile to desktops, it works.

Use case?

  • Inventory apps

  • Warehouse scanners

  • POS systems

  • Event ticketing

  • Web check-in systems

  • Digital forms and logistics portals

  • Progressive Web Apps (offline barcode scanning? Yes.)

It supports all the major 1D, 2D, and postal barcode formatsfrom Code 128 and QR Codes to PDF417 and USPS IMB.

That's already miles ahead of most open-source options.

What Makes This SDK a No-Brainer

1. Scan Speed That's Actually Enterprise Grade

Here's the real-world test.

Try scanning from a live video stream in a busy, fluorescent-lit warehouse.

We needed to pull in 400+ barcodes per session.

Open-source options lagged and failed mid-way.
VeryUtils? It scanned over 500 barcodes per minute with smooth continuity.

In our setup, even damaged, low-light, and poorly printed barcodes got recognised.

That's WebAssembly power under the hood.

And it's insane how lightweight it is for what it does.

2. Built-In User Feedback Tools

Ever try explaining to users how to hold a barcode right in front of a camera?

With VeryUtils, that's solved.

  • Visual guidance overlays on the camera

  • Audio cues for successful scans

  • Optional haptic feedback on mobile

These details make the app feel polished, and users don't need training.

Open-source libraries just don't think about the UX layer.

You end up building all that from scratch.

Time you don't have.

3. Zero Setup. All Browser. All Devices.

Here's the magic line from the CTO:

"Can it work in Safari on iPhones too?"

Usually, that's where open-source dies.

Browser compatibility becomes a nightmare.

But this SDK?

It just works across Safari, Chrome, Edge, Firefoxmobile or desktop.

Just add the JS script, your license key, and you're live.

No installation. No app store approval. No broken camera access.

And if you're building a PWA, you're in luck.

The SDK supports offline scanning with full barcode decoding.

Total game-changer for logistics and fieldwork.

A Real Story: Retail Deployment in 72 Hours

One of our recent clients needed a barcode scanning module fast.

Their React-based internal app was for tracking store shipments.

No native apps.

No time for training.

I integrated the VeryUtils SDK over a weekend.

Steps?

  • Added the JS script in the HTML header

  • Set the license key

  • Used the decodeFromVideoDevice() method

  • Customised user cues (sound + overlay)

  • Deployed to staging Monday morning

It was live by Wednesday.

Compared to our previous open-source project that took two weeks (and still didn't work on some Android phones), this felt like a shortcut I didn't know I was allowed to take.

Key Features That Changed the Game

  • Batch Scanning: Scanned multiple barcodes in the same frame. Useful in warehouse pallets.

  • OCR + Camera Enhancements: Picked up codes from crinkled labels that others missed.

  • High Accuracy: The error rate was practically zero, even in variable lighting.

  • Security First: No data was sent off-device. Completely browser-contained.

  • Customisation: We added our brand overlay and feedback sounds in under an hour.

Who Should Use This?

If you're in one of these roles, this SDK will save you time and grey hairs:

  • Full-stack developers building internal tools

  • Product owners needing fast deployments

  • Logistics and warehouse teams wanting browser tools

  • Retailers wanting scan-to-cart apps

  • Event managers for digital ticket scanning

  • Government forms and registration portals

Basically, anyone tired of patching together half-baked scanning solutions.

But What About Open Source?

Yeah, I get it.

Open source is free.

But free isn't free if it eats your dev time.

Here's what I learned:

Criteria Open Source VeryUtils SDK
Mobile Compatibility Spotty Solid across iOS/Android
Scan Accuracy OK-ish Enterprise level
UX Tools None Built-in
Batch Scanning Limited Full support
Speed Mid 20+ scans/sec
Support Forums, maybe Email + documentation
Setup Complex Plug-and-play

Final Thoughts: Worth Every Dollar

Let's be realtime is money.

The cost of a buggy, unstable barcode scanner?

Support tickets, frustrated users, lost sales, delays.

The VeryUtils JavaScript Barcode Scanner SDK didn't just save us time.

It made us look like heroes to the client.

So yeah, I'd absolutely recommend this to any dev team building barcode features into web or mobile apps.

Don't waste days wrestling with open-source.

Just get this SDK and move forward.

JavaScript Barcode Scanner SDK for Scanning Tax Forms, Legal Files, and Government IDs

Posted on

JavaScript Barcode Scanner SDK for Scanning Tax Forms, Legal Files, and Government IDs

Meta Description:

Scan government IDs, tax forms, and legal documents right in your browser with the VeryUtils JavaScript Barcode Scanner SDK for Web and Mobile.

Every tax season, I dread one thingbarcode chaos.

You know the drill.

JavaScript Barcode Scanner SDK for Scanning Tax Forms, Legal Files, and Government IDs

Stacks of scanned tax forms, each with a barcode, and you're squinting at a screen trying to make out blurry digits. Same story with legal documentscourt filings, ID verifications, shipping labels for case files. At one point, I was spending hours manually decoding barcodes on scanned forms. My frustration peaked when a misread barcode led to a processing delay for a legal request. That delay cost a client.

I knew there had to be a better way.

So I went huntingand that's how I found VeryUtils JavaScript Barcode Scanner SDK for Web and Mobile Apps.

The tool that changed everything

I stumbled on the VeryUtils JavaScript Barcode Scanner SDK while looking for a browser-based scanning solution.

No installations. No downloads.

Just JavaScript.

One script and boomyour camera becomes a pro-level scanner that works across mobile and desktop browsers.

I couldn't believe how fast it decoded barcodes. Not just clean ones eitherdamaged, wrinkled, badly lit codes too. It handled them like a champ.

And the best part? It works inside the browser. No apps. No friction for end-users.

Here's how I put it to work.

Why this SDK works where others don't

I wanted: No installation, no hassle

Most barcode tools out there want you to install software, or worse, build an app from scratch.

VeryUtils nailed it with zero-setup.

Just add a few lines of JS, drop in your license key, and you're off. Your users just open the page and scan. It's as clean as it gets.

Real-time scanning from video streams

I'm talking live barcode detection straight from a laptop or phone camera.

I tried their demo here and it blew me away.

No lag. Instant decoding. Even when scanning dozens of barcodes back-to-back, it never broke a sweat.

One client used it to process over 10,000 tax documents in a weekflawlessly.

Who this is for (and how they're using it)

Government Offices

Think of DMV branches, tax agencies, immigration offices. They're always processing piles of ID cards, forms, and scanned records. This SDK makes it painless to scan those documents directly from browser-based portals. No extra hardware. No downloads. Just open and scan.

Legal Teams

Whether it's managing court exhibits or verifying legal IDs on scanned images, this tool removes the friction. It works even when the barcode is worn out or partially missing.

HR Departments & KYC Workflows

Need to verify someone's government ID during onboarding? Build it right into your web-based HR platform. I worked with a startup that uses this SDK to validate hundreds of employee IDs every week during remote onboarding.

Developers building scanning tools

If you're building a web portal and need barcode support, this SDK gives you power features without the 10,000-line headache. The API is friendly. The learning curve is tiny. You'll be scanning barcodes in an afternoon.

Three killer features that stood out for me

1. Fast, accurate, and works under pressure

I scanned barcodes from documents with:

  • Low lighting

  • Wrinkled edges

  • Missing corners

  • Reflections from overhead lights

Still nailed them.

The SDK supports 20 barcodes per second, over 500 per minute if you batch process. That's wild.

2. Offline support (yes, even offline)

This thing is PWA-ready, which means it works even without an internet connection. You can set up scanning workflows that run in the field, in courtrooms, in warehouse basementsanywhere.

One government client I worked with runs it in a restricted internal network. No external cloud processing. The scanner just works.

3. Broad barcode format support

I'm not just talking QR codes.

This SDK supports everything:

  • PDF417 (used on driver's licenses)

  • Code 128

  • GS1 DataBar

  • Aztec

  • USPS IMB

  • DataMatrix

  • Japan Post and Royal Mail formats

I've scanned barcodes from:

  • IRS 1040 forms

  • Legal summons with QR codes

  • Driver's licences from 3 states

  • Court-submitted evidence labels

Every format? Read perfectly.

How I use it in the real world

I built a small internal tool for our firm.

All it does is open your camera, scan the barcode, and paste the decoded text into a case tracking system. We use it to verify incoming legal forms.

Takes 5 seconds per doc, down from 30.

And we do it all in the browser, across Windows laptops and iPads.

Our clients submit scanned forms via PDF. We decode them using the SDK right inside the browser. No more emailing IT for access to barcode readers or struggling with outdated scanners.

Compared to everything else I tried...

Other solutions I used:

  • Required a native app

  • Couldn't handle wrinkled barcodes

  • Choked on low-res scanned images

  • Had license limits that made scaling painful

VeryUtils?

  • Browser-based

  • Fast, accurate, and scales without a sweat

  • Simple license setup

  • Works like magic across platforms

This is what it solved for me

  • Stopped manually checking barcodes on tax forms and ID cards

  • Cut legal form intake time by 70%

  • Avoided delays from unreadable barcode submissions

  • Gave clients a way to self-scan documents securely

  • Reduced hardware dependencies (we no longer need barcode scanners)

I've recommended this to three colleagues already.

If you're dealing with government forms, legal files, or any document-heavy workflow that relies on barcodes, use this.

Comparing Free vs Paid JavaScript Barcode Scanning Libraries for Enterprise Use

Comparing Free vs Paid JavaScript Barcode Scanning Libraries for Enterprise Use

Meta Description

Stop wasting hours with free barcode libraries that can't handle real-world demand. Here's what I learned using VeryUtils for enterprise-grade scanning.

Comparing Free vs Paid JavaScript Barcode Scanning Libraries for Enterprise Use

Every dev's been here

You find a free JavaScript barcode scanning library on GitHub. It looks promising. You clone the repo, wire it into your project, and at first it works. Sort of.

Then things go sideways.

You try scanning a crumpled QR code from a label on a shipping box. Nothing. You test in low light. The scanner freezes. You throw it into an enterprise app for live use and it crashes under load.

Been there? I have. And I got tired of pretending free tools could do pro-level work.

That's how I ended up using VeryUtils JavaScript Barcode Scanner SDK. Let me break down what happened when I stopped messing around with free barcode libraries and switched to a paid one that just worked every time.

Why I ditched free barcode scanning libraries for good

I've tried a lot of them. You know the names QuaggaJS, jsQR, Dynamsoft's free tier. I wanted something that could:

  • Scan from live camera reliably

  • Support a wide range of barcode formats

  • Run offline or on poor networks

  • Deliver accurate reads even with poor lighting, glare, or damaged labels

Here's the thing: most free libraries nail one of those. Rarely more. But in real-world enterprise use warehouses, logistics, retail, healthcare you don't get ideal conditions.

You get scratched codes. Poor lighting. Shaky hands. 200 scans per minute. Users on 3G.

That's where VeryUtils Barcode Scanner SDK stepped up.

What is the VeryUtils JavaScript Barcode Scanner SDK?

It's a WebAssembly-powered JavaScript SDK that turns your browser into an industrial-strength barcode scanner.

No installs. No native app needed.

Just JavaScript and a camera and boom you're scanning like a pro.

And it works on:

  • Web apps

  • Mobile browsers

  • PWAs

  • Internal enterprise portals

I was able to integrate it into an internal inventory management system in under 30 minutes. No native builds. No Cordova. No Flutter headaches.

Who should care about this SDK?

If you're a developer or product manager working on:

  • Retail POS or inventory systems

  • Warehouse and logistics tracking

  • Healthcare scanning in hospitals

  • Field service tools

  • Delivery apps

  • Internal dashboards for ERP/CRM

This SDK will probably save your team weeks of dev time and countless hours in debugging.

What makes VeryUtils Barcode SDK actually usable in the real world?

Let's break it down.

Scan accuracy that doesn't quit

This was the first "wow" moment.

We scanned over 300 real-world barcodes torn shipping labels, printed QR codes behind plastic covers, faded receipts.

It got them all.

While the free tools struggled or flat-out failed, VeryUtils decoded them almost instantly even when the codes were off-angle, smudged, or had parts missing.

It supports over 50 barcode types including:

  • 1D barcodes like Code 128, UPC, EAN

  • 2D codes like QR, DataMatrix, PDF417

  • Postal barcodes like USPS IMB and Australia Post

Insane speed 500+ scans per minute

This isn't theoretical.

In a live test with a webcam stream and rotating barcodes, I pushed over 500 scans per minute and the SDK didn't flinch.

The detection loop is blazingly fast, even when decoding from video streams.

If you're building apps where speed = money (retail checkouts, bulk inventory scanning, etc.), this SDK pays for itself in time saved.

Smart UX features built-in

Free libraries don't care about the user experience. This one does.

It comes with:

  • Haptic feedback (vibration on success)

  • Audio cues (customisable success sounds)

  • Visual guides for framing barcodes

These small things massively improve the scan flow especially for non-tech users in a warehouse or on a delivery route.

Works in low-connectivity environments

This SDK supports Progressive Web Apps (PWAs). That means:

  • It works offline

  • Loads from cache

  • Doesn't depend on a stable network

Perfect for field workers or retail stores with dodgy Wi-Fi.

My personal setup: From pain to productivity

Here's how I integrated it into a mobile-first web app for a warehouse client:

  1. Added the SDK script via CDN

  2. Set the license key (you get this after purchasing)

  3. Wrote 10 lines of JS to hook up the video stream

  4. Deployed it behind a login for internal staff

We went from concept to working prototype in a single afternoon.

The feedback?

Warehouse workers loved it. It was faster than their legacy scanner guns and ran on cheap Android phones.

Free vs Paid Barcode Scanners It's not even close

Free tools:

  • Limited barcode support

  • Slower performance

  • Poor accuracy in low light or glare

  • No user feedback features

  • No offline support

VeryUtils Barcode Scanner SDK:

  • 500+ barcodes per minute

  • 50+ barcode types

  • Works offline (PWA-ready)

  • Enterprise-grade performance

  • Customisable user experience

If you're building throwaway hobby projects sure, free works.

But for enterprise use cases, free tools cost more in hidden dev time and bugs.

With VeryUtils, I got pro-level performance out of the box.

Final verdict: Worth every penny

I don't say this lightly most paid libraries are just bloated versions of free tools.

But VeryUtils actually delivers.

It gave me reliable barcode scanning with minimal setup, full offline capability, and enough format support to handle anything from USPS to Aztec codes.

I'd highly recommend this to anyone building serious barcode features into web or mobile apps.

Turn Any Web App Into a Barcode Scanning System Without Camera Hardware Upgrades

Meta Description:

Turn your browser into a barcode scannerno app installs or camera upgrades requiredwith the VeryUtils JavaScript Barcode Scanner SDK.

Turn Any Web App Into a Barcode Scanning System Without Camera Hardware Upgrades

Every warehouse audit used to feel like a warzone.

Picture this: we're mid-inventory, the scanners are dying, and some genius left the spare handhelds at the other facility.

To make things worse, half the mobile devices in the room couldn't run our inventory app because of outdated OS versions.

So there I am, staring at a stack of boxes, knowing every one of them has to be scanned before the end of the shift.

What saved us?

A browser.

Seriously. A standard browser, some duct-taped tablets, and the VeryUtils JavaScript Barcode Scanner SDK.

How I Found It (and Why It Was a Game-Changer)

Let me back up.

I stumbled on VeryUtils JavaScript Barcode Scanner SDK while looking for a browser-based barcode reader. We had zero time for hardware upgrades and even less budget to hire a team of devs to build a custom scanner.

All I needed was:

  • Something fast.

  • Something dead simple to deploy.

  • Something that actually worked on older devices with just a camera and a browser.

And this SDK checked all the boxes.

With a single script, our web app turned into a high-speed barcode reader that handled live scanning from video streams with zero app installs.

What It Does (In Real English)

It turns any web or mobile app into a full-on barcode scanning systemstraight from the camera.

There's no need to buy new devices, install external apps, or deal with OS compatibility nightmares.

Just open your browser. That's it.

It works across:

  • Mobile browsers (Android/iOS)

  • Desktop/laptop cameras

  • Internal networks and public sites

  • Online and offline (yep, it works in low-connectivity zones too)

The SDK even handles the barcode decoding in real-time, straight from video feeds or image files.

And the kicker? It's insanely fast.

Let's Talk Speed (And Accuracy)

Most barcode scanners I've used in the past were either:

  1. Slow as hell

  2. Unreliable in poor lighting

  3. Useless with damaged labels

This SDK?

It hits 500+ barcodes per minute without choking.

Accuracy? Close to 99%even with:

  • Wrinkled barcodes

  • Glared labels

  • Damaged QR codes

  • Missing borders

The secret sauce? WebAssembly and OCR-enhanced detection.

Yes, it's got OCR built inso it doesn't just read barcodes, it recognises characters too, even in rough conditions.

3 Features That Blew Me Away

1. Multi-Barcode Scanning in One Go

Scanning barcodes one by one is soul-crushing.

This SDK lets you batch scan like a machine. I pointed the camera at a shipping label sheet with 8 barcodesboom, all recognised in under 2 seconds.

No need to pause or refocus.

It just does it.

2. Works Offline (Seriously)

We tested it in a rural fulfilment centre with terrible Wi-Fi.

Thanks to PWA (Progressive Web App) support, the SDK still ran in the browser like nothing happened. No spinning wheels. No network errors.

Just barcode detection that kept on going.

3. Zero Setup for the End User

Here's the line that sold me:

"No app installs. No camera permissions dialog loops. No training."

Once deployed, the team opened a browser link and were scanning within seconds.

No IT tickets. No update requests.

If they could click, they could scan.

Where It Shines (Real-World Use Cases)

Warehouses & Logistics

The SDK lets warehouse staff use existing tablets or laptops to scan incoming/outgoing goods without investing in rugged scanners.
Speed? Check. Cost savings? Massive.

Retail & POS

It turns your store's POS web app into a live scanner. Cashiers don't need new hardwarejust a phone or tablet camera.

Healthcare

Hospitals can scan patient wristbands or medication barcodes directly via internal browser apps, maintaining hygiene standards with minimal touchpoints.

Libraries & Archives

Need to scan hundreds of book barcodes for cataloguing? Open the browser, point the camera, and go. No drivers, no licenses, no friction.

Event Check-In Systems

Run your check-in process using just mobile web appsno QR reader rentals, no custom apps to download for guests.

Who Should Use This?

You'll love this SDK if you're:

  • A developer building web apps for logistics, retail, or operations

  • Running any kind of mobile-first inventory system

  • Managing check-in/out processes at events

  • Handling asset tracking with minimal tech budget

  • Sick of writing workarounds for app store permissions

Basically, if your users have browsers and cameras, this thing delivers.

Why It Beats Other Barcode Scanners

Let's be real: most barcode libraries are clunky.

They need native apps, extra downloads, constant permission prompts, or just don't work well on budget devices.

VeryUtils JavaScript Barcode Scanner SDK:

  • Runs entirely in the browser (JS + WebAssembly)

  • Doesn't eat your bandwidth

  • Offers secure, private processing

  • Updates automatically via script reference

  • Supports every major barcode typefrom UPC, EAN, Code 128 to PDF417, DataMatrix, and QR codes.

You're not locked into one format or device.

Why Choose a JavaScript Barcode Scanner SDK for Web Apps with Offline Scanning Support

Meta Description:

Need barcode scanning in your browser? Here's how I added offline barcode scanning to my web app with VeryUtils JavaScript Barcode Scanner SDK.

Why Choose a JavaScript Barcode Scanner SDK for Web Apps with Offline Scanning Support

Every time a delivery came in, the process felt prehistoric.

We'd unpack boxes, grab a clipboard, check off SKUs, type the same product codes into a spreadsheet, and pray someone didn't mistype a number. Every mistake cost time, sometimes money.

I remember thinking, Why can't this just be scanned like in stores? Why does a web app feel so limited when it comes to simple tasks like barcode scanning?

Turns out, it didn't need to be that way. I found a fix that didn't involve buying proprietary hardware or shipping everyone a dedicated scanning app. All it took was a JavaScript barcode scanner that works in the browsereven offline.

Enter VeryUtils JavaScript Barcode Scanner SDK

If you're building a web or mobile app and you need to scan barcodes or QR codesthis SDK is a game changer.

No browser plugins.

No native app development.

No bloated libraries or flaky third-party APIs.

Just one fast, powerful JavaScript SDK that plugs right into your frontend and makes barcode scanning a first-class feature, even when the network is unreliable.

Here's how I used itand why I'd never go back.

What Is It?

VeryUtils JavaScript Barcode Scanner SDK for Web and Mobile Apps is exactly what it sounds like: a pure JavaScript library that turns any webcam-equipped device (laptop, tablet, phone) into a fast, accurate barcode scanner. You can use it with images, live video, or even offline using PWA support.

I got it up and running in under 20 minutes. Zero back-end setup. Just import the script, drop in a few lines of JavaScript, and boombarcode magic.

Who's This For?

If you're any of the following, this SDK was made with you in mind:

  • Developers building internal tools or client dashboards

  • Retail managers who want in-browser product verification

  • Warehouse teams that need lightweight barcode scanning

  • Inventory platforms trying to support mobile workflows

  • Event organisers scanning tickets or registrations

  • Healthcare or pharma tracking meds or lab samples

Basically, anyone sick of jumping between hardware scanners and spreadsheets.

What It Actually Does (and Does Well)

1. Real-Time Barcode Scanning from Webcam or Image

You can scan over 500 barcodes per minute using live video feeds. This isn't a janky image upload flowit's the real deal. I tested it using both front and back cameras on a few phones and even a crusty old laptop webcam. Worked great across the board.

2. Works Offline via PWA Support

This one was huge for us. Our warehouse Wi-Fi is patchy at best. With offline support baked in, users could scan products and queue up the results locally until they reconnected. No more "connection error" popups or lost entries.

3. Scans Damaged, Faded, or Crumpled Codes

Not every label comes out clean from the printer. Some are scratched. Some get bent. Some are half-smudged from water damage. The SDK handled them like a pro. It uses advanced OCR and camera-enhancing tech behind the scenes to clean up the input before decoding.

4. Multi-Barcode Scanning at Once

I didn't expect this to be so helpful. But when we had to scan boxes with multiple codesone for the batch, one for the item, one for the warehouse locationthis saved tons of time. It picked up all three in one go.

5. Tons of Barcode Formats Supported

From QR codes to Code 128, PDF417, Data Matrix, even obscure ones like Royal Mail or Pharmacodethis SDK supports over 40+ barcode types.

It's not limited to the basics. You can throw all kinds of industry-specific codes at it and it'll likely recognise them.

Real-World Use Case: Inventory Check-In for Web-Based ERP

We use a custom ERP web app internally.

Instead of building out a mobile app (ugh, too much overhead), we just added the JavaScript Barcode Scanner SDK right into our check-in page.

Here's what we did:

  • Employees use their phone's camera (no app download needed).

  • They scan the barcode on incoming stock boxes.

  • The data fills in automatically in the form fields.

  • If the network is down, the scan still goes through and syncs later.

This one addition took our check-in time from 2 minutes per item to about 15 seconds.

No exaggeration.

Comparisons: Why Not Use a Native App or Open Source?

Native apps?

Costly. Slow to develop. Need iOS/Android teams. Maintenance nightmare.

Open-source JS libraries?

I tried a few. Most of them choke on non-ideal barcodes (blurry, bent, dim light). And batch scanning? Forget about it.

VeryUtils has WebAssembly speed behind it, and it's updated regularly. That combo gives it a serious edge.

Key Wins for Me

  • Didn't have to write any back-end code

  • Setup in 20 minutes

  • Runs offline via PWA

  • Worked great on low-end Android phones

  • 99%+ accuracy in real-world scanning

FAQs

Can I use the SDK in a React or Vue project?

Yes, the SDK is pure JavaScript and works well in any frontend framework. You can wrap it in a component or use it in vanilla JS apps.

Does it work on iOS and Android browsers?

Absolutely. As long as the browser can access the camera (Chrome, Safari, etc.), it works seamlessly.

What about security? Does data get uploaded?

No data is sent anywhere. Everything runs locally in the browser. That's a big win for industries with strict compliance requirements.

Can I scan multiple barcodes at once?

Yes. The SDK supports batch scanning and can read several barcodes in a single camera frame.

What barcode formats are supported?

Over 40 formatsincluding QR, Data Matrix, PDF417, Code 128, EAN-13, UPC-A, Royal Mail, GS1, and more.
