Frequently Asked Questions
Clear technical answers to help you design, test, and deploy with confidence.
Do I need to install an app to scan QR codes, barcodes, or NFC tags?
No. Everything runs directly inside your web browser. You can activate your laptop or phone camera to scan live codes, upload a photo or screenshot from your device, or tap physical smart tags via the Web NFC API on supported Android devices.
Which barcode formats does this scanner support?
Our scanner supports standard 2D QR codes and all major 1D retail and logistics linear barcodes, including Code 128, EAN-13, EAN-8, UPC-A, UPC-E, Code 39, and ITF-14.
Are my camera feed or scanned data uploaded to a server?
Never. All video frames, image decoding, and NFC payload parsing happen strictly inside your browser's local memory. No images, video streams, or decoded data are ever sent to any remote server or stored in the cloud.
Can I scan barcodes and QR codes from saved photos or screenshots?
Yes. Simply click 'Upload Image' or drag any image file onto the scanner. The optical decoding engine will analyze the image and extract the payload in milliseconds.
