onScan.js is a simple framework agnostic JavaScript library, that produces scan-events whenever a connected barcode scanner or RFID reader scans a code or tag. Script callbacks are easy to hook to these events for seamless integration of hardware scanners into web applications.

This demo page lets you play around with the settings of onScan.js to find the best setup for a specific scanner. Just connect the scanner to your device and open this page in it's browser - than start scanning and watch the output in the console-box below.
