About

Proof-of-concept barcode scanner using the native BarcodeDetector API, ZBar-wasm, and ZXing-js fallback engines. Integrates with EventData via OAuth 2.0 PKCE. Full attendee database synced to IndexedDB for offline-first scanning.

Barcode Parsing

If barcodes contain extra characters around the record number, enter a regex to strip them first. Leave blank for auto-detection.

Strip regex (e.g. ^EVT-)

If set, applied before auto-detection. Matched portion is removed.
