The tool accepts the product numbers printed under retail barcodes, all of which are GTINs (Global Trade Item Numbers) defined by GS1:
A UPC is a GTIN-13 with a leading zero, so the same product can be found by either number.
Tap Scan with camera, allow camera access, and point your phone at the barcode. The number is detected automatically and the product is looked up. Scanning runs entirely in your browser – no app to install. The scanner is built with [STRICH](https://strich.io/), our barcode scanning SDK for web apps.
