The new tesco QR codes are cool
As Chris explains in this video, Tesco are clearly trialling a new QR code which can replace traditional barcodes and also contain info for stock management like the expiry date.
The cool thing here is thay they are also scannable by customers which open the product’s URL on thetesco website. They do this by encoding this data as a URL which includes the GTIN (from traditional barcodes), batch number and expiry date like this:
https://tesco.com/<GTIN>/<betch number>?17=<expiry date>Here’s an example:
https://tesco.com/01/05051277937280/10/101150200?17=260505Their checkouts and other readers can extract the bits they need and when a customer scans it this URL just redirects to the correct product URL.
