The counter scan problem
The account page originally offered a QR code only. Field reports told another story: many stores run one-dimensional barcode scanners, so staff typed the card number by hand while the queue grew. A classic case of right screen, wrong context: the design looked complete in the office and failed at the counter, under real lighting, distance and scanner hardware.
Add the barcode, then let it grow
The redesign took two steps. First, put the one-dimensional barcode straight into the member card block next to the card number, so most scans just work. Second, handle the scans that do not: an expand control opens a full-screen version rotated ninety degrees, thick bars, high contrast, screen brightness pushed up, readable from farther away. The design note fits in one line: the real user of a redemption screen is the scanner gun. Make it comfortable for the gun first, and the human follows.
