I’m curious what it does that Claude or Codex can’t. Fundamentally it’s just producing an image with a QR code on it, right?
In some cases, yes, but I've used a digital ticketing system (Ticketmaster) where the barcode changes about every 20 seconds. Short of reproducing that barcode generation algorithm, Claude or Codex wouldn't help.

It integrates with Apple's pass system and the app they have to let users collect their cards, passes and tickets in one place (whatever it's called), it's not about creating a PNG.
