Built with Passmint

Punchline is a made-up café. Everything that happens to the pass is real, and runs on Passmint: one API for Apple and Google Wallet passes.

Issue: Scanning the code makes one passes.create() call. Passmint signs the pass and hosts the add-to-wallet page.
Update: Each punch is one passes.update(). Passmint re-signs it, swaps the strip art and pushes it to the phone.
Hear back: Webhooks report when the pass lands in a wallet and when the phone picks up each update.
