What is Wallet pass?
A wallet pass is a digital card stored in Apple Wallet or Google Wallet on a phone, the same place as boarding passes and tickets. It needs no app and can update after it has been saved.
Bhookly issues each restaurant's stamp card as a wallet pass in the restaurant's branding. A guest joins by scanning a counter QR and entering a name and phone number, and the card updates after each visit. A wallet broadcast pushes one short message onto every saved card, with no per-message cost.
