Google Wallet passes.

Let members save loyalty cards, stamp cards, vouchers, and prepaid passes to Google Wallet for quick access.

Configure Google Wallet once for the whole installation: a Google Cloud project, an issuer account, and the credentials.

Turn Google Wallet on per card, and see how each pass type appears in a member's wallet.

Save a loyalty card, stamp card, or voucher to Google Wallet, view it, and see how the pass changes as you earn.

Test the Google Wallet flow, fix a button that does not appear, and understand the local-development limits.
