Add the ticket
Android
Google Wallet
An event ticket object through the Google Wallet API: event, venue and times live on the class, each pass carries holder, type, area and booking code. Smart Tap turned on.
What you get
Both tickets for a made-up holder, drawn from the same data as the real ones. The pictures change every hour.
How it would work
Book
A guest buys a ticket on the club’s site or at the office and gets a link, the pass lands in the wallet.
Tap
At the entrance the reader takes the ticket number from the phone and the server marks it as used.
Change
If the fair moves or a guest cancels, the pass is updated or voided in the wallet. No reprinting.
Try it with your own reader
Elatec TWN4 firmware
The keyboard firmware for an Elatec TWN4 MultiTech reads this ticket too: hold it to the reader and it types the ID, followed by Enter. It is handed out on request only, because the image carries its key in plain form.
For an ACS WalletMate II there is a key package instead: it stores the demo key in the reader’s Apple slot, and the reader decrypts the pass itself. Both come through the same request.
