Design the card
Pick colours, one of 16 stamp icons, from 2 to 20 stamps and up to five rewards. The preview is the card your customers will see.
Stamp per visit or per round, from the bartender's phone. Apple and Google Wallet.
A bar regular comes once or twice a week, mostly in the evening, often with the same friends, and orders more than once a night.
Per visit is the simplest rule: one stamp a night, whatever the bill.
Bartenders have a queue and wet hands.
Keep rewards to things that cost you little and bring the guest back on another night: a plate of snacks for the table, a pint, a glass of house wine.
