A stamp card paid in advance on the scanner
Deduct stamps
The four quick tiles read -1, -2, -3, -4. Tap one to remove that many stamps (the customer is spending what they prepaid). The custom stepper is subtract-only.Recharge the card
When the card runs down to 0, the Charge card button becomes active. Tap it to reload the card to full, so you can sell the customer another prepaid round. It stays greyed out until the card is fully used.For a normal (earn-as-you-go) stamp card, see Stamp cards on the scanner.
