Create a digital stamp card.
Stamp cards make repeat-visit progress familiar, immediate, and easy to follow.

Create the card
Keep the earning rule and completed-card benefit obvious.
A digital stamp card should feel as immediate as the familiar paper version. Use one easy-to-recognize action per stamp and a completion reward that customers can remember without checking the rules.
Choose the action
Decide what earns one stamp.
Set the target
Pick a motivating number of stamps.
Choose the reward
Make the completed-card benefit clear.
Run the card consistently
Use the same earning and completion flow at every visit.
Train staff, set practical frequency rules, and review how many members start, progress through, and complete the card.
Pay attention to cards that are started but rarely completed. The target may be too distant, the earning event may happen too infrequently, or staff may not be applying stamps consistently.
