└────────────────────────────────────────────────────────────────────────┘- •Frictionless Acquisition: The customer scans a tabletop or counter QR code. Their mobile browser loads a high-converting landing page, and with a single tap, the pass is saved to Apple Wallet or Google Wallet with zero registration forms or passwords.
- •First Stamp Gratification: The barista or cashier scans the pass, awarding the first stamp. The phone vibrates with an instant lockscreen confirmation.
- •Mid-Progress Nudge: When the customer reaches 4 out of 8 stamps, an automated location or time-based reminder encourages their next visit.
- •Imminent Reward Urgency: At 7 out of 8 stamps, a high-urgency lockscreen message alerts the customer that their reward is ready.
- •Seamless Reset & Status Upgrade: Upon redeeming the 8th stamp for a free item, the card resets to 0 and upgrades the visual tier (e.g., Gold VIP border).
2. Anti-Fraud & Security Invariants
- Dynamic Encrypted Barcodes: Prevent customers from photographing or sharing physical punch cards.
- Authenticated Cloud Webhooks: Each stamp requires an authenticated POS API call.
- Velocity Rate Limits: Prevent staff abuse by capping stamp awards to a maximum frequency (e.g., 1 stamp per 4 hours per customer).
