They receive the promo card
A potential regular walks past one of your branded promo cards — left on a counter, dropped in a take-out bag, handed out at an event. They scan it. A "Free coffee on us — redeem within 72 hours" pass installs in their wallet in five seconds. No app, no account, no friction. Your logo lives on the pass. Your colors. Your header. When their phone vibrates with a notification, they see YOUR brand — not ours.
Endowed Progress
Head-start stamps already on the card (Nunes & Drèze 2006: 79% more completions).
Loss Aversion
The free thing is theirs the moment it’s installed; losing it feels like loss.
Reciprocity
You gave first; they want to give back.
Urgency
72 hours to redeem drives action (up to 332% lift on time-limited offers per Invesp).
