How to set up a car wash loyalty program with QR codes

Why paper stamp cards fail at a car wash

• Water and soap. Cards get soaked, ink smears, and stamps become unreadable.
• Lost in the car. Cards end up under seats or thrown away during a cleanout.
• Easy to fake. A borrowed stamp or a photocopied card is hard for staff to spot.
• No data. You can't see who your regulars are or who stopped coming.

Why a QR loyalty card works better

With a digital card the stamps live on the customer's phone, so there's nothing to get wet or lose. The customer scans your store QR once to join, and your staff adds a stamp after each wash. Every stamp is checked on the server, so stamps can't be copied or added twice.

Reward ideas that work for car washes

• Every 5th wash free — easy to understand and easy to reach.
• Milestone rewards — free tire shine at 3 washes, free wash at 6, free interior clean at 10.
• Upgrade rewards — a free wax or premium package instead of a basic wash.
• Limited-time promos — double stamps during the rainy season or slow weekdays.

Setting it up in 4 steps

1. Create your business and choose your reward (for example, 5 stamps = 1 free wash).
2. Print your store QR and place it at the cashier or waiting area.
3. Customers scan it with their phone camera so no app download needed.
4. After each wash, staff scans the customer's QR and taps to add a stamp.
