A loyalty program for car washes
This is the trade the loyalty-card research was done in. Sell a book of washes up front, or run a stamp card — scanned at the bay, in the driver’s phone, not the glovebox.

A WORKED EXAMPLE
Book of ten washes
Example figures, not research — put your own in the calculator below. What matters is the shape: a block priced a little under the sum of its parts, paid for on day one.

$15017% off, paid up frontThe evidence comes from your trade
The field experiment behind every loyalty-card claim was run at a car wash: 300 cards, eight washes either way, and completion rose from 19% to 34% when the card started part-way. You are the case study.
Volume without a queue
Scanning a code is faster than finding a card, punching it and handing it back. At a busy bay that difference is the queue.
Nothing lives in the car
A glovebox card is only present when the car is. A wallet pass is on the phone of whoever is driving.
YOUR SIDE OF IT
One screen. Who is owed what.
Every client, every remaining wash, every package you have sold. Search by name, phone number, pet or vehicle when there is no code to scan — for the client who turned up without their phone.
