Wallet passes vs an app vs paper
Three ways to run a loyalty program, each genuinely better than the others at something. We build one of them, so read the last section first if you want the part where we argue against ourselves.
Paper punch cards
Still the fastest to start and the cheapest to try. No account, no phone, no signal. A rubber stamp works during a power cut.
What you give up is everything after the stamp. You cannot tell how many cards are in circulation, who has gone quiet, or whether the program is doing anything. You cannot reach a customer between visits. And they are trivially forged — a €4 stamp from any stationers reproduces most café cards.
If you run one small shop, have no intention of measuring anything, and simply want to reward regulars, paper is a perfectly rational choice. It stops being one the moment you want to know whether it works.
A branded app
The most capable option, and the hardest to fill. An app can do anything: ordering, payments, tiers, push, personalisation.
The problem is the install. Asking someone at a counter to go to an app store, search, download 40 MB and create an account is a lot of friction for a free coffee, and most people decline. A small business typically converts a low single-digit percentage of customers into app installs, which means the program never reaches the people it was for.
Apps make sense when the app does more than loyalty — if people are ordering ahead or paying through it, loyalty is a feature and the install is already justified.
Wallet passes
A middle path: the card lives in Apple Wallet or Google Wallet, apps already on the phone. There is nothing to download and no account to create, so joining takes seconds at the counter rather than minutes.
Because the pass is in the wallet, it updates itself and can carry a message to the lock screen — a marketing channel that needs no phone number and no email list.
The tradeoffs are real. You get the wallet's design constraints, not your own. Update timing depends on the customer's phone. And there is no re-subscribe: a customer who deletes the pass is gone for good, which is why frequency caps matter more here than in email.
Where wallet passes are the wrong answer
If your customers visit less than once a month, no digital card will hold their attention — a prepaid package or a booking relationship will serve you better.
If your program needs to be redeemable by a partner business, or attached to a payment card, or personalised per transaction in ways a wallet field cannot express, you are describing something a wallet pass will fight you on.
And if a meaningful share of your customers do not carry a smartphone, paper is not a compromise, it is the correct tool.
