Punch card
A punch card is a paper loyalty card that a business marks — with a hole punch or a rubber stamp — once per visit or purchase. When the card is full, the customer earns the reward printed on it.
Also called loyalty card, stamp card, buy-nine-get-one-free card.
Why they have lasted
Because they work, and it is worth being honest about that before replacing one. A punch card costs almost nothing, needs no setup, keeps working when the internet is down, and no customer in history has needed it explained. Any replacement is competing against something genuinely good at its job.
What they cost you
Not the printing. The cost is that you cannot answer basic questions — how many cards are in circulation, how many people are one stamp from a reward, whether the regulars from six months ago still come. It is a discount running with no instrumentation, so you cannot tell whether it is winning custom or quietly subsidising people who were coming anyway.
The leakage nobody measures
Punch cards get punched by friends, borrowed, and completed with a hole punch bought for a few pounds that matches yours closely enough. Most businesses running paper accept a level of loss they have never quantified, and the figure surprises them when they eventually measure it.
Questions
- Are punch cards still worth using?
- For a single site with a fast queue, no interest in marketing to customers later, and poor mobile signal, paper is a defensible choice. The case for changing starts when you want to know who has stopped coming.
- Can paper and digital run at the same time?
- Yes, and it is the usual way to switch. Keep honouring paper cards already in circulation while new customers join digitally, and let the paper ones age out.

A digital stamp card is a loyalty card that lives on a customer’s phone instead of in their wallet. Staff add a stamp by scanning a code at the counter, and once the card reaches a set number of stamps the customer has earned a reward.
Stamp
A stamp is a single credit on a loyalty card. Staff add one when a customer makes a qualifying purchase, and collecting the required number — often ten — earns the reward.
Loyalty program
A loyalty program is an arrangement that rewards customers for coming back. In hospitality it usually takes one of two forms: stamps counted per visit toward a free item, or points accrued against how much is spent.
