Moving From Paper Stamp Cards to a Digital Loyalty Program

By Alva Chew · Updated 2026-11-01

In short To replace paper stamp cards with a digital program, price one stamp in points, honour every half-full card at that rate, and set a cut-off date. A US$5 coffee earns 5 points, a free coffee costs 45, and a customer holding 6 stamps starts with 30. A digital stamp card is only one option, and points do the same job while also rewarding bigger bills.

What does moving from a paper stamp card to a digital program involve?

You change four things. The unit that is counted, the place the balance lives, the way staff record a purchase, and what happens to the paper cards already in customers’ wallets. The last one is where most switches go wrong.

A paper stamp card counts visits or items. A digital program keeps the balance on the customer’s phone and in your records, so you can see it and the customer cannot lose it. The unit you count is your decision, and it is the one worth making carefully.

A digital stamp card is the simplest copy of the paper one. It keeps the stamp, and with it the limits of the stamp: a US$4 coffee and a US$40 lunch earn the same, and a group order forces staff to decide how many stamps to give. Gimify has no stamp mode. Points replace the stamp and keep everything the paper card did. Our stamp card vs points comparison sets out the differences, and the glossary entry on stamp cards defines the term.

Why switch from paper at all?

Three practical reasons come up for shop owners.

You cannot see paper. You do not know how many cards are out, how many are nearly full, or which branch hands out the rewards.
Paper gets lost and copied. A card left in a coat pocket is a customer who restarts from zero or stops coming. A stamp pressed with a cheap ink pad is easy to fake.
Customers carry phones. Pew Research found that 91% of US adults own a smartphone in its 2026 survey.

The same phone is what makes the switch easy. A customer does not need to download anything. Research from comScore found that 51% of US smartphone users downloaded no apps in a month in 2017, so a loyalty program that depends on an app asks for something most customers will not do. We cover the options in a loyalty card with no app to download.

How do you convert a stamp into points?

Price the stamp. Take the item your stamp card is built around, decide how many points per dollar you give, and work out what one stamp was worth.

Take a café with a buy-nine-get-the-tenth-free card on a US$5 flat white, switched to 1 point per US$1:

Step	Result
Each flat white earns	5 points
Free flat white costs	45 points
One paper stamp is worth	5 points
Customer holding 6 stamps starts with	30 points
Customer holding 9 stamps starts with	45 points, a free drink

The reward is the same as before. The difference appears for everyone who buys more than a flat white. A customer who adds a US$6 croissant earns 11 points, not one stamp. Our guide to setting a points earn rate shows how to choose the points per dollar and the reward size so the reward costs a share of spend you can afford.

Keep the numbers round. Many owners use 2 points per US$1 so that a drink earns 10 points and the free drink costs 90. A customer who sees “70 of 90” understands that two coffees remain.

What should you do about half-full paper cards?

Honour them. A customer with seven stamps has already spent money on your promise, and a refusal turns a regular into a former customer.

Pick a cut-off date. Four to eight weeks out is enough for most shops to see every regular once.
Announce it at the counter. A small sign and a sentence from staff at the till are enough. Tell customers their stamps will be converted.
Convert at the rate you chose. Count the stamps, multiply by the points per stamp, and have staff add that balance to the customer’s new card. Staff add points on any phone at the counter.
Collect the paper card. Keep it or mark it, so it cannot be converted twice.
Stop issuing paper cards on day one. After the announcement, every new customer joins the digital program.

Round up in the customer’s favour when a stamp falls between two values. The cost is a few cents per card, and the goodwill is worth more.

Does the research on stamps still apply once the card is digital?

Yes, and it favours showing progress, whatever the unit. Two studies are cited most often:

At a university café, the time between coffee purchases fell by about 20% as customers neared a free drink. Kivetz, Urminsky and Zheng, Journal of Marketing Research, 2006.
At a car wash, a 10-stamp card with 2 stamps already filled was completed 34% of the time, against 19% for a blank 8-stamp card needing the same 8 washes. Nunes and Drèze, Journal of Consumer Research, 2006.

Both measure the pull of a reward that looks close. A points balance shows the same thing as “70 of 90”, and converting old stamps gives every customer a head start in the same way as the pre-filled stamps in the car wash study. Starting the digital card with the customer’s converted balance, not at zero, is the practical use of that result. The wider case is in why the simplest loyalty program wins.

How do you brief staff and customers?

Staff need one rule: points are earned on the bill. Write it on a card by the till. No one has to decide how many stamps a group order is worth, because the payer earns points on the total.

For customers, keep the pitch short and about them: scan the code, enter an email, and the balance is on your phone. Our page on the digital loyalty card defines what the card holds. Offer to set up the first sign-up at the counter, because the first scan is the step where customers hesitate.

Customers who do not want a digital card still need serving. Staff can look up a member and add or redeem points, so the customer does not have to show a phone.

What does a digital program cost compared with paper?

Paper costs printing and the stamp pad. A digital program costs software, and the price depends heavily on how many outlets you have. Fees per location, per member or per message change the answer once you open a second shop, so check the vendor’s own pricing page before committing.

Gimify’s free plan covers one outlet with unlimited members and no time limit. Unlimited outlets cost US$99 a month, with one points balance across every outlet.

What is a sensible switch-over plan?

Week 0: choose the points per dollar and the reward size. Test the numbers on your three most common orders.
Week 1: put up the sign, brief staff, stop issuing paper cards and open sign-ups at the counter.
Weeks 2 to 6: convert paper cards as customers present them.
Cut-off date: stop accepting paper stamps and tell any stragglers in person.
After the cut-off: read the balances and the first redemptions to check the reward cost is what you planned.

Gimify is points only, with no stamp mode, so your converted stamps become a points balance in a card kept in Google Wallet. Customers join by QR code and email with no app, and your first outlet is free.

Questions owners ask

What is a digital stamp card?

A digital stamp card is a stamp card kept on the customer's phone instead of paper. Staff add a stamp per visit or item, and the customer sees boxes filling. Gimify has no stamp mode. It runs points only, earned on what each customer spends.

How do I convert paper stamps to points?

Divide the price of the stamped item by the points per dollar. At 1 point per US$1 and a US$5 coffee, one stamp equals 5 points. A customer with 6 stamps starts with 30 points, and a free coffee at 45 points matches a 9-stamp reward.

What happens to customers with half-full paper cards?

Honour them. Set a cut-off date, announce it at the counter, and convert each card to points at the rate you chose. Refusing old stamps is the quickest way to lose the regulars you most want to keep.

Will older customers cope without a paper card?

Most will. Pew Research found 91% of US adults own a smartphone in 2026. Customers join by scanning a QR code and entering an email, with no app. For anyone who prefers not to, staff can still look a member up and add points.

Should I run paper and digital cards side by side?

Only for a short, fixed period. Two systems double the staff rules and the counter arguments. Pick a cut-off date four to eight weeks out, convert cards until then, and stop issuing paper cards on day one.

Is a digital program free to start?

On Gimify, one outlet is free with unlimited members and no time limit. Unlimited outlets cost US$99 a month. Check any vendor's own pricing page before you switch, since per-location fees change the cost of a second shop.
