How to get customers to add your loyalty card at the counter

You designed the card. It looks right in the wallet. Now comes the part that decides whether the program does anything: getting it onto your customers' phones.

Every card that goes into a wallet becomes a customer you can see, count and reach. Every one that does not is a person who will pay, leave and be a stranger next time. The whole return on a loyalty program is set by the share of customers who add the card, and that share is decided in about four seconds at the counter.

Here is what moves it.

1. Put the code where the phone already is

The customer's phone is out when they pay. Put the QR code next to the card reader, at the height of a phone held to tap. A counter card that stands up, twelve centimetres tall, right beside the terminal, is the single highest-converting placement we have seen.

A poster on the wall behind the counter is good for awareness but poor for action. People read it while queuing and forget it by the time they pay. Use both: the poster tells them a card exists, the counter card is where they scan it.

2. Say what they get, in five words

The sign should not say "Join our loyalty program". It should say what the customer gets: "10th coffee free. Scan to add." The reward is the reason. The action is the instruction. Nothing else.

If your card has a welcome reward (a stamp for adding it, a free pastry on the first visit) put that on the sign. "Scan for a free stamp" turns a maybe into a yes for a lot of people.

3. Ask, once, at the moment of paying

Signs do a lot, but the ask from a person does more. The line is short and the same every time: "Do you have our card? Scan that and your tenth one's free."

It works because it is a question, so it needs an answer, and because the offer is in the same breath. Staff should say it once and drop it. Never argue with a no, never ask twice in the same visit, and never make the customer feel slow.

If a customer asks what it is, the answer is one sentence: "It's our stamp card, but in your phone's wallet, so you can't lose it." There is no app to download and no account to make, and most questions end there.

Practise it in the first week until it is automatic. The shops that get to sixty and seventy percent of regulars on the card are the ones where every team member asks every time.

4. Make the scan the whole job

Between scanning the code and having the card in the wallet there should be exactly one screen and one tap. The customer scans, a page opens with your card on it, they tap "Add to Apple Wallet" or "Add to Google Wallet", and it is done.

Every extra step costs people. A form with five fields costs half of them. An app download costs nearly all of them. If your sign-up asks for anything beyond a first name, ask yourself whether you actually use that data. If you do not, remove the field.

The one exception is a question you genuinely need, like a birthday for a birthday reward. Ask for it after the card is in the wallet, not before.

5. Give the first stamp on the spot

A card with zero stamps is an empty promise. A card with one stamp is a thing in progress. When someone adds the card at the counter, stamp it right then, for the purchase they are making. Better still, give a welcome stamp for adding it, so they walk out with two.

This is the endowed progress effect and it is well documented: people finish things they have started far more often than things they have not. Two stamps of ten feels like a head start. Zero of ten feels like a chore.

6. Let the card come back on its own

Once the card is in the wallet, the wallet does some of the work. Set your shop's location on the card and it appears on the customer's lock screen when they are nearby. That is a reminder you did not have to send, at exactly the moment they could act on it.

It also solves the second-visit problem. The customer does not need to remember they have a card. It is on the screen when they walk in.

Messages do the same job over a longer stretch. A regular who has not been in for a few weeks can get a short note on the lock screen: "We miss you. Your next stamp is on us." Keep them rare and useful and they stay welcome.

What good looks like

Shops that do all six of these see something like a third of new customers add the card in the first month, and well over half of regulars on it within three. Shops that put up one poster and wait see a few percent.

The difference is not the card. It is the counter. Put the code where the phone is, say what they get, ask once, make it one tap, stamp it immediately, and let the location do the rest.

Print the counter card. Every card comes with posters and counter cards in your colours, with your QR code, in twelve languages. Print one tonight and stand it next to the reader tomorrow.
