What is sms enrolment?
SMS enrolment is signing a customer up to a loyalty programme by taking their phone number and texting them the card link, so the customer does nothing at the counter but receive a message.
Enrolment is the only step in a loyalty programme that happens once per customer and cannot be recovered later, which makes the method the highest-leverage decision in the whole system. The standard alternative asks a customer holding a coffee and a bag to unlock a phone, open a camera, focus on a QR code, wait for a page and type their details, at a till, with people waiting. SMS enrolment moves that work onto a staff member with a keyboard already in front of them: the number takes about three seconds to type, and the customer adds the card on their way out.
Why does SMS enrolment convert better than a QR code?
Because it removes every action from the person with both hands full. A QR code moves the work onto the customer at the worst possible moment; a typed number moves it onto the staff member, who is already at a keyboard and has a script.
The quieter half of the effect is on staff. A flow that feels awkward to ask for gets asked for less each week, which is why most programmes decay within about six weeks of launch rather than failing outright.
When is a QR code the better choice?
Where the customer is already stationary and has time: a restaurant table, a waiting room, a hotel room, a laundromat mid-wash. In those settings the friction that kills counter enrolment barely applies.
An unstaffed site is the other case, because there is no staff member to type anything. There the realistic flow is a sign the customer uses once while waiting.
What consent does SMS enrolment need?
Agreement to receive the card, which the customer gives by providing the number for that stated purpose, and separate agreement before any marketing is sent to it. Collecting a number to issue a loyalty card does not permit marketing to it.
Two sentences and two decisions at the counter is the version that stays compliant and still moves quickly. Recording when and how consent was given matters too, because the burden of proof sits with the business.

- Enrolment rate: Enrolment rate is the percentage of customers who join a loyalty programme when offered it, and it is the number that determines whether the programme is worth running.
- Friction: Friction is any step that stands between a customer and joining a loyalty programme, and each additional step measurably reduces how many people complete it.
- Double opt-in: Double opt-in is confirming a customer's agreement to be contacted a second time, through the channel itself, so that the business holds evidence the person who gave the number is the person who owns it.
- No-app loyalty: No-app loyalty is any loyalty programme that does not require the customer to install software, typically by delivering the card to the phone's built-in wallet instead.
