Payment-linked auto-enrollment: turn every payment into a loyalty signup

The single best place to enroll a loyalty customer is the moment they pay. They have their card or phone out, the payment carries their identity, and there is nothing extra to ask. Here is how that works.

How payment-linked enrollment works

Your payment provider gives each location a way to attribute a payment to a person: a tokenized card and customer record through Stripe globally, or a virtual UPI address through Razorpay in India. When a customer pays, the payment arrives with details we can use to recognize and enroll them. The customer just pays as normal.

Zero taps for the customer

No form, no app, no card. By the time the payment confirms, they are enrolled and a loyalty pass is on its way to their WhatsApp. Your staff do not have to say a word or slow the queue.

Consent stays clean

Enrollment records consent with a timestamp, the welcome message explains what they signed up for, and a customer can opt out in one tap. It is built to GDPR and the DPDP Act, so you stay on the right side of the law while you grow your list.

• One payment identifier per location
• Identity read from the payment, not a form
• Pass delivered to the customer in seconds
• Consent logged on every enrollment

Retainx sets this up with you in about a day, including the payment provider side. After that, every payment quietly grows the list of customers you can bring back.
