Most people don't leave home without a smart device and using a carrier that is almost always carried by the vast majority of customers, which can eliminate the hassle of tracking punch cards or delaying the experience. customer purchase by blocking queues. , etc., can be a powerful tool, but also a surprise for the customer when they pay for a cup of coffee, and suddenly it is "free", because their rewards have been automatically applied at the time of payment.
