What is a digital stamp card?
A digital stamp card is the phone version of the classic paper punch card: customers earn a stamp per visit or purchase and get their reward when it is full (e.g. "5 coffees = 1 free"). Unlike points, it counts visits, not spend. With Socios, stamping takes 3 seconds by scanning a QR code.
Perfect for high-frequency businesses like cafés, hair salons, bakeries and anywhere customers come back regularly.
