What is a digital loyalty card?
A digital loyalty card is the phone version of the paper stamp card: customers earn a stamp with every purchase and get a reward when they reach a set number. The coffee loyalty card is the best-known example: one gift for every ten coffees.
A digital stamp card applies the same rule without paper. With sipnik, the stamp card lives in your brand's own app, right next to the wallet balance.

Questions

The customer has their QR scanned at the POS, and the stamp is added along with the payment. When the card is full, the reward is ready in the app and redeemed at the POS with a single tap.
Does the customer need to download an app for a digital punch card?
Yes; stamps and rewards are kept in your brand's app. The customer downloads it once, and after that having their QR scanned at the POS is all it takes.
How do I move my coffee loyalty card from paper to digital?
Choose the reward and the rule, set up the stamp card in the dashboard and ask for the QR at every payment. We handle setup and training.
Does the café loyalty card work at all my branches?
Yes. Stamps and rewards earned at one branch can be used at all of your brand's branches.
Stamp card or cashback: which is better?
A stamp card is simple for customers who often buy the same item; cashback is flexible for those who buy different things. You can also run both together.
Can I use the digital loyalty card with my own POS software?
Yes, optionally: it connects to your current POS software via API, and QR stamps and wallet payments work there too. The recommended path is sipnik POS, with setup and training included.

The campaign report shows how many people joined, how many rewards were given and what it cost you.
