A free digital stamp card that runs on phone numbers

Do my customers need to download an app?

No. Their phone number is the card. Staff type it on the tablet, or customers scan the QR code on your counter poster and type it on their own phone. Both are free.

Is the free stamp card really free?

Yes. It is not a trial, and there is no limit on customers. It needs a free account and no card. Your list is on your account, so the tablet at the counter and the laptop in the office show the same one, and the QR poster, the kiosk and each customer’s card page work from the first day.

What does the paid plan add to the stamp card?

It adds review requests with no monthly cap: one per customer after a visit, then not again for a year. It adds a “we miss you” email when a regular stops coming. You choose how long away counts as too long, and KANJIN sends it. It adds slow-day emails: KANJIN drafts them, you read them and press Send. It adds a rainy-day email that goes out by itself on the first of 3 rainy days, at most once a week, in your own words. It also adds supplier payments and profit analysis. It costs $39 a month per location.

How many stamps should a reward take?

Ten is the default. A cafe with daily regulars can use eight to ten. A salon or barber, where visits are weeks apart, is better at four to six, so a customer sees a reward within a few months.

What happens to my customer list if I stop using KANJIN?

Export it whenever you like, on either plan: Settings hands you your customers and your items as spreadsheets, and everything in one file. Your customers’ data is yours. We never sell it, never email anyone without their yes, staff see only what you allow, and you can export or delete everything.
