tapja for bubble tea
Your customers already have the phone in their hand.
Bubble tea lives off young guests who come often and do everything on their phone. That is exactly where the stamp card belongs: in the wallet, with no app for your guests.

Sound familiar?
From frustration to fix.
The shop next door has the same flavours.
A stamp balance you cannot take with you keeps guests here.
Paper cards vanish into a school bag.
The card sits in the wallet, never misplaced again.
Afternoons are packed, mornings nothing at all.
A morning offer shifts visits into them.
How it works
Up and running in three steps.
Design the card
Pick a card type, set your logo and colors, define the reward rule, for example "10 cups, the 11th free.". The live preview shows instantly how the card looks in the wallet.
Onboard customers
The customer scans the QR code at the counter and adds the card to their wallet with one tap. Done, no app for your guests.
Collect & reward
One tap is all it takes: the balance updates automatically on the card, and when a reward is reached a wallet notification lands on the phone.
Example program

A day with tapja
How it feels in everyday life.
A student comes in after class. Paying up, she scans the QR code at the counter and the card is in her wallet two seconds later, with no app of her own. Your team taps "stamp" in the staff app: 8 of 10. When you add a new flavour in summer, a notice goes out to every regular. She tries it that same afternoon. On the tenth stamp the eleventh cup is on the house, redeemed right at the counter, and the card starts over.
From €0, free forever for up to 30 cards.

When does a stamp card start to pay off?
Two pages with the arithmetic: contribution margin per visit, monthly cost, and the number of extra visits at which the card pays for itself. In return for signing up to our emails; one click unsubscribes.
Common questions about tapja for bubble tea shops.
Question not listed?
Write to us, a person will answer.
Some of our customers are minors. Does that work?
An account needs a name, an email and an email confirmation. Whether you issue cards to minors and how you handle consent is your decision: the same consideration as with any other customer programme, and worth clarifying up front.
Does it work in the afternoon rush?
Yes. Your team taps the stamp in the staff app and holds the guests phone next to it, which takes under two seconds, faster than hunting for a paper card.
Can we announce new flavours?
Yes, as a wallet update. The notice lands on your regulars lock screen, not in an inbox. For this audience it is the one channel that reliably arrives.
What does this cost a small shop?
The free plan is free forever and covers up to 30 active cards, one programme and two staff accounts. Beyond that, Favourite Spot starts at €29 a month, cancellable monthly.
Do my guests need an app?
No, your guests need no app. The card lives in Apple or Google Wallet, already installed on every smartphone. No account, no password, just a one-off email confirmation.
Do my customers need an app?
No. The card lives right in Apple or Google Wallet. Both are already on the phone. No download, no login for your customers.
How does the card get onto the phone?
Via the QR code on the counter stand: scan once, "Add to Wallet," done. The card is on the phone in seconds.
Is it GDPR-compliant?
Yes, GDPR by design: data minimisation, servers in the EU and a separate marketing consent. From your guests you need a name and an email, nothing more.
