How it works
A paper card,
without the paper.
Stampkaro is the stamp card your customers already understand, kept on the mobile number they already have. No app for them to download. No POS for you to replace.
For your customers
Thirty seconds,
once.
This is the whole thing they ever have to do. After the first visit there is nothing to open, remember or carry.
01
They scan the QR on your counter
With the normal camera app. Nothing to download, nothing to install — this is the part shop owners expect to be a problem and it is the part that isn't.
02
They type their mobile number
We send a code on WhatsApp, they tap it in, and they tell us what to call them. This happens once, ever, across every shop that uses Stampkaro.
03
Their card opens
It lives on their mobile number, not in an app. Nothing to lose, nothing to reinstall when they change phones.
04
Every visit after that is automatic
They give their number at the counter and walk away. Their stamps go up, and we message them the card so they can see it.
For you
Four things,
then it runs itself.
Setting up takes an afternoon at most. Running it is one tap per customer, done by whoever is already standing at the till.
01
Pick a plan and set up autopay
Two plans, both uncapped on customers, visits and staff. The only thing that differs is how often we message your customers on your behalf.
02
Write your rewards ladder
“Free filter coffee at 3, a pastry at 8, ₹200 off at 15.” You can change it whenever you like — your customers' progress carries over.
03
Put the QR where people pay
Print it yourself from the dashboard, or we bring you a standee. The same QR signs up new customers and brings back anyone who removed their card, with their visits intact.
04
Your counter taps once
Staff type the last four digits of a number and tap. Under five seconds, no POS change, no training. If a reward is ready they see it before the customer asks.
The bits people
always ask about.
- Do customers need an app?
- No. Their card is a web page tied to their mobile number. It opens from any WhatsApp message we send them, on any phone.
- Does it touch my billing system?
- No. Stampkaro sits beside whatever you already use. Nobody has to re-enter a bill, and there is nothing to integrate.
- What if someone changes phone?
- Nothing happens. The card belongs to the number, not the handset — they scan your QR again and every stamp is still there.
