Your customers’ change, kept with you.
Sweets, airtime, IOUs on paper — and it isn’t only coins: a $10 note on a $1.50 bill is $8.50 you must find. Marii Cards keeps that change on a customer card instead, spent only at your till. The customer gets an SMS from you; you get a guaranteed next visit.
See how it worksOne tap on your counter, and your card is in their phone.
No app, no plastic to hand out. Your customers carry your card next to their boarding passes and bank cards — and it keeps their stamps, your specials and the way back to your shop in front of them.
A sticker on your counter
A Marii sticker by the till, with a QR code beside it. The customer taps it with their phone or scans the code with the camera.
Your card in their phone
Your card, in your colours, lands in Apple Wallet or Google Wallet. No app to download — a phone number and a six-digit code, in under a minute.
Stamps from the till
Give stamps at the till as you do now. The count on the card in their phone moves while they are still at the counter.
Specials on the card
Post a special and it shows on the card in every phone it may reach. No text needed, and nothing taken from your text allowance.
Nearby, on the lock screen
Set your shop’s location and, when a customer with your card is close by, their phone can bring it up on the lock screen.
Three taps, while the queue moves.
“Shall I put your $3.50 on your card?”
The ask is the default path — a scripted line on the till screen, not a policy your cashiers have to remember.
Tap their card or scan their phone
The card and QR are identifiers only — the value lives safely in the ledger, never on the plastic.
The SMS goes out — done
Sent under your shop’s name, with a link to what you are holding for them. Works when data is down; queued tills send themselves.
A worked example: on a $1.50 bill paid with a $10 note, the till puts $3.50 on the customer’s card and hands back a $5 note. Everyone’s square.
That change comes back. So does the customer.

Stop paying to reach strangers. Talk to the people who already shop with you.
The customers whose change you hold have bought from you, trust you, and have money waiting at your till. They don’t need convincing — just a nudge to come back this week. Marii puts your special on their phone, with no algorithm in the way.

Questions shop owners ask
Is the money really on the card?+
No value ever sits on the card — it is an identifier. Every cent lives in a ledger with a full audit trail, so a lost card loses nothing: the customer blocks it in seconds, staff link a replacement and what was on it is exactly where it was.
What stops a customer spending change that isn’t theirs?+
Spending needs proof it is them: the signed code on their own phone, or their card and their PIN — checked by our servers, never stored on your till. A phone number alone can receive change but never spend, and a photocopied card is useless without the PIN.
What happens when the network is down?+
The till keeps working. Keeping change, and spending with the code on the customer’s phone, both work offline — transactions queue on the device and send themselves when the signal returns. Spending by card needs a connection, because the PIN is checked by our servers and never kept on the till.
