QR payments on Kit Pay
Scan to pay or show a code to be paid — how Kit Pay QR codes work, and why signed codes are hard to fake.
A QR code is a phone-readable way to say "pay this account" — and on Kit Pay, often "pay this account this exact amount". Scanning replaces typing, which kills the two classic counter mistakes at once: the mistyped number and the misheard amount.
The two directions
- Scan to pay: point your camera at a code someone shows you, and the payment screen opens with their details filled in for your review.
- Show to be paid: display your code and let the other person scan — the natural direction for traders, covered in taking payments at your counter.
Amount-bound and open codes
Some codes carry only who to pay, leaving the amount to the payer — right for donations and flexible sums. Amount-bound codes carry the agreed price as well, locking the payment to what was agreed: the buyer cannot underpay by sleight of thumb, and the seller cannot inflate after the nod. For anything with a negotiated price, amount-bound is the shape that keeps both sides honest. Amount-locked versus open codes goes deeper.
Why signed codes matter
Kit Pay merchant codes are cryptographically signed: the app checks a code's signature before treating it as genuine, so a stranger cannot mint a code that impersonates a legitimate business. A tampered or unsigned imitation fails the check instead of quietly redirecting money. Signed QR codes explains what that means in practice.
Paying by scan for the first time? Pay by scanning a QR code is the step-by-step version, including what to check before you approve.
Frequently asked questions
Can a QR code take money just by being scanned?
No. Scanning opens a payment screen for your review; money moves only after your approval, tied to that payment.
What if a printed code at a stall has been swapped by a fraudster?
The review screen shows who you are actually paying — check the name matches the business in front of you before approving, and signed merchant codes make wholesale fakes fail verification.
