QR redemption
What is QR redemption?
QR redemption is validating a gift card, voucher, ticket, or membership by scanning its QR code at the point of use, which marks it used — or deducts a balance or a single visit — in real time.
A QR code on a customer's phone or printout encodes a unique token. Scanning it with a staff app looks the item up, checks it is valid and not already used (or that it has balance or uses remaining), and records the redemption — all in a second or two, with no dedicated scanner hardware required.
The hard part redemption software has to get right is correctness under pressure: a busy door or counter where the same code might be scanned twice in quick succession. Zillo handles each redemption atomically and serialises concurrent scans, so a ticket can't be admitted twice and a multi-use pass can't be over-redeemed.
Different products redeem differently. A gift card deducts an amount from its balance; a single-use voucher or ticket is marked used outright; a multi-use voucher or capped membership deducts one visit and shows the remaining count. Each scan reflects the right behaviour, and an undo affordance reverses a mistaken scan.
QR redemption is what ties Zillo's online sales to the real-world moment of fulfilment, whether that is a barista, a door host, or a class instructor. It replaces paper vouchers, manual lists, and trust-based counting with a single tap.
