About Digital tickets

Day passes, week passes and visit cards are easy to sell. Checking them at the door is the hard part: is this ticket real, and has it already been used? TWICE will sell a ticket like any other product, but nothing in it validates one at the entrance — which in practice means a list by the door and someone squinting at screenshots of emails.

GROU.Studio closes that gap. Each ticket product carries one setting saying what it grants: single use or a period, an optional visit limit and how long it stays valid. When an order is paid in full, every ticket on it is issued as its own QR code — two tickets on one order are two codes — delivered by email with a ticket page the customer can open on their phone, and saved on the order in TWICE. The code carries what it grants and a signature only your system can produce, so altering a single character makes it fail.

At the door, staff open the scanner in a phone browser and point the camera at the code, or paste it by hand. No app, no special hardware. A single-use ticket is spent on the first scan and a period pass counts each visit against its limit, so you end up with a record of how much every pass actually gets used. Two scanners cannot both accept the same visit, so a copied ticket gets in once at most.

Two things to know before going live. The signature proves a ticket is genuine, not that it is unused, so cancelling runs through a cancelled list rather than by unsigning anything: archiving or deleting the order in TWICE does that immediately — but a refund on its own does not cancel the ticket, so archive the order as well. And the tickets themselves are issued by a small service alongside TWICE, which stays your shop for products, checkout, payments and orders.
