Event ticketing
Print the tickets with your own artwork, sell them at the box office, and check them at the door with a phone. At any moment you know how many are in, how many are still to come, and how much has been taken.
The detail that changes everything
Opens the link and jumps to the address the organiser chose. It jumps in exactly the same way whether the ticket is valid, already used, or fake.
Goes nowhere. It reads the code, checks it against the server, and answers in large letters: valid, already used, or alarm.
The destination page always answers the same way, whatever the ticket.
Upload your artwork, choose the sheet and how many tickets per sheet, and place the code. The app tells you to the millimetre what the image needs to be, and prints with crop marks.
Tickets are scanned one by one at the box office, with the batch price and the payment method. At the end of the event the cash-up comes out per seller.
At the door, the phone reads the code and answers in large letters. If two entrances read the same ticket, only one validates it; the other sees who validated it first.
The phone downloads the list before the event. If the network drops it carries on checking tickets and syncs by itself when it comes back — with a red bar always in sight, so nobody is left thinking all is well.
A ticket that turns up at the door having never been sold is not a routine refusal: it is an alarm on the screen, on the dashboard, and on the organiser’s phone.
How many are in, how many are still to come, how much has been taken, and how fast people are coming through the door.
