QR Codes on Event Tickets: Up-to-Date Info Without Reprinting – and Where the Limits Are

What a QR code on a ticket is good for

Tickets, invitations and posters carry details that may still change: room, start time, directions, programme. A dynamic QR code from Same-QR does not contain these details itself but a short address at Same-QR. You decide in the dashboard where it leads – and you can change that later without reprinting. Every ticket carrying the QR code then leads to the new destination.

The destination can be a website, a PDF with the programme, a small page you create directly in Same-QR, or a Zoom link for everyone joining online.

Last-minute changes without reprinting

If the event moves to another room or starts an hour later, you change the QR code's destination or the content of the page it leads to. Anyone scanning afterwards sees the new details. People who scanned earlier won't notice – so announce important changes by email as well.

On the free plan, each QR code gets two free destination changes. On the paid plans you can change the destination as often as you like. From the Gastro Pro plan, a QR code can also switch its destination by date and time on its own – for example to the lunch menu and to the dinner menu afterwards.

What Same-QR counts

Same-QR counts how often a QR code was scanned and shows this as one total per QR code in the dashboard. That tells you, for instance, whether the QR code on the poster is being used at all. So a hesitant camera doesn't count three times, the same internet connection is counted at most once per minute for the same QR code. Link previews from messengers and search engines don't count at all.

For this check, Same-QR does not store the IP address; it only keeps a salted hash for 60 seconds. Same-QR therefore doesn't know who scanned, and doesn't record when. One consequence: if several guests scan within a minute over the same Wi-Fi, that counts once. The number shows interest in your QR code – it is not a headcount.

What Same-QR is not: an entry system

Same-QR doesn't identify people and doesn't know which ticket belongs to whom. There is no check at the door, no invalidation after the first scan and no list of who is present. A ticket with a Same-QR code can also be copied – the QR code leads to the same destination every time.

For controlled entry you need a ticketing system that creates a unique QR code for each ticket and checks and invalidates it at the door. Same-QR complements such a system: the ticket QR code handles entry, while the Same-QR code on the ticket, poster or programme leads to the current details.

• A dynamic QR code leads to info you can still change after printing.
• What is counted is one total per QR code – no personal data, no timestamps.
• No entry control, no invalidation, no attendee list: that needs a ticketing system.
• Free: 20 dynamic QR codes, no credit card.
