What is a QR code on an e-ticket?
A unique, one-time scannable code that turns every ticket into a valid admission pass.
After a successful payment, Kaartjie automatically generates an e-ticket with a unique QR code, which is emailed to the visitor as a PDF. The visitor prints the ticket or shows it on their phone at the entrance.
Upon entry, scan the code with the free scanner app, directly in the browser on a smartphone or tablet — no separate hardware or installation required. The system remembers which codes have already been scanned.
If someone attempts to reuse a copied or previously scanned ticket, the scanner immediately displays an error message. This ensures reliable access control without any extra effort.
The QR code is included on the e-ticket as a PDF in the confirmation email, and iPhone users can also add the ticket to Apple Wallet . On Android, the visitor uses the PDF, which they can save to the gallery or a notes app so that the code is readily available. Each code can only be scanned once. If, in addition to the scan, you also want to know who is attending, you can use the "name per ticket" option to retrieve the name of each visitor and print a list of names afterwards.
