The Cango Tickets QR-Scanner app can be used to validate tickets generated by the Cango Ticketing system. All e-tickets that are sent by email contain a unique QR-code. The scanner app can tell the organisation of an event if the ticket is valid, non-valid or already scanned. It will make the life of the organizer of an event easier, queues shorter and people happier! Thank you for choosing Cango Tickets and using our app.
