E-tickets are electronic tickets that are increasingly replacing conventional admission tickets or travel tickets. A wide spread of paperless e-tickets can be observed in the travel industry at airlines and passenger trains, but also at major events.
E-ticketing has the advantage that customers can conveniently view travel details and purchase an e-ticket on their computer. When they book, they receive this as an attachment with the e-mail confirmation. The e-ticket is made out to the traveler and contains all the travel details such as the departure city, departure time, arrival airport, arrival time, flight numbers, etc. It can be downloaded to the smartphone as a QR code.
The identity of the traveler is verified via the passport at the check-in counter or via QR code readers in passenger trains by the conductor. In public transport, the e-ticket is often stored in the form of an electronic data record on a chip card or as a mobile ticket on a smartphone. Multiple use of e-tickets is ruled out when the QR code is checked.
