Rejsekort (Official translation: Travel card) is an electronic ticket system for public transport in Denmark.

Receipts are not given, and the trips can be checked online only after a few days, making it hard to verify that the correct amount was paid.

Therefore, the Rejsekort system was prepared to work with the Scanian, so as to allow passengers to easily travel over the Øresund Bridge.

The current cross border paper tickets are also accepted on local traffic, and should do so also in the future.

This is due to the not very successful end product, the doubled price-tag and the extreme delay in the original project plan.

[1] The card has a 4 kilobyte electrically erasable programmable read-only memory (EEPROM) which can be written to using RFID.

The original cards also contains a chip by NXP Semiconductors which implements a proprietary cryptography scheme called CRYPTO1, which was fully reverse-engineered in 2008.
