Metrocard (Adelaide) - metrodroid/metrodroid GitHub Wiki

Metrocard is the smart-card ticketing system in use in Adelaide, Australia. It is operated by Adelaide Metro.

Metrocards are Mifare DESFire EV1 cards, with one application, 0xb006f2.

This card is essentially an Intercode card with following differences:

• It uses DESFire cards rather than Calypso
• Local time rather then UTC
• Counters are not readable
• Ticketing Env and Subscriptions have "Extra" fields populated.
• Expiry is set to 0x3fff probably meaning "No Expiry" but effectively making expiry "November 9, 2041"
