MIFARE™ Classic 1K

MIFARE Classic 1K was the first IC to be used in high volume public transport ticketing in a major transport project in Seoul, Korea. Continuing this success, cities such as São Paulo, Buenos Aires, Taipei, Pusan and many more are adopting MIFARE as the contactless interface platform for the present and future.

MIFARE Classic 1K is primarily used in closed systems as fixed value tickets (e.g. weekly or monthly travel passes) or as tickets where value is extracted from the card by the service provider.

From May 2010 onwards, a MIFARE Classic 1K variant is also available with a 7 Byte UID. For future outlook regarding the 4 Byte UIDs see 4-7Byte UID.
