Compatible with MIFARE 1k, the MIFARE 4k are the memory capacity up to 4kBits.

MIFARE 4k 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 London, Beijing,Taipei, Pusan and many more are adopting MIFARE as the contactless interface platform for the present and future.

MIFARE 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.

Contactless smart cards MIFARE Classic of NXP are used in many of the same applications as contact smart cards, especially where the added convenience and speed of not having to insert the card into a reader is desirable. There is a growing acceptance of this type of card for both physical and logical access control applications. Student identification, electronic passport, vending, parking and tolls are common applications for contactless cards.
