Mifare is the leading brand for a wide range of contactless products with a typical read/write distance of 10 cm (4 inch). The use of these chips has increased tremendously, especially since they are so cheap. Mifare has proven popular as the card to use in ticketing and low value transactions.
For access control, Mifare Classic and Mifare Desfire cards are most used. These two variants differ from each other with regard to mechanical security, price and the way in which data (encrypted) are stored. Data on a Desfire EV1 chip are more secure and resistant to hacking than on a Classic chip.
