MIFARE is a proven, reliable and robust technology for contactless smart cards. High volume IC manufacturing with leading process technologies and assembly experience has led to the issuance of over 3,5 billion cards and the installation of 40 million readers and terminals in applications around the world. And with more than 1.000 registered partners, multiple sourcing for cards and readers is guaranteed no matter where you are located.

With a complete product portfolio (including ICs for limited-use paper tickets as well as microcontrollers for dual interface smart cards with PKI crypto engines capable of hosting multiple applications), MIFARE offers the right product for every application. And as an open architecture platform, it guarantees compatibility with all current and future products.

MIFARE based smart cards are being used in an increasingly broad range of applications (including transport ticketing, access management, e-payment, road tolling, and loyalty applications). While all of these applications could be stored on one single card, at least for the short term, it is more likely that people will have several different MIFARE based smart cards in their wallets.

To maintain the speed and convenience of MIFARE‘s tap-and-go operation, the MIFARE Application Directory (MAD) defines common data structures for card application directory entries, allowing terminals to identify the right card (and the right memory sector within the card) without the need to perform a comprehensive search through all of the cards’ memories until the appropriate application is found.

Started in 1995, we have more than 600 registered applications worldwide benefiting from the MIFARE Application Directory today.

A typical example is when a person has MIFARE based smart cards for both access management to his office and public transport fare collection. With the MAD, when the cardholder wants to enter his office, the access management terminal identifies the two cards and is able to choose the correct one very quickly, simply by checking the MAD.

The MAD standard uses registered Application IDentifiers (AIDs) in sector 0×00 (and sector 0×10 if applicable) of the card’s memory to enable identification of all registered card applications. Terminal software can then take advantage of this feature using these sector pointers instead of physical sector addresses.
