| MIFARE DESFire is
based on open global standards for both air interface
and cryptographic methods. It is compliant to
all 4 levels of ISO / IEC 14443A and uses optional
ISO / IEC 7816-4 commands.
Featuring an on-chip backup management system
and the mutual three pass authentication, a MIFARE
DESFire card can hold up to 28 different applications
and 16 files per application. The size of each
file is defined at the moment of its creation,
making MIFARE DESFire a truly flexible and convenient
product.
Additionally, an automatic anti-tear mechanism
is available for all file types, which guarantees
transaction oriented data integrity. With MIFARE
DESFire, data transfer rates up to 424 Kbit/s
can be achieved, making fast data processing possible.
The chip’s main characteristics are denoted
by its name DESFire – DES indicates the
high level of security MIFARE DESFire achieves
using a 3DES hardware cryptographic engine for
enciphering transmission data. Fire reflects its
outstanding position as a Fast, Innovative, Reliable
and sEcure IC in the contactless proximity transaction
market.
Hence, MIFARE DESFire brings many benefits to
end-users. Cardholders can experience convenient
contactless ticketing while also having the possibility
to use the same device for related applications
such as payment at vending machines, access management
or event ticketing. In other words, the MIFARE
DESFire silicon solution offers enhanced consumer-friendly
system design, in combination with security and
reliability.
MIFARE DESFire delivers speed, performance and flexibility. Its open
concept allows future seamless integration of
other ticketing media such as smart paper tickets,
key fobs, and mobile ticketing based on Near Field
Communication (NFC) technology. It is also fully
compatible with the existing MIFARE reader hardware
platform.
MIFARE DESFire is your ticket to contactless
systems worldwide.
