Mifare
System Overview


SLE 66R35 is designed to operate in the Mifare
system. Mifare
is a contactless proximity smart
card system compliant to ISO/IEC 14443-2 and -3. The system consists of a smart card and a card
reader together with an antenna.
Contactless Energy and Data Transfer

In the Mifare
system the operating distance between card and reader antenna is up to 10 cm and
more (influenced by external circuitry i.e. reader-antenna configuration). The card's antenna

consists of a simple coil with a few turns embedded in plastic. Mifare
cards are passive - they do
not contain a battery. The high speed RF communication interface transmits at up to 106 kbit/s.

Mifare
- The User-Friendly Contactless System

The Mifare
system is designed to be user-friendly. High data transmission rate results in short

transaction times, the effect being that a Mifare
card user can move freely through a reader gate
with minimum disruption. A typical ticketing transaction can be handled in less than 100 ms.

Robust contactless transmission means that the Mifare
card may also remain in the wallet of the
user even if there are coins in it.
An intelligent anticollision function enables more than one card in the field to operate
simultaneously. The anticollision algorithm selects each card individually and ensures that the
execution of a transaction with a selected card is performed correctly without data corruption
resulting from other cards in the field.
Multi-Application Functionality

The Mifare
system is especially suited for the use in multi-application schemes, for example
combining transportation revenue collection scheme and a ticketing system, for example stadium
ticketing. Both applications can be performed with the same card, as hierarchical key management
is supported. This means that two different keys for each memory sector can be assigned to
enable authentication to that sector.
System Security

In the Mifare
system design, emphasis has been placed on security against fraud. Access to the
card memory is only allowed after a three pass authentication. The serial number is unique for
each card and can never be changed. Each data transmission is enciphered. Configurable access
conditions protected by secret keys for memory operations as read or write protect from misuse.
