2 Overview of a Mifare compatible System
The SLE 66R35 / SLE 66R35I / SLE 66R35R is designed to operate in a Mifare compatible
system. The system consists of a smart card and a card reader together with an antenna.
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.
The RF communication interface transmits at 106 kbit/s resulting in short transaction times, the
effect being that a 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 card with SLE 66R35 / SLE 66R35I / SLE 66R35R may also remain in the wallet of
the user even if there are coins in it.
An intelligent anticollision function based on the chip single size identifier (UID0 – UID3) 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.
Access to SLE 66R35 / SLE 66R35I / SLE 66R35R is only allowed after a three pass
authentication. Each data transmission is enciphered. Protection from misuse is done by
configurable access conditions that are protected by secret keys used for memory operations such
as read or write.
Multi-Application Functionality
The SLE 66R35 / SLE 66R35I / SLE 66R35R is suited for the use in multi-application schemes, for
example combining a transportation fare collection scheme and a ticketing system such as 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.
