2
The SLE 66R35E7 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 66R35E7 may also
remain in the wallet of the user even if there are coins in it.
An intelligent anticollision function based on the chip's double size unique identifier (uid0-uid6) enables more than
one card in the field to operate simultaneously. The anticollision algorithm selects each card individually and
enables the execution of a transaction with a selected card is performed correctly without data corruption resulting
from other cards in the field.
The SLE 66R35E7 supports additional UID configurations allowing to operate SLE 66R35E7 in infrastructures
running 4-byte (single cascade) anticollision schemes only (short-cut anticollision, Random Number, FNUID).
Existing systems can remain unchanged. These options may be configured once during card personalization.
Access to SLE 66R35E7 is only allowed after a three-pass authentication. The serial number is unique for each
card and cannot be changed. 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 66R35E7 is suited for the use in multi-application schemes, for example combining a transportation fare
collection scheme and a ticketing system such as a 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.
2.1
The system consists of a host system, which is a contactless Read / Write Device connected to a background
system, the antenna and one or more SLE 66R35E7 based tags or other ISO/IEC 14443-3 Type A compliant
cards.
