Contactless Energy and Data Transfer
The operating distance between card and reader antenna is typically up to 10 cm. The card
antenna consists of a simple coil with a few turns embedded in plastic. Contactless cards are
passive. The high speed RF communication interface allows to exchange data with 106 kbit/s. This
high data transmission rate permits short transaction times.
An intelligent anticollision function allows to operate more than one card in the field 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.
Multi-Application Functionality
SLE 55R04 provides the possibility to use one large sector or several smaller ones with different
sizes.
Optionally, one sector can be opened without authentication to read e.g. additional card and issuer
information.
Thus, SLE 55R04 meets the need of low cost memory applications like public transport as well as
the more extensive needs of payment systems, which is also supported by the counter function.
Two different key sets for each memory sector support systems using key hierarchies.
High System Security
In the system design, special emphasis has been placed on security against fraud.
The serial number is unique for each card and can not be changed. Access to the protected
memory of the card is only possible after a mutual authentication (challenge/response) which is a
function of the unique serial number, random number and key to be used. Authentication is only
possible with a security access module, SAM, that holds the algorithm.
Therefore, for all operations on the protected memory, the SAM calculates and checks by a
message authentication code (MAC) the integrity of the transferred data. Thus, operations on the
protected memory are key protected, and restricted by page-configurable access conditions.
