The SLE 66R35x 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.
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 66R35x may also remain in the wallet of the user even if there are coins in it.
Access to SLE 66R35x is only allowed after a three-pass authentication. For SLE 66R35E7 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.
