System Overview
The system consists of a contactless label on one hand and a contactless reader together with an
antenna on the other. Operations on protected areas of my-d vicinity in secure mode require a
mutual authentication with the reader. To achieve a high system security a Security Access Module
(SAM) holds the algorithm for performing the mutual authentication and integrity check of all data
exchange.

Contactless Energy and Data Transfer
The operating distance between label and reader antenna is typically up to 120 cm in an
appropriate gate configuration. The label antenna consists of a simple coil with a few turns.
Contactless labels are passive. The RF communication interface allows to exchange data with
26 kbit/s. This high data transmission rate permits short transaction times.
An intelligent anticollision function allows to operate more than one label in the field
simultaneously. The anticollision algorithm selects each label individually and ensures that the
execution of a transaction with a selected label is performed correctly without data corruption
resulting from other labels.
