The my-d™ vicinity products are based on ISO/IEC 15693 or ISO/IEC 18000-3 Mode 1
standards for contactless vicinity cards.
The my-d™ vicinity focuses on applications with memory demands of up to 10 kbit EEPROM.
3.1
The my-d™ vicinity is made up of an EEPROM memory unit, an analog interface for
contactless energy and data transmission and a control unit.
