Communication
The physical contactless interface and communication protocol is defined for proximity by
ISO/IEC 14443 and for vicinity by ISO/IEC 15693 respectively.
my-d™ products support a set of standardized commands. Additionally Custom commands
are implemented providing e.g. 8-byte page memory access and optionally authentication
(secure variant).
Security
The memory can be accessed without security precaution (i.e. authentication) in plain mode.
The secure variants additionally require the mutual authentication procedure before memory
access is granted.
Short Product Information
– Sector Index (SI), defining either plain or secure memory access
– Access Condition (AC) holding information on access rights (e.g. read/write, read only)
