The my-d™ products are designed to meet increased demands for basic security and design
flexibility. The my-d™ family of contactless memories supplies the user with different memory
sizes and incorporates security features to enable considerable flexibility in the application
design.
The functional architecture, meaning the memory organization and authentication of my-d™
products is the same for both my-d™ proximity (ISO/IEC 14443) and my-d™ vicinity (ISO/IEC
15693 or ISO/IEC 18000-3 Mode 1). This eases the system design and allows simple
adaptation between applications.

my-d™ products are available in
– plain mode with open memory access,
– secure mode with both memory access controlled by authentication procedures (up to 14
– additional small tag antenna designs are possible with the HC variant providing high on-
Applications may start with the my-d™ ICs in plain mode operation and individual page
locking; for more complex applications various settings in secure mode can be used for multi
user or multi application configurations.
In secure mode a cryptographic algorithm based on a 64-bit key is available. Mutual
authentication, message authentication codes (MAC) and customized access conditions
protect the memory against unauthorized access.
Configurable value counters, featuring anti-tearing functionality, are suitable for value token
applications such as limited use applications.
Architectural interoperability of all my-d™ products enables an easy migration from simple to
more demanding applications.
In addition, the my-d™ light (ISO/IEC 15693 or ISO/IEC 18000-3 Mode 1) is part of the my-d™
family. Its optimized command set and memory expands the range of cost optimized
applications.
