my-d products for contactless systems are designed to meet the increased security and flexibility
demand of the market. This family of contactless memories supports the different interface and
memory size needs as well as various security requirements for variable applications.
The product series functional architecture (e.g. memory organisation, authentication) is the same
for both proximity (ISO/IEC 14443) and vicinity (ISO/IEC 15693). This eases the system design
and allows simple adaptation of applications from my-d proximity to my-d vicinity or vice versa.
Applications are supported very flexible by setting the appropriate mode for the my-d product,
starting with plain mode with a page locking mechanism up to various settings in secure mode for
multi user / multi application configurations with tearing protected counters. In secure mode a
strong cryptographic algorithm with 64 bit key length is additionally available for security
mechanisms like mutual authentication and message authentication codes.

These powerful features make the contactless security memory product series my-d ready to cope
with even high-end requirements. Architectural compatibility of all my-d products allow an easy
migration path from simple to powerful demanding applications.
