2 my-d products for contactless systems

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.

3 my-d vicinity products

my-d vicinity focuses on flexible memory and sector configuration with higher read/write distances.

This family of contactless memory chips supplies the user with different memory sizes and

optionally offers the use of security features meeting the requirements of variable applications. As

special feature the EAS (Electronic Article Surveillance) mode is built in to achieve higher and

more robust performance in the demanding EAS application.

my-d vicinity products are available in two memory sizes as well as in plain mode and in secure

mode:

• my-d vicinity plain mode with plain memory allowing unlimited access (SRF 55VxxP). Thus the

memory is organised in one sector.

• my-d vicinity secure mode allowing to configure counters and to secure memory access by

authentication measures (SRF 55VxxS). Thus the memory may be organised in up to 16

sectors with at least one sector in plain mode.

• 2,5 KBit memory sizes 32 pages with 10 Bytes (8 byte user data)

• 10 KBit memory sizes 128 pages with 10 Bytes (8 byte user data)

• In security mode advanced functions are available. Please refer to the relevant data book for

details.

All my-d vicinity products comply to the standard ISO/IEC 15693 for contactless vicinity smart

cards. The power supply and data are transferred to my-d products via an antenna. my-d vicinity is

designed to communicate up to a typical operating distance of 120 cm with a contactless reader in

an appropriate gate configuration.

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.

System Security

The serial number is unique for each label and can not be changed.
