Hitag 2 Card

Identification transponder for use in contactless applications.
Operating frequency 125 kHz.
Data transmission and supply energy via RF link, no internal battery.
Reading distance same as writing distance.
Non-volatile memory of 256 bits (128 bits user data, 128 bits control data and secret memory) organized in 8 pages, 4 bytes each.
Ten years non-volatile data retention.
More than 100000 erase/write cycles.
Selective read/write protection of memory content.
Two coding schemes for read operation: biphase and Manchester coding.
Effective communication protocol with outstanding data integrity check.
Mutual authentication function.
Read/write mode allows:
– Plain data transmission (password check)
– Encrypted data transmission (crypto mode).
In read/write mode multi-tag operation possible because of special HALT function
Emulation of standard industrial read-only transponders:
– Public mode A (64 bits read-only)
– Public mode B (according to ISO 11785 for animal identification)
– Public mode C (PIT compatible mode).

Special features:
User defined write protection
Unique 32-bit serial number for each transponder
Read-only emulation function
Encrypted data transmission possible.
