Introduced in 2006, the ATC128-MV210 crypto transponder chip meets the need for a secure low-memory and cost-effective transponder in the 13.56 MHz area. With a user memory of 128bytes - enough to typically house 3 applications - the new transponder is designed for basic access control and leisure applications such as event ticketing and leisure passes. The ATC128-MV is a full member of the Legic advant product family. The ATC128-MV210 crypto transponder chip is fully compatible with the international ISO 15693 standard.

By expanding the reader chip functionality of its Legic advant product line to battery-powered applications, Legic now offers an alternative for stand-alone contactless physical access. Using a "low power" feature enables energy-efficient contactless door lock solutions. Until now, such stand-alone solutions (which repetitively power-down and wake-up the lock/card reader, thus saving energy) required the installation of expensive and bulky mechanical switches or infrared sensors as an energy-saving alternative to the wired "always on" readers. Beyond saving energy, this contactless solution is cost-effective (the simplified circuit reduces development and production costs) and can greatly extend battery life. The system is compliant with the FIPS 201 US government personal identity verification specifications.
