Welcome to high security

The module supports the latest contactless MIFARE® and DESFire® EV2 chip technologies, with their new data protection measures:

  • Secure Messaging EV2 : a method that secures transactions by protecting them against interleaving and replay attacks.
  • Proximity Check : protection against relay attacks.

All public encryption algorithms can be used (3DES, AES, RSA, SHA, etc.), which are recommended by official data security agencies (such as the French national agency ANSSI).

Migrate in complete peace of mind

The MS2 simplifies the management of extensions, upgrades and technological migrations.
It is compatible with many 13.56 MHz contactless identification technologies :

  • MIFARE® : Ultralight® & Ultralight® C, Classic & Classic EV1, Plus® & Plus® EV1, DESFire® 256, EV1 & EV2,
  • CPS3,
  • NFC smartphones (HCE),
  • PicoPass® and iCLASS™* (CSN only).

When migrating, or in complex multi-site configurations, it can be used to read different types of badges and to gradually switch to mobile technologies.

Flexibility & Scalability

This new module boasts the high processing power required for quick and easy updates. Updates can be easily managed on site to extend the life cycle of your installations.

Icon for the open ecosystem of the MS2 by STid Security

An open ecosystem

Our modules are based on open technologies, standards and recognized public encryption algorithms.
This ambition runs counter to proprietary technologies and enables organizations to keep control of their security policy, in compliance with the recommendations of the French State information systems agency (ANSSI).

Simplified integration in all your applications

Thanks to its built-in antenna and extremely compact dimensions (60 x 35 x 5 mm),
the MS2S Blue can be integrated perfectly in even the most restricted spaces:

The most secure protocol on the market

logo of sscp for the MS2   Readers are compatible with the latest generation of open protocol SSCP (STid Secure Common Protocol). This protocol, recommended by ANSSI, uses data encryption (AES) and two-way “reader-controller” authentication to ensure security before any communication is allowed between the reader and the management system.
