Compact Integration for Seamless Deployment
The ultra-compact design of the MS2S Blue simplifies integration into a wide variety of devices, from kiosks and terminals to industrial control systems. Its integrated antenna minimizes the need for external components, reducing installation complexity and costs. Designed for quick and reliable deployment, this module excels in scenarios where space is limited but high-security identification is essential.

Intuitive Identification, Better User Experience
The module supports STid Mobile ID® user-friendly solution and offers six unique user interaction modes for intuitive contactless identification:
• Card mode: present your smartphone or wearable to the reader like a conventional access card.
• Slide mode: your hand becomes your access card.
• Tap Tap mode: tap tap the smartphone in your pocket to gain access.
• Remote mode: use the “remote button” to conveniently access car parks or other vehicle entrances.
• Hands-free mode: simply walk towards the reader without any further action.
• Voice command: use SIRI voice command on your iPhone (iOS) or Apple Watch.

Flexible for Migration and Future-Proof
The module’s dual-frequency support (13.56 MHz and Bluetooth®) ensures compatibility with a broad range of existing credentials while enabling a smooth transition to mobile technologies. Ideal for multi-site or phased migrations, the MS2S Blue can read multiple badge types, allowing organizations to evolve their security systems at their own pace. On-site updates extend the module’s lifecycle, ensuring it stays ahead of emerging needs and standards.

Advanced Security and Encryption Standards
The MS2S Blue module incorporates the latest MIFARE® DESFire® EV3 chip technologies, ensuring robust protection against modern threats:
• Secure Messaging EV2 prevents interleaving and replay attacks.
• Proximity Check safeguards against relay attacks.
Powered by an EAL5+ certified crypto processor, the module supports public encryption standards (3DES, AES, RSA, SHA), delivering peace of mind for organizations with stringent data protection requirements.
