LEGIC SM-6310 Programmable Security Module

IoT Edge Processor with RFID,
Bluetooth® and Secure Element

Intelligent security and contactless interaction for connected infrastructure and IoT devices

With application code and cryptographic keys stored in Secure Element (SE), the SM-6310 is ideal for compact, low-power, contactless applications requiring secure user authentication and credential management. It supports smartcards and iOS / Android smartphone apps based on LEGIC Connect.


  • ARM® Cortex® Core with 128 KB programmable flash memory stored in EAL5+ Secure Element ("Custom Code")
  • Supports RFID, NFC and Bluetooth 5 for smartphone, smartcard, fob, tag and label based applications
  • Compatible with LEGIC advant, neon, NXP MIFARE*, HID iCLASS*, LEGIC MTSC and Connect
  • High security based on AES-128/256 encryption, hardware Root-of-Trust
