LEGIC SM-6300 Security Module
RFID, Bluetooth® and Secure
Element in one Module
More security for your IoT communication and your reader interactions
Thanks to the embedded certified secure element (SE), the SM-6300 is ideal for applications requiring a high level of security. The security module not only supports all globally relevant smartcard technologies such as LEGIC prime and advant, MIFARE* and HID iCLASS*, but also applications implementing LEGIC neon files.

- Reads all globally relevant RFID standards
- Compatible with LEGIC advant, neon, NXP MIFARE*, HID iCLASS*, LEGIC MTSC and Connect
- Fulfills high security requirements based on an integrated secure element
