The NFMI chip creates a low-power magnetic field around devices and uses the attractive forces to transfer voice and data 


Using low-power inductive antenna, FreeLinc's Near Field Magnetic Induction (NFMI) chip creates a secure wireless ‘bubble’ around each user - inside the bubble devices instantly connect, and outside they simply cannot be seen. NFMI is the only technology that can be used where secure and reliable wireless Personal Area Network solutions are needed.

increased dynamic reading distances for nfc

FreeLnc’s NFMI provides a magnetic field based communications protocol that offers:

  • Low probability of detection and interception

  • Resistance to jamming and interference

  • Bandwidth efficiency

  • Significantly lower power usage

FreeLinc’s NFMI offers precise geolocation and geofencing capabilities creating powerful layers of security.


FreeLinc’s NFMI is unaffected by water, allowing communications underwater and with deeply implanted medical devices.


FreeLinc’s NFMI can dramatically increase the dynamic reading distances for NFC, thus leveraging the growing NFC infrastructure.



FreeLinc’s NFMI technology solves the security and reliability problems for Bluetooth, the reading distance problems for NFC, and can simply be added to the communications chip to work cooperatively with Bluetooth and NFC, or be deployed as a stand-alone solution.

Over 2,500 U.S. Government and Public Safety agencies use legacy FreeLinc products, including the FBI and the Secret Service.

FreeLinc owns over 40 patents governing the use of NFMI in the data transfer and wireless communications space including important factors such as antenna diversity, intelligent antenna selection, auto tuning, spatial location and orientation detection, and proximity based connectivity among others.
