OEM USB PC/SC NFC coupler module (without antenna)

The H512 is a read/write NFC module able to emulate a card and to communicate in a “peer-to-peer” mode.

It interfaces thanks to a USB link with a host (computer or embedded system) supporting PC/SC standard.

The H512 module needs to be associated with one of the SpringCard’s portfolio antennas or a custom-made one, according to your size constraints. The antenna must be balanced.
