Face recognition and acoustic NFC based access control system
MAX78000 Feather Board
Face recognition with the camera available on the board and MIC with speaker out for acoustic NFC development for an access control system solution.
An OFDM based acoustic Software Defined Radio (SDR) to transmit data. Acoustic NFC has to overcome several challenges inherent in the Acoustic domain,
Frequency selective speaker/microphone characteristics due to electromechanical conversion
Large multipath or echos
Ambient noise sources
This Solution will solve these problems in order to make acoustic NFC communication practical.
