What is Bluetooth NFC? NFC stands for “Near Field Communication”. It’s a technology that, like Bluetooth, is used for the primary task of transferring data over short distances. NFC is based on the technology called RFID, also known as “Radio Frequency Identification”. In 2003, NFC was approved as an ISO/IEC standard.
What is the difference between NFC and Wi-Fi?
NFC can read RFID chips but RFID chips can’t talk back to the reader. Wifi is a spread-spectrum (it switches frequencies really fast while communicating to avoid interference and better share frequencies with other things) technology which allows medium range communication used for packet and data routing.
What is an NFC fee?
