Category: NFC
NFC bedeutet „Near Field Communication“ und existiert schon länger auf dem Markt. Man versteht darunter die kontaktlose Datenübertragung, die sich die Radio Frequenz Identification (RFID-) Technologie zu Nutze macht. Die weltweit standardisierte Frequenz beträgt 13.56 MHz. Es sind Übertragungsreichweiten von ca. fünf bis zehn Zentimetern möglich.
