Zufällig gelesen: Sparkasse will neue Bezahlkarte forcieren - ähnlich RFID. Alter Hut oder neue Baustelle ?? Info mit Zitat aus Wiki folgt per copy/paste. Ideale QRG für kurze Entfernungen (':shock:')

NFC is a set of short-range wireless technologies, typically requiring a distance of 10 cm or less. NFC operates at 13.56 MHz on ISO/IEC 18000-3 air interface and at rates ranging from 106 kbit/s to 424 kbit/s. NFC always involves an initiator and a target; the initiator actively generates an RF field that can power a passive target.

As with proximity card technology, near-field communication uses magnetic induction between two loop antennas located within each other's near field, effectively forming an air-core transformer. It operates within the globally available and unlicensed radio frequency ISM band of 13.56 MHz. Most of the RF energy is concentrated in the allowed ±7 kHz bandwidth range, but the full spectral envelope may be as wide as 1.8 MHz when using ASK modulation.[33]

NFC - "Nahfunk" 13.56 MHz mit 1,8MHz Bandbreite
Gibt es doch jetzt schon bei den neuen Kreditkarten.
