How It Works ?

6. 9/12/2015 N F C 4
• NFC devices communicate via magnetic
field induction, where two loop antennas
are located within each other's near field,
effectively forming an air-core
transformer.
• The reader continuously generates an RF
carrier sine wave (at 13.56 MHz),
watching always for modulation to occur.
Detected modulation of the field would
indicate the presence of a tag.
