NFC

• NFC (Near Field Communication)
• 13.56 MHz
• 20 cm
• 106, 212, 424 Kbps
• Response time 0.1-0.3 Sec
• ISO / IEC 18092 (NFCIP-1) - NFC Spec.
• ISO / IEC 21481 (NFCIP-2) - fast track process
• ISO/IEC 18092 (NFCIP-1), ISO/IEC 14443(PCD) and
  ISO/IEC 15693 (VCD)standards all specify 13,56
  MHz as their working frequency, they specify
  distinct communication modes.
• This NFCIP-2 Standard specifies the mechanism to
  detect and select one communication mode out of
  those three possible communication modes.
