NFC brief
• Near field communication (NFC) is a set of standards for smartphones and
similar devices to establish radio communication with each other by touching
them together or bringing them into close proximity, usually no more than a
few centimetres.
• NFC builds upon 13.56MHz Radio-frequency identification (RFID) systems by
allowing two-way communication between endpoints.
• The standards include ISO/IEC 18092[4] and those defined by the NFC
Forum, which was founded in 2004 by Nokia, Philips and Sony, and now has
more than 160 members.
• Comparison with BT:

NFC mode
• 3 modes can be supported by NFC”:
• Reader mode: Multi-protocols(ISO/IEC 14443, JIS X 6319-4/Felica, ISO/IEC 15693)
• Pier-to-Pier mode: NFCIP-1. NFCIP-2(ISO/IEC 18092, ISO/IEC 21481)
• Card emulation(Secure Element): EMVCo/ISO/IEC 14443, JIS X 6319-4/Felica)
Do you really need all of them(a reader-writer, lower data rate P2P, payment) at one?

Create a unique password for each M24LR64 produced
• Each M24LR64 comes with a Unique 64-bit IDentifier (UID)
• Factory programmed and locked by ST
• 64-bit UID can be used to compute a password different for each
M24LR64 produced!
MyPassword = MyFunction (UID)
UID = 00 01 02 03 04 05 06h
Pwd = 06 00 01 02 03 04 05h
UID = 70 71 72 73 74 75 76h
Pwd = 76 70 71 72 73 74 75h
