9. Why Choice?
省電 :
1) RX: 27 mA, TX: 27mA
2) Wide supply voltage range (2.0V - 3.6V)
3) Microcontroller running at 32 MHz
適合無線感測網路 (WSN) 、物聯網 (The
internet of thing)
使用 8051 Microcontroller

37. RFID and NFC
NFC is just an extension to RFID technology
RFID is capable of accepting and transmitting
beyond a few meters while NFC is restricted
to within 4 inches
RFID has a wide range of uses while NFC is
usually used in cases where security is needed
