1. SHORT DISTANCE WIRELESS COMMUNICATION
NEAR FIELD COMMUNICATION (NFC)

2. HISTORY Wireless telegraph was invented by Marconi
Initially L-C tuned circuit oscillator transmitter and super regenerative receiver formed the system
one of the most important technologies for intuitive, simple and safe communication

3. Introduction to NFC
It evolved from the combination of existing contactless technologies
NFC can communicate with existing smart cards and reader, as well as NFC device
Now a days it is generally implemented into mobile phones

4. How NFC WORKS
NFC communicates via magnetic field induction through loop antennas
Operating range MHz
Working distance: up to 20 cm
It has two operating modes:
1. Passive communication modes
2. Active communication modes

5. NFC hardware and software
The most important component is NFC controller IC with an antenna
Second important component is secure Element(SE)
An application is written inside Java J2ME compliant mobile phone

6. Characteristics of NFC
RF power output of several microwatts up to 100 milliwatts.
Principally indoor operation.
Omni- directional built in antennas.
Simple construction and relatively low price .
Battery-operated transmitter and receiver.
