NFC - Coming soon to Android Froyo + MicroSD Slots

I got to test a NFC conversion for Samsung Galaxy S. It is using a Micro SD Card that transmit radio frequency, equiped with 4Gb internal memory (to replace your current SD Card) and a back cover that has an antenna built in to amplify the radio signal. 

So basically, NFC made possible in any Android phone today... (iPhone5 still thinking of launching it with NFC capability or not)

In short, good news to Android brothers, we can have NFC offshelf to use with our existing phone if needed. 


-------------------------


Geeky term : Near field communication, or NFC, is a set of short-range wireless technologies, typically requiring a distance of 4 cm or less. NFC operates at 13.56 MHz and at rates ranging from 106 kbit/s to 848 kbit/s


Well, basically, it is like Touch and Go. However, Touch and Go is Passive NFC with very limited usage. Just passing some info around when detected. An initiator needs to detect and power the passive NFC.


Active NFC are both powered. It can connect as peer to peer and do more than just receiving some bunch of binary data. It can be used for file transfer, business card transfer and even sending and receiving photos. 


Usage ? Mostly these days, people will use it for :
- Payment 
- Identity 
- Electronic Keys
- Social Networking
- Gaming in near future?
