NFC near field communication technologies usage in Mobile world in not a new buzz now. Its has been there last
Mobile Money, Mobile
ATM alternate small money transaction
Ticketing: Air/train/concert/sports or any kind.
Access Systems: College/University access Card, NFC posters
What makes NFC hot is its range? interestingly its just 10cm range which unlike other teach looking for more range here lesser range makes it more interesting.
Take a case as example: Think suppose you have a ticket saved into a chip which can transmit data wirelessly to reader..Now if we use Bluetooth : it can read from 10 meter..so moment someone is near to 10 cm to out door of railway station ..it will open door..moreover till he covers this distance it will remain open.. Moreover many people around means door will remain open always…off course that can be controlled programmatically but this is where NFC comes Exactly untill u bring in near to 10 cm range gate will not open.. So automatically tail-gating can reduced….
This precise 10 cm range which makes it interesting and hot…
Components of NFC:
Wireless tag: Active/passive: a small chip surrounded by magnetic coil so when and Electromagnetic waves producing device like Mobile comes closer it generates current and energy enough to power chip attached which can be used to store program,data (text, url, etc.) .
Samsung TecTile target smart Tag market but no vendor supporting it currently:
Samsung with Galaxy S3 launched tech tile coil small tag at rate 3 dollar per tag. But as we tec tiles supported MiFARE chips which non of other vendor like Microsoft, Google Nexus , Blackberry etc does not support only Galaxy S4 have support for it..
Look at top NFC running projects map across the world: click on country an city to know more details of number of NFC projects running in your city/country… (feel sad: only 1 in India :< 😦 ) , 1 in Ireland, 5 in London city alone http://nfctimes.com/nfc-projects
read more details on the link above.
One Project looked interesting to me was : http://www.nfcworld.com/2013/11/27/327121/diamond-circle-turn-nfc-tags-bitcoin-wallets
NFC tags are much widely used across chipset and tag vendor giving fillip to OpenNFC. visit(http://open-nfc.org/wp/).
customize NFC using
1. Besides NFC Adapter available within Andriod API (http://developer.android.com/guide/topics/connectivity/nfc/index.html)
2. Windows Mobile (latest acquisition Nokia’s Lumia NFC API visit: http://developer.nokia.com/Develop/NFC/),
3. Blackberry NFC API http://docs.blackberry.com/en/developers/deliverables/34480/Near_Field_Communication_1631111_11.jsp

The data Exchange Format NFC Data Exchange Format (NDEF) introduced here in :
In short NDEF message have NDEF record and payload. Start header bit MB message begin and End at ME message End.IL is identification CF chunked fragment and Type field defined in RTD specifications TNF.
Competing NFC technologies:
QRCodes: use optical not electromagmatic field.
iButton: unlike NFC contactless is contact technology.
Touch a Tag: RFID based Tag.
