Well I was looking into Potential NFC Benefits or use cases which we can use it for. Few of the first primary target is the Financial Sector. Most of the usecase are about Mobile Money. (like the Google Wallet). First I was very much interested/excited in the Mobile Money kind proposition, slowly came to realization that it has too many overheads. You need to sync up with a BANK, then Involve Retailers, etc etc too much of hassle if you take the INDIAN Market. Here are few things which I think can be used other than Financial Sector. - NFC card for getting into your hotel room.  - NFC enabled Phone as your car keys.  - your business card. - your public transportation. - concert, sports or other event tickets. - your boarding pass for getting on a plane.  - coupons and Many more.
