..and sorry…If you have to ask a blog about an idea to start a business, don’t bother…Because if someone really had a good idea to execute on (without morale conflicts) that would be worth there time, they wouldn’t be sharing it on a blog 🙂
Personally, I’ve started experimenting with NFC on Gingerbread releases on my personal time, but I think we’re ways away from anything meaningful here in the States.
