Just think of all the fun you could have if the iPhone could interact with RFID tags. But you don’t have to wait for Apple for iPhone version 7 for this feature. Nope. You can build your own iPhone compatible RFID reader right now.
Maybe not right now. First you probably have to get through your day at the office and make your way home only to spend a few mundane hours with the family. But maybe in the 35 minutes you have after your last kid goes to bed and the nightly news starts, you could assemble this project.
