It's actually not very flexible. I've seen field trials of this. It is an interesting concept but not very implementable. You could do the same data transfer by having the phone display a barcode and use a barcode scanner. They claim that outfitting an existing system with an NFC reader costs $100 to $800. Which is not true. An NFC dongle is under $20. They are looking at costs of NFC stand alone terminals (w/ LCD display, etc.) and that high cost is due to secure element and certifications those have to go through to work w/ Visa/Mastercard networks. It is an interesting technology and has its uses but not as an NFC replacement.
