Although NFC is slower than Bluetooth and has a much more limited range, it consumes less power. Additionally, there are no set-up passwords or codes required, as there is with Bluetooth and secure Wi-Fi. For this reason, one of several possibilities for NFC use is for devices to ‘handshake’ as a means of accepting another kind of connection. They would only need to be placed close enough for the NFC to register first, but could then be moved away to normal Bluetooth distances once the connection was established.
These types of extended uses for NFC could be very useful, but contactless payment is what is really hitting the headlines.

When you pay with a phone, you could not only pay, but receive plenty of information digit’ in return like coupons, receipts, loyalty points and warranty programs which could save your time, and your retailers money and resources.
