It is not yet a widely used technology, but the number of near field communication (NFC) smartphones is growing. The technology, which can transmit over 4cm distances, allows two devices to exchange information.
NFC has been around for years, but it has been held back by a lack of enabled handsets. One of its current uses is in 'contactless payment' bank cards, where customers pay for goods by tapping the terminal, rather than entering a PIN.
NFC used in this way can also give people different access levels, reducing the cost of identity cards. "Equally, this can be used for access to data," Heaphy adds. "And these things can be updated over the air."
The move to NFC is only just beginning, and when it steps up further, the technology could make a huge difference to many firms. It's something that's easy to try out, using the NFC tags from Amazon, before consulting a specialist about expanding out.
Meanwhile, as the area continues to grow, off the shelf services should soon become readily available. "NFC will be here sooner rather than later," Heaphy says.
