NFC is one of the latest wireless
communication technologies. As a short-range wireless connectivity technology,
NFC offers safe — yet simple and intuitive — communication between electronic
devices. Users of NFC-enabled devices can simply point or touch their devices
to other NFC-enabled elements in the environment to communicate with them,
making application and data usage easy and convenient.
With NFC technology, communication
occurs when an NFC-compatible device is brought within a few centimeters of
another NFC device or an NFC tag. The big advantage of the short transmission
range is that it inhibits eavesdropping on NFC-enabled transactions. NFC
technology opens up exciting new usage scenarios for mobile devices.
Near Field Communication (NFC) is a
technology for contactless short-range communication. Based on the Radio
Frequency Identification (RFID), it uses magnetic field induction to enable
communication between electronic devices. The number of short-range
applications for NFC technology is growing continuously, appearing in all areas
of life. Especially the use in conjunction with mobile phones offers great
opportunities.
One of the main goals of NFC technology
has been to make the benefits of short-range contactless communications
available to consumers globally. The existing radio frequency (RF) technology
base has so far been driven by various business needs, such as logistics and
item tracking. While the technology behind NFC is found in existing
applications, there has been a shift in focus — most notably, in how the
technology is used and what it offers to consumers.
With just a point or a touch, NFC
enables effortless use of the devices and gadgets we use daily. Here are some
examples of what a user can do with an NFC mobile phone in an NFC-enabled
environment:
• Download music or video from a smart
poster.
• Exchange business cards with another
phone.
• Pay bus or train fare.
• Print an image on a printer.
• Use a point-of-sale terminal to pay for a
purchase, the same way as with a standard contactless credit card.
• Pair two Bluetooth devices.
