What is Near Field Communication?



What is Near Field Communication? Some users do not know the answer, but it is simple to understand. Near Field Communication is very commonly used these days. Most modern phone and data devices use it. All short range wireless connectivity uses it also. Here are the basics.

NFC or Near Field Communication is a particular set of wireless technologies that have of short range requirements for distance and connectivity. Generally these would be less than 4 cm. It runs at ranges of 106 - 424 kbit/s, on an ISO/IEC 18000-3 air-interface and operating at 13.56?MHz. Most device platforms use standardized technologies with ECMA-340 or ISO/IEC 18092.

Although still growing NFC technology is not new, just the usage volume globally. The ability to use near field devices will inevitably lead to greater revolutions in the industry, most people are lucky enough to have lived to see it. It represents a wide range of companies, businesses and industries, groups like the NFC Forum and the GSM Association are among these.

Near Field Communication will allow for quick transactions, exchanges of information and wireless connectivity between any pair of devices. All they need is to be in proximity of each other. It is a growing industry in communications and becoming used predominantly in the United States. If users have their banking and credit information stored to their NFC smartphone or mobile device, the can tap or magic wand activate purchases on the user end. It is not necessary to have an actual credit card on the user. This can be a convenience or a security risk, the user must weigh this with NFC devices. Being informed and educated on how to use your device is the best way to be.

NFC employs two different codlings to transfer data, passive and active. NFC has targets and initiators. Targets are passive, initiators are active. The target is always powered by the RF field actively generated by the imitator. Things that do not require batteries can be targeted. So can stickers, key fobs and tags. NFC tags contain data is usually read only or rewriteable. NFC devices can communicate peer-to-peer, if both are powered. Near Field Communication uses magnetic induction with near field loop antennas. NFC devices can transmit and receive data simultaneously. The wonders of Near Field Communications are expanding everyday, soon these devices will become globally accepted like television or radio in past decades.

The majority of smartphones being marketed publicly have NFC chips embedded. These chips send near field or short range transmissions of encrypted information. These are commonly used with modern retail cash registers. More and more devices are being adapted to use NFC applications. As with all current proximity technologies, the distance and transfer rates are likely to increase in the near future. So by keeping up with these technologies, users will be able to access their expansion as it happens historically. This are some of many great things coming from NFC technology.
