NFC (Near Field Communication) is a kind of contactless radio communication between cell phones, tablets and similar gadgets. Usually, the gadgets have to be at close proximity with one another for it to operate. It's a technology that was founded by Nokia, Philips and Sony in 2004, which came up with a set of standards to cover data exchange formats and communication methods, promote it, and certify device conformity.
Radio Frequency Identification (RFID) is utilized in NFC in which a reader sends radio waves to an electronic tag. The gadgets must be at a distance of under 4cm to operate. Normally, it runs using air interface of ISO/IEC 1800-3 at 13.56 MHz at 106-424 kbit/s rates range. There has to be an initiator and a target with the initiator generating a radio frequency field, which powers the inactive target. Thus stickers, tags or cards that are not powered can be targets. The first cellular phone to use the technology was Nokia 6131 in 2006.
It has broad applications such as payment systems, sharing details, in transportation and health care among others. In contactless payment systems, the user typically uses his/her NFC compatible device to make payments in a manner similar to that found in electronic ticket smartcards or debit cards. The user does not have to carry his/her credit card around because the user swipes his/her device at the card reader to make payments. It's a system that has become popular and is currently getting used in cinemas and in public transportation systems. In health care, doctors can conveniently keep track of the medicines administered to their patients and recommendations in real time thanks to this technology. This ensures that no unsuitable medicine is given to the patients.
This technology may also be used in social network. This technology can be used to share photographs, files, contacts and play multiplayer games. In a similar manner people can update their location status without having to log in to the Internet. For businesses, this allows employers to keep track of their workers who record their time spent on breaks and their locations as well. It's also possible to establish Wi-Fi and Bluetooth connections to make file transfers or pair with Bluetooth audio system or headsets. This rule is also utilized to configure Wi-Fi networks. Some of the most practical current uses of near field communication are starting apps, performing commands, creating and sending messages and changing mobile phone settings. This is because they aren't dependent on a specific company but only need one to have an NFC tag and Near Field Communication compatible mobile phone.
On the other hand, the possibilities of the technology allow a client to get as much details as he/she might want about a given stocked product which has an NFC tag on it by just waving his/her mobile phone over the said product. Moreover, the client will not have the trouble of having left the wallet at home since all the details required to shop will be in his mobile phone. The introduction of Google Wallet allows for the storage of store loyalty and bank card details in what is considered a virtual wallet. This can be used to make transactions, which further promotes business.
