NFC, which is the short kind of Near Field Communication is a kind of contactless radio communication between cell phones and comparable gadgets. In order to operate, these gadgets have to be close to one another. It’s a technology that was developed by Nokia, Philips and Sony in 2004, which came up with a set of specifications to cover data exchange formats and communication practices, publicize it, and certify device conformity.
Radio Frequency Identification (RFID) is used in NFC in which a reader transmits radio waves to an electronic tag. The gadgets should be at a distance of under 4cm to operate. Normally, it operates on air interface of ISO/IEC 1800-3 at 13.56 MHz at 106-424 kbit/s rates range. There should be an initiator and a target with the initiator producing a radio frequency field, which powers the inactive target. Therefore, the target can be stickers, tags or cards that are not powered. The Nokia 6131 was the first mobile phone to ever make use of this technology.
It has extensive applications such as payment systems, sharing information, in transportation and medical care among others. In contactless payment systems, the user typically uses his/her NFC compatible device to make payments in a manner comparable to that used in digital ticket smartcards or credit cards. The user doesn’t 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 presently being employed in cinemas and in public transportation systems. In health care, doctors can easily monitor the medicines given to their patients and recommendations in real time due to this technology. This guarantees that no unsuitable medicine is given to the patients.
This technology can also be used in social media. This technology may 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 companies, this allows employers to monitor their workers who record their time spent on breaks and their locations also. It’s also possible to set up Wi-Fi and Bluetooth connections to make file transfers or pair with Bluetooth audio system or headphones. This rule is also used in configuring to a Wi-Fi network. Some of the most practical present uses of Near Field Communication are starting apps, executing commands, creating and sending messages and changing smartphone settings. This is because they aren’t dependent on a particular company but they only require one to have an NFC tag and near field communication compatible device.
On the other hand, the possibilities of the technology allow a client to get as much information as he/she may want about a given stocked product which has an NFC tag on it by simply waving his/her smartphone over the said product. Furthermore, the client will not have the problem of having left the wallet at home given that all the information required to shop will be in his smartphone. The introduction of Google Wallet allows for the storage of store loyalty and credit card information in what is considered a virtual wallet. This may be used to make transactions, which further promotes business.
