What is NFC?

Near Field Communication (NFC) is a short -range wireless communication technology found in mobile phones, credit cards, inputs and other devices. The distances are limited to just a few inches to ensure privacy and reduce energy consumption. Small or no settings and NFC devices can work in different modes. This technology is expected to have a great impact on the industry's mobile phones and can turn phones into virtual wallets that store identity and payment information.

Unlike many other wireless communication technologies, the NFC has been designed to have a very limited range. In general, equipment that supports this technology must be approximately 1-1/2 inches (4 cm) apart, although in some cases longer distances can be supported. This limited range provides some safety against eavesdropping and handling because any attack would also have to take place from several centimeterspotential victims. Less also uses power transmission through the distance class, important features in mobile batteries.

Communication above NFC takes place between two devices and requires small or no settings. The "initiator" device sends radio waves to start communication with the "target" device that listens to incoming signals. The connection can be either active, ie both devices emit radio waves or passive, which means that one device is powered by radio emissions of another device. Once the link is bound, the data can be transferred in the reader/writer mode in which one device writes the data to another or in Peer-to-peer mode on which the device they exchange data.

NFC technology is expected to have a big impact on the industry's mobile phones. Mobile phones equipped with technology can be used as "virtual wallet" and can potentially replace debit and creditCards, rewards, tickets and travel cards. The first PHO-S support of NFCNES was released in 2007 and pilot programs in Europe and Asia allowed consumers to make payments, use mass transit systems, and even start commercial flights using their phones. More advanced applications are also possible, and some are this technology that powered everything from interactive advertising to wireless files.

In addition to the mobile phones industry, NFC technology could be used on credit cards, waist, inventory tracking systems, tickets and advertising. In the US and other countries, some retailers already have payment terminals compatible with NFC, which allow consumers to buy goods by waving a credit or debit card in front of the device. Consumer electronics devices can also include technology for different purposes, from wirelessly printing photos from digital camera to replacement information OK Set a secure connection Bluetooth® or wifi.
