NFC: What's it? & How it's work?

NFC - Near Field Communication is a hardware for smartphones and similar devices like some laptops to establish radio communication with each other by touching them together or bringing them into close proximity. Communications is also possible between a NFC device and an unpowered NFC chip, called a "Tag".

 

Nowadays, most of the new smartphones has been equipped with NFC hardware to make all the things. However, the people, who equipped with NFC smartphones haven’t used the NFC capabilities. NFC might be the future for payments, security keys, boarding passes and all in all.

Establishing a NFC connection is easy, by touching NFC equipped devices together. If you've two NFC equipped smartphones, then they should be touched together back to back. And if you have the tag of NFC, then you would have to touch the back of the NFC equipped smartphone with the NFC tag. The hardware NFC is included in a wide range of devices, which supports Android and Windows platform as well. 

Mobile Payments through NFC is similar as tap-to-pay contactless payment. NFC equipped phones can be touched or waved over NFC enabled payment terminal, to pay, as you wish, instead of using a credit card. 

 

Some car parking lots in San Francisco has equipped with NFC parking meters that allow the people to pay parking taxes by tapping NFC equipped phone against the parking meters. India is implementing NFC based transactions in Box Offices for ticketing purposes. Germany, Austria, Finland, New Zealand and Italy have trialed NFC ticketing systems for public transport.

 

Transferring Data over Bluetooth and Wi-Fi is competent between two phones, if both were equipped with NFC. NFC offers a low speed connection with simple setup. Android phones has a software named Android Beam, which uses NFC technology, to share web pages, contacts, photos, video and other type of information and establish Bluetooth connections, too, for doing file transfer. By touching the two phones back to back, the content being viewed on one device then will be forwarded to other. The same principle could also be applied to Wi-Fi networks. Social Networks also be accessed in NFC technology such as sharing contacts, photos, videos or files.

NFC Tags are like stickers, which can be programed by NFC Apps. Anyone can buy NFC Tags, which are cheaper, and able to configure the tasks such as changing of phone settings, creating text then sent or executing any number of commands that the smartphone comes with NFC Tag. 

For instance, you need the smartphone should always be in silent mode when you go to sleep. Instead of doing this manually every night, you could arrange a NFC tag at your bedside table and place the phone onto the NFC tag then the phone will perform an action of configuration, such as automatically enabling to silent mode.

To access Wi-Fi through a NFC tag is simple and the NFC tag should be configured SSID and Passphrase of the related Wi-Fi network. When you need to access Wi-Fi on your phone, then touch the phone onto the NFC tag and log on, rather keying all the details manually.
