Near Field Communication Tags

Near Field Communication (NFC) is a wireless communication technology. NFC allows the transfer of data between two wireless devices that are in close proximity to one another. Near Field Communication is used to make payments by using a cell phone. It avoids using a hard copy of a credit card and is a secure and safe method of making payment. 

Paying for a purchase is not the only use for NFC. MIT has done research into Near Field Communication tags which transfer information when tapped with an NFC enabled wireless device. These tags could give the user information about the item that the tag is located on. NFC enabled devices can scan and read codes similar to QR code readers but can go a step further by taking the info from the original code and transferring it to another NFC enabled device.

When using Near Field Communication devices a tag is scanned that holds unique data. When scanned the tag may launch an action or hold some specific meaning. For example an NFC enabled cell phone could unlock and start an NFC enabled vehicle by scanning the tag on the car. NFC tags can be found in stickers and wristbands and they contain a small microchip. These chips contain small aerials that transfer data when they are touched by a Near Field Communication device.

NFC tags do not require an outside power source. They are powered by their proximity to another NFC device. The amount of data that can be stored on a Near Field Communication tag will depend on what type of tag you are using. These tags can be used for a variety of purposes such as transferring an address to a mobile device or even making a payment using the mobile wallet on your cell phone.

Some people believe that NFC technology will make QR codes, another type of mobile transfer technology, obsolete. The technologies differ from one another in such a way that they will most likely be able to co-exist. QR codes are a free form of data transfer and do not require the user to be as close as NFC users do. Near Field Communication tags are not free. Marketers that are currently using this technology argue that the cost is money well spent.
