What’s an NFC tag?


During the recently held #TweetupSL, diIGT gave away bunch of gifts to the award winners. Among them was something known as an ‘NFC tag’. Some already knew what it was and some did not. So we thought of explaining what NFC and what these so called NFC tags have in store for us.

Imagine a world where the world sees a physical version of the web, a one in which everything having a digital signature. With the new developments in the field of NFC tags, it may seem possible.

NFC (Near Field Communication) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them to a close proximity.

An NFC tag is an unpowered chip which is called a “tag”.

Similar to NFC tags includes RFID (Radio Frequency Identification). NFC is a lot like RFID, but the difference between them is that RFID works when used from a distance, where NFC tags work in a close proximity. NFC tags most likely appear in products where only bits of digitized information might come handy. It is speculative that NFC tags one day, could be used as commonplace as bar codes.

NFC tags could come handy in many ways. For an example, it could be used as a menu in a restaurant, where all the meals published there could be instantly transferred to the customer’s cell phone including all its prices, nutritional facts and whatnot. The uses of NFC tags could practically be endless.

NFC tags could also work as navigators. That is, when the following tags are brought near a smartphone with NFC capabilities, the browser in the smartphone will automatically be navigated in to this very website.

A NFC tag has no power source. Thus, it makes them passive.  Instead, they literally draw power from the device that reads them. Magnetic induction does the trick here.

A NFC tag has a bit of a storage memory, along with a minute radio chip attached to an antenna.

It is speculated that in recent future the NFC tags could be everywhere, letting you tap your way across a newly digitized world.
