The idea of paying for groceries or a tank of fuel simply by tapping one small electronic device to another seemed like science fiction not too long ago. This technology is now commonplace. Near Field Communication (NFC) technology and smart tags that work with NFC make this possible.

NFC works like RFID, not a fundamentally disruptive technology, just a more personal type of wireless. RFID can be used over long distances, while NFC readers have a maximum operating range of about 4 inches (10 cm), so NFC is not suitable for inventory tracking, but it comes in handy for quickly exchanging small amounts of digitized information.

You can call NFC tag smart tag, information tag.

What is NFC tag?

Near-field communication (NFC) tags are an up-close-and-personal type of wireless radio communication.

What are NFC tag used for?

NFC tags are used in applications where the quick exchange of a few bits of digitized information comes in handy. One of the more commonly known ways they're used are in smartphones to make mobile payments; NFC tags are the reason some phones can simply be tapped to a reader to pay for something. When it comes to potential uses for NFC tag, there really are no limits.Can also be used in retail, healthcare industries.
