What is Near Field Communication

NFC (Near Field Communication) is an evolution of RFID technology; NFC enables secure wireless connectivity between two devices, with related exchange of data.

NFC technology, applied to a smartphone or a tablet, allows:

  • the exchange of information between two devices using peer-to-peer; it's safe and quick;
  • to make quick and protected payments with mobile phones;
  • to read or write information in NFC Tags.

What are NFC Tags

NFC Tags are tiny integrated circuits with an antenna, usually integrated into stickers, gadgets, assets or smart cards.

On NFC Tags you can write information easily readable (and executable) by NFC devices, like smartphones, tablets, or NFC readers.

To read a Tag, you just have to tap it with your device.

NFC Tags dimensions range from 12 mm to 8-10 cm.

The average Scan range of NFC Tags is about 3-4 cm. It depends on Tag's size (the bigger, the better), on NFC chip (Ntag21x are better) and on NFC reader.

NFC Tags are very similar to a digital memory (less capacious), but they does not require energy supply, because they are directly activated by the magnetic field of NFC device. The available memory, as we said, is limited, but it is not a real limit: just think of the possibility of writing a link to a web page, which can be applied to any object, brochures, flyers, posters, business cards, clothes, product packagings and so on, with free space for creativity.

NFC Tags are similar to QR Codes, but they can contain more information and don't require any applications to work properly.

What kind of information can be written on NFC Tags?

On NFC Tags you can write a lot of types of information. Some of these are for private use:

  • enable/disable Wi -Fi
  • activate/deactivate the Bluetooth
  • activate/deactivate the GPS
  • open/close an application
  • and so on...

Then there are the applications for a public/business use or for marketing use:

  • open a web page
  • download an app
  • open a link to buy a product
  • share a V-Card contact
  • give a "Like" on Facebook
  • follow a Twitter account
  • send an email
  • send an SMS
  • start a phone call
  • check-in on Foursquare
  • and so on...

NFC Tags also have the advantage that you can easily read them using a cheap phone and write them by yourself with a free application (Android, iOS, BlackBerry or Windows).

Every NFC Tag has also an Unique Identification Number (UID), separeted from its memory, so NFC Tags can be used also for access control, tracking or for certificate the authenticity of a product.
