What is NFC? Near Field Communication.

Chances are, you've seen the NFC logo on a product or two and wondered what it meant. NFC, or Near Field Communication, is a type of wireless communication that allows for two devices to exchange data when they are in close proximity to each other 

You may have also seen NFC tags, which store data that can be read by an NFC-enabled device. For example, an NFC tag could be programmed with information (data) like a URL so that when you tap your phone against the tag, your phone's browser will automatically open the URL. Or, an NFC tag could be programmed with contact information, so tapping your phone against the tag would add the contact to your address book. Scard helps keep your contact information organized and up-to-date while also providing extra features like the ability to link directly to your Scard profile.

NFC is a Radio-Frequency Identification (RFID) technology branch and has been around since 2002. However, it has only recently started to gain mainstream adoption. In this article, we'll explore NFC in more detail and answer common questions about this technology.

 

How Does NFC Work? 

NFC operates on the principle of inductive coupling. This means that power is transferred between the two devices using magnetic fields. One device functions as an NFC reader/writer, and the other functions as an NFC tag. The reader/writer can read and write data to the tag. Data can also be exchanged between two NFC-enabled devices if they are placed close to each other (usually no more than 4 cm apart though the actual distance is 10cm max)

The reader/writer generates a magnetic field to communicate using inductive coupling. This field provides the tag power and transmits data between the two devices. The amount of power that can be transmitted using inductive coupling is very limited, which is why NFC tags are typically very small (they don't need a large battery) 

 

How & where to buy it?

To purchase a Scard Smart Card, Sticker + NFC tag, or Smart Ring, you must create an account with us, complete your profile, and go to the Scard Shop to acquire it. It will be tailored specifically to your profile, so you cannot purchase it before having an account on Scard.

The cards you find at the exhibition or shops for sale are not personalised. Those can be purchased before creating an account on Scard because it includes a function that links your profile to your account after registration.
