What is an NFC Card?

NFC stands for Near Field Communication, a short-range wireless technology that allows devices to exchange information when they are placed close together, typically within 4 centimeters.
 
NFC technology is widely used in many everyday applications such as:
Contactless payments   Contactless payments
Digital business cards   Digital business cards
 
Smart access systems   Smart access systems
 
Hotel key cards   Hotel key cards
Public transportation cards   Public transportation cards
 
An NFC business card contains a small embedded chip that stores a digital link or profile. When tapped against a smartphone with NFC enabled, the phone automatically opens the stored information, allowing the user to view contact details or other digital content instantly. Because of its simplicity and speed, NFC technology is transforming the way professionals exchange information.
 

Are NFC Cards Secure?

One of the biggest concerns people have is whether NFC cards can access private data on their phones. The good news is that NFC cards cannot access personal data from a device.

NFC business cards work in a one-way communication process. The card simply sends the information that has been programmed into it, such as a link to a digital profile. It does not read or extract information from the smartphone that taps it.
 
This means that tapping an NFC card does not expose:
