What is NFC: Tags, Chips & Applications

NFC (Near Field Communication) on a phone is a short range wireless technology that enables secure data exchange between nearby devices. Commonly used for contactless payments, device pairing, digital access control and information sharing, NFC provides fast, convenient and secure wireless interactions through smartphones.

NFC utilizes a tag or chip within the mobile phone to enable short range wireless communication.
This technology facilitates communication between wireless devices over a very short distance (approximately 4 inches). Smartphones equipped with NFC tags can exchange information with a simple tap.

Applications of NFC

Beyond simple data exchange, NFC has a variety of applications, including:

• Online payments
• E-ticket booking
