Understanding NFC: Tags, Chips, and Applications

This article explains NFC (Near Field Communication) technology found in mobile phones, detailing its uses and features.

NFC utilizes a tag or chip within the mobile phone to enable short-range wireless communication. NFC stands for Near Field 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
