Definition of 'Near Field Communication (NFC)'

Near Field Communication (NFC) is a set of standards for short-range wireless communication between devices. It works by using magnetic induction to transfer data between two devices when they are brought within a few centimeters of each other.

NFC is used in a variety of applications, including mobile payments, ticketing, and access control. In mobile payments, NFC allows users to make payments by simply tapping their phone against a payment terminal. This is a more secure and convenient way to pay than using a credit card or cash, and it is becoming increasingly popular.

NFC is also used in ticketing, such as for public transportation and events. In this application, NFC tags are embedded in tickets or passes, and users can tap their phone against the tag to validate their ticket. This is a more convenient way to validate tickets than using a physical ticket, and it can also help to prevent fraud.

NFC is also used in access control, such as for unlocking doors or entering buildings. In this application, NFC tags are embedded in cards or fobs, and users can tap their card or fob against a reader to gain access. This is a more secure way to control access than using a key or code, and it can also help to track who has entered a building.

NFC is a relatively new technology, but it is quickly gaining popularity. It is a secure, convenient, and versatile technology that has the potential to revolutionize a variety of industries.

Here are some additional details about NFC:

* NFC is a contactless technology, which means that there is no need for physical contact between the two devices.
* NFC is a short-range technology, with a range of up to 10 centimeters.
* NFC is a low-power technology, which means that it does not require a lot of battery power.
* NFC is a secure technology, with built-in security features such as encryption and authentication.

NFC is a promising technology with a wide range of potential applications. As NFC devices become more common, we can expect to see NFC used in more and more applications.
