– Step by step -- How NFC works
How NFC works
- NFC means “Near Field Communication” or near field communication in Spanish. This is a short-range wireless communication system that allows two devices to communicate when they are a few centimeters apart.
- NFC-enabled devices have a built-in chip that acts as an antenna, allowing a connection to be established with another compatible device. These devices can be cell phones, tablets, credit cards, key chains, and other electronic devices.
- To use NFC, devices must be enabled and configured for this feature. This usually involves turning on the NFC option in the device settings.
- Once the devices are close to each other and the NFC feature is enabled, they can exchange data quickly and securely. This can be used to make payments, transfer files, share contact information, among other uses.
- In addition to data transfer, NFC can also be used to activate commands or functions on compatible devices, such as opening a door with a mobile phone or activating a Bluetooth mode on a speaker. This versatility has made NFC increasingly popular in different applications.
