NFC stands for Near Field Communication, a short-range wireless technology that allows devices to exchange data over a very short distance, typically within 4cm. It’s commonly used for contactless payments, pairing devices, and exchanging small amounts of data.Â
Here’s a more detailed explanation:
What it is:
-
- NFC is a short-range wireless communication technology that uses radio waves to exchange data between devices.Â
- It operates at a frequency of 13.56 MHz.Â
- NFC is a short-range wireless communication technology that uses radio waves to exchange data between devices.Â
- The maximum range is typically 4cm (or less).Â
- It requires devices to be in close proximity to each other for communication.Â
How it works:
- NFC uses radio waves to transmit data between two devices.Â
- The devices are typically a phone or a contactless card.Â
- Data is exchanged when the two devices are in close proximity.Â
Uses of NFC:Â
- Contactless payments:Â Using NFC to pay for goods and services with a smartphone or wearable.Â
- Pairing devices:Â Quickly connecting Bluetooth devices or other wireless devices.Â
- Data exchange:Â Sharing small amounts of data like contacts or photos between devices.Â
- Access control:Â Using NFC for keyless entry to buildings or vehicles.Â
- Public transportation:Â Using NFC-enabled cards or mobile apps for public transportation access.Â
- Gaming:Â Using NFC tags like Amiibo for Nintendo devices to interact with games.Â
