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