NFC
NFC (Near Field Communication) is a short-range wireless technology that allows smartphones to exchange data when placed close to another device.
It is commonly used for contactless payments and quick device connections.
How it works
NFC works through radio signals over a very short distance, usually a few centimeters. When two compatible devices are placed close together, they create a wireless connection.
One device sends small amounts of data to the other, such as payment information or pairing instructions.
Why it is important
- It enables contactless payments.
- It allows quick pairing with devices like headphones.
- It supports digital tickets and access cards.
- It works quickly and does not require internet access.
Simple example
NFC works like tapping a card on a payment terminal — the connection happens instantly when the devices are close.
