What is NFC?

NFC (Near Field Communication) is a wireless data transmission technology that allows data to be exchanged over short distances (usually within 4 centimeters).

How NFC works

NFC uses electromagnetic induction and radio waves to transmit data between devices. When two NFC-enabled devices come into close proximity, they establish a secure connection and exchange data without pairing or establishing a network connection.

Uses of NFC

Common uses of NFC on mobile phones include:

• Mobile payment: Using NFC Contactless payments in shops and restaurants.
• Access Control: Unlock doors and enter buildings via NFC.
• Information sharing: Quickly exchange contacts, files and links through the "peer-to-peer" function.
• Read tag: Read the information contained in an NFC tag or smart poster, such as a product description or website address.
• Personalization: Trigger specific phone settings or actions, such as turning on wireless networks or adjusting the volume.
• Pairing devices: Conveniently pair with Bluetooth speakers, headphones, and other devices via NFC.

How to use NFC

To use NFC, your phone must support the NFC function. Typically, the NFC antenna is located on the top or bottom of the back of the phone. To use NFC, follow these steps:

1. Make sure your phone has NFC enabled.
2. Put another NFC-enabled device close to your phone.
3. Follow the on-screen prompts to complete the data transfer or perform the required operation.

Advantages of NFC

NFC technology has the following advantages:

• Convenience: No pairing required or network connection to transfer data easily and quickly.
• Security: NFC connections are secure and encrypted, helping to protect data from unauthorized access.
• Wide Applications: NFC is widely adopted in various applications such as mobile payment, access control and information sharing.
