How To Turn On NFC On iPhone

NFC, the short form for Near Field Communication, is a short-range wireless communication technology that enables two NFC-enabled devices (like your mobile phone and your laptop) to exchange data.

Unlike other communication technologies which can work even when the devices are kept meters apart, NFC doesn’t work like that. The range of NFC is just 4 centimeters and to connect two devices using NFC, you will have to bring them within the aforementioned distance.

The technology that works behind NFC is RFID (radio-frequency identification). But, unlike RFID which consumes more battery power and works in a large range, NFC uses negligible power to function and works in a very small field.

And, because NFC operates for a very small range, this makes it an ideal choice to use this tech for crucial and confidential information, such as access control, payments, etc.

NFC works by creating a magnetic field between two devices. When a device with an NFC antenna is brought within range of another device with an NFC antenna, the magnetic field causes the second device to turn on its NFC receiver. The two devices then communicate with each other using radio waves.

Applications of NFC

NFC can be used for a variety of applications, including:

Mobile Payments: 

NFC-enabled smartphones can be used to make payments at stores, restaurants, and other businesses.

Contactless Access Control:

NFC-enabled cards and tags can be used to open doors, start cars, and access other secure areas.

Data Transfer:

NFC can be used to transfer data between devices, such as contacts, photos, and music.


NFC can be used to deliver targeted advertising to users when they bring their devices near NFC-enabled posters or displays.

Here are some additional details about NFC:

  1. NFC operates in the 13.56 MHz frequency band.
  2. NFC has a maximum range of about 4 centimeters.
  3. NFC uses less power than other wireless technologies, such as Bluetooth and Wi-Fi.
  4. NFC is a secure technology that uses encryption to protect data.
  5. NFC is a contactless technology, which means that users do not need to physically touch their devices together in order to communicate.

NFC is a rapidly growing technology that is being adopted by a wide range of industries. Here is a small list of tech giants that actively use NFC in different products.

  • Apple
  • Google
  • Samsung
  • Visa
  • Mastercard
  • American Express

This list is not just limited to tech companies only. Many non-tech companies like: Starbucks, and McDonald’s also use NFC.

As NFC technology continues to develop, we can expect to see even more widespread adoption of this technology. NFC has the potential to revolutionize the way we interact with the world around us, and it is poised to play a major role in the future of mobile payments, contactless access control, and data transfer.
