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:
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.
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:
- NFC operates in the 13.56 MHz frequency band.
- NFC has a maximum range of about 4 centimeters.
- NFC uses less power than other wireless technologies, such as Bluetooth and Wi-Fi.
- NFC is a secure technology that uses encryption to protect data.
- 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.
- 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.
How To Turn On NFC On iPhone:-
The process of turning on NFC on iPhones varies according to the iOS version. Here, we have discussed the steps for iPhone 7, 8, and X.
- To open the Control Center on your iPhone 8 or iPhone 7, all you need to do is to swipe up from the bottom of the screen.
- And if you are an iPhone X user, you can open the Control Center by swiping down from the top right-hand corner of the screen.
- Tap the NFC Tag Reader icon to turn on NFC.
You can now use NFC to interact with other devices or tags.

- If you don’t see the NFC Tag Reader icon in Control Center on iPhone 7, 8, or X, you’ll need to add it to your Control Center through Settings.
- Open the Settings app.
- Tap Control Center.
- iPhone control center settings
Scroll down to the More Controls section and tap the Plus (+) icon next to NFC Tag Reader.
Add NFC tag reader to the control center
- Repeat steps 1-3 above.
Once NFC is turned on, you can use it to make payments with Apple Pay, share contact information, connect to other devices, and read NFC tags.
Things to keep in mind about NFC on iPhone
Here are some additional things to keep in mind about NFC on iPhone:
NFC only works over short distances. The distance is just 4 cm. That’s why make sure that your iPhone is close or in direct contact with the other device or NFC tag you’re trying to interact with.
Not all iPhones have NFC capabilities. To check if your iPhone has NFC, go to ‘Settings’ > ‘General’> ‘About’. If you see ‘NFC’ under ‘Wireless & Networking’ , then your iPhone has NFC capabilities.
If you’re having trouble using NFC on your iPhone, try restarting your iPhone.
Uses of NFC on iPhone
NFC is a versatile technology that can be used for a variety of purposes. By turning on NFC on your iPhone, you can start using it to make payments, share contact information, connect to other devices, and read NFC tags.
Make Payments With Apple Pay:
NFC is the primary technology used for Apple Pay. To make a payment with Apple Pay, simply hold your iPhone near a contactless payment reader.
Share Contact Information:
You can use NFC to share your contact information with another person. To do this, open the ‘Contacts app’ and tap on the contact you want to share. Then, tap on the ‘Share Contact ‘button and select ‘NFC’.
Connect To Other Devices:
NFC can be used to make a connection between your iPhone and other devices that have NFC. It’s very easy to connect your iPhone to other NFC devices. All you need to do is to hold your iPhone in close contact with the NFC-enabled device.
You can use NFC to connect your iPhone to other devices, such as speakers, headphones, and printers. To do this, hold your iPhone near the other device until it is detected.
Read Nfc Tags:
NFC tags are small, wireless devices that can store data. You can use NFC tags to store things like website links, contact information, and even coupons. To read an NFC tag, simply hold your iPhone near the tag until it is detected.
