NFC Explained

What is NFC?

 

NFC (Near Field Communication) is a technology that enables devices (e.g. smartphones) to interact with the physical world by touching, tapping or waving near a tag. No swiping, inserting or pin entry needed and there’s no need to download an app or visit a website.  

 

What is an NFC tag?

 

An NFC tag can be placed on or in various items, e.g. sticker, posters or wristbands. It contains a microchip which stores a small amount of information for transfer to an NFC device, such as a smartphone.  

 

What can I use NFC for?

 

Touching your smartphone to an NFC tag can initiate different types of actions including a Facebook like,  Twitter follow, voucher download, digital tickets, opening a web page or video, entering a competition, prompting a call or SMS with a phone number.  

 

What information can an NFC tag store?

 

NFC tags can store different types of data for example a URL (web address) or phone number. The amount of data you can store depends on the type of NFC tag – different tags have different memory capacities but this is usually between 40 and 130 characters.

 

Do all phones have NFC?

 

Older phones say older than 9 years old don’t have NFC built in so there’s still a way to go before everyone has an NFC device in their pocket. However, many new Android™ and Windows™ phones have NFC including new Blackberries, the Samsung Galaxy Nexus, new HTCs and Nokias. Apple™ does have NFC inside their iPhone 6 and iPhone 6s models but it can only be used for payments and not for reading or writing to NFC tags. iPhone 7 & 8  & X and 7+ & 8+  have NFC Tag reading capability but you have to have to use an appliaction. IPhone Xs, Xs+ and XR not only have NFC reading capability and you can launch a URL with requirement for an application.  PLease note that you can not currently write to NFC tags with any iPhone model.  

 

Do NFC tags need batteries?

 

NFC tags don’t need batteries – they get their charge from being near an NFC-enabled device, for example a smartphone.
