Techopedia Explains Near Field Communication Tag

Many of today’s smartphones have built-in NFC capabilities, and smartphone users can purchase and acquire tags online. The amount of information stored on a NFC tag depends on the tag type, as tag memory capacity varies by tag. For example, a tag can store a phone number or URL.

A modern example of a commonly used NFC tag function is mobile payment processing, where users swipe or flick a mobile phone on a NFC reader. Google’s version of this system is Google Wallet.
