What is NFC and how does it work? Everything you need to know
NFC has evolved from a quality-of-life feature to something many of us rely on every day.
You’ve probably heard of it before and may even own a smartphone that features that technology, but what is NFC on a phone anyhow? Most smartphones these days are equipped with Near Field Communication technology, better known as NFC. In a nutshell, it is a proximity-based wireless communication standard. Unlike Wi-Fi or Bluetooth, however, NFC interaction is limited to an extremely short range.
Mobile payments
As we gradually transition to a cashless world, mobile payments have become a popular transaction method. With bank cooperation and the biometric technology built into most modern smartphones, making a mobile payment is secure and convenient. Placing your smartphone within 4 inches of the contactless reader in a store will prompt your digital wallet or passbook to pop up and ask you to confirm payment. With Apple Pay, this means placing your finger on the Home button, which houses the Touch ID function, or double-pressing the Power button to scan your face with Face ID. It also works with Google Pay and Samsung Pay.
