Near Field Communication (NFC)
Candlefocus EditorNFC devices, such as smartphones, tablets, wearables, and laptops, contain special NFC chips, allowing them to sense, interpret, and exchange data from one another over short distances up to 4 inches (10 cm). This range works by creating an electric field around both NFC-enabled devices, which then exchange information behind the scenes. NFC is distinct from other wireless technologies such as Bluetooth, as all devices must be in close physical proximity to each other in order to enable the transfer.
NFC technology can operate in one of three primary modes. In the reader/writer mode, an NFC-enabled tag exchange data with the reader. For example, a smartphone can read NFC tags on a billboard to access an advertisement, coupon, or other related information. In the peer-to-peer mode, two NFC-enabled devices transfer data. For example, two smartphones can share photos by simply bringing them in close proximity to one another. In card emulation mode, NFC-enabled devices emulate an NFC card and interact with an NFC reader. In this way, it can provide a more secure connection for making payments or carrying out identification and authentication activities.
NFC technology is slowly gaining traction across multiple industries due to its convenience and security. Businesses and organizations can offer a secure and convenient way of accessing services and products, in addition to automating and streamlining payment, authentication, and other processes. NFC also helps make our lives easier, allowing us to share data between devices and make contactless payments with our smartphones.
