What is NFC?

NFC stands for Near Field Communication and it is a technology that has been around since 2004. It allows two devices to talk to each other when they are in close proximity of one another, usually within 4 inches. The most popular use of NFC technology today are Apple Pay and Google Pay which lets you tap your phone on the credit card terminal at checkout instead of swiping your card.

NFC is an upgrade of the existing proximity card standard that combines a smartcard and reader into one device. With NFC, users can seamlessly share content between digital devices or even use their cellphone as an electronic traveling ticket on contactless infrastructure already in use for public transportation.

The NFC connection is established in under 1/10th of a second. This offers an advantage over Bluetooth, which can take up to ten seconds for manual configurations just to identify the devices connecting. The NFC is better than Bluetooth because it sets up faster. Instead of performing manual configurations to identify the devices, you can establish an instant connection between two NFC-enabled phones or other mobile electronic device in under a second.

NFC is a more secure form of technology than Bluetooth because it provides shorter range. This means that NFC has the ability to work in crowded areas where you can’t find your phone, for example at an event or concert when there are plenty people around and cell phones cannot be tracked by correlating them with their physical device they transmit from.

With NFC, you can still use your phone even when it’s not powered by a battery. For example if you have a contactless smart credit card or any other device that is enabled with the technology and turned off in some way, an operator could tap their own unlocked mobile phones to activate yours so long as both devices are close enough together.
