What is NFC?

NFC stands for Near-field communication. It is a communication protocol that enables two electronic devices to communicate with each other over a distance of 4 cm or less. NFC is a type of wireless short range high frequency communication technology that allows devices such as laptops, smartphones, tablets and more to share data when in close proximity.

NFC is generally used as technology in contactless cards. More often than not when you have an NFC-enabled phone, it is used for making easy payments without having to pull out your card and input a security pin. NFC can also be used to quickly connect to a range of devices and share data.

There are plenty of usecases for NFC apart from its mainstream use of contactless payment. You can program NFC to perform a range of tasks. For instance, you can instantly connect to a Wi-Fi network without having to fiddle with your mobile settings. Once you are in proximity, it will instantly connect.

There is an obvious similarity as both technologies use a wireless connection to transfer data. Unlike Bluetooth, you don't need to manually pair two devices in the case of NFC. The connection is established within 0.1 Seconds. However, NFC operates at a far slower speed and has a shorter range as well. Due to this, it also consumes less energy.
