This type of communication can occur over a distance of about four centimeters.

It offers a low-speed connection, which is sometimes used as a bootstrap for more capable wireless.

NFC technology can be used for various applications. It has three modes of operation: reader/writer mode.

In peer-to-peer mode, two devices exchange data in order to carry out a transaction.

[{"selector":"#anim-96b9e1ca-86bc-4d53-84b7-0927a9fe6d0e","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-6c6f373f-af66-4a8d-93bd-ebf4ab70a78a","keyframes":{"transform":["translate3d(0px, 185.38405%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-ce058879-6c5f-46e1-b902-503cb78dcac9 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

In this mode, any device can be the initiator and the other can act as the receiver.

The active device can read the data stored on the NFC tag.

For example, a smartphone could serve as a keycard for an office building and open doors automatically.
