8\brief Enables connectivity between NFC enabled devices.
9\ingroup technology-apis
11The NFC API provides connectivity between NFC enabled devices.
13Currently, the API is supported on \l{Qt for Android}{Android} and \l{Qt for
14iOS}{iOS}. This module also provides limited access to readers supporting
15\l{PC/SC in Qt NFC}{PC/SC} specification on Linux, macOS, and Windows.
17NFC is a short-range (less than 20 centimeters) wireless technology
18with a maximum transfer rate of 424 Kbps. NFC is ideal for transferring
19small packets of data when two devices are placed together.
21The NFC module provides APIs for interacting with NFC Forum Tags and NFC Forum
22Devices. It can detect targets and losses, register NDEF message handlers, read
23and write NDEF messages on NFC Forum Tags, and send tag-specific commands.
