7\title Qt NFC
8\brief Enables connectivity between NFC enabled devices.
9\ingroup technology-apis
10
11The NFC API provides connectivity between NFC enabled devices.
12
13Currently, the API is supported on \l{Qt for Android}{Android}, \l{Qt for
14iOS}{iOS} and \l{Qt for Linux}{Linux} using
15\l {https://github.com/linux-nfc/neard}{Neard} v0.14 or later.
16This module also provides limited access to readers supporting
17\l{PC/SC in Qt NFC}{PC/SC} specification on Linux, macOS, and Windows.
18
19NFC is a short-range (less than 20 centimeters) wireless technology
20with a maximum transfer rate of 424 Kbps. NFC is ideal for transferring
21small packets of data when two devices are placed together.
22
23The NFC module provides APIs for interacting with NFC Forum Tags and NFC Forum
24Devices. It can detect targets and losses, register NDEF message handlers, read
25and write NDEF messages on NFC Forum Tags, and send tag-specific commands.
