Qt NFC▲
The NFC API provides connectivity between NFC enabled devices.
Currently, the API is supported on Android and iOS.
NFC is a short-range (less than 20 centimeters) wireless technology with a maximum transfer rate of 424 Kbps. NFC is ideal for transferring small packets of data when two devices are placed together.
The NFC module provides APIs for interacting with NFC Forum Tags and NFC Forum Devices. It can detect targets and losses, register NDEF message handlers, read and write NDEF messages on NFC Forum Tags, and send tag-specific commands.
Using the Module▲
Using a Qt module requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including http:// and https://.
Building with CMake▲
Use the find_package() command to locate the needed module component in the Qt6 package:
find_package(Qt6 REQUIRED COMPONENTS Nfc)
target_link_libraries(mytarget PRIVATE Qt6::Nfc)For more details, see the Build with CMake overview.
Building with qmake▲
To configure the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:
