Qt NFC Overview
With the Qt NFC API typical use cases are:
- Detecting NFC tags.
- Reading and writing NDEF messages.
- Registering NDEF message handlers.
- Sharing files and messages.
The following sections describe how to use Qt NFC C++ classes and QML types for the above use cases.
Note: On Android, the detection of new NFC tags only works in foreground applications. Android services do not support this because of API limitations on the Android side. The only way to use a Tag in a service is to provide an AIDL interface accepting the Tag and forward it to Qt as shown in the following example.
