Capacitor Unimag Swiper

The purpose of this plugin is to allow for swiping credit cards using the IDTech UniMag II, UniMag Pro, or Shuttle mobile readers in hybrid applications.

Supported Platforms

• iOS

Installation

npm install capacitor-unimag-swiper

npx cap sync ios

Usage

The IDTech reader can be used by calling the activate method on your plugin object. Here, "activated" means that the plugin will be able to listen to IDTech SDK events. The IDTech SDK (hereby referred to simply as SDK) sends a wide variety of events related to reader tasks such as connection and swipe. In response to some of these events, the plugin will fire its own events that you can capture in your application.

A reader may be either attached or detached. It is attached when it is plugged into the mobile device running your application. While the reader is activated, once a reader is attached, (or if it is already attached upon application startup) the SDK will begin a connection task with the reader. When this task begins, a "connecting" event will be fired from the plugin. After the task has finished successfully, a "connected" event will fire. If a connection could not be established, a "timeout" event will be fired instead. Once you have captured the "connected" event you can begin initiating the swipe process.

To initiate the swipe process, call the swipe method on your plugin object. After this method has been called you can physically swipe the card. The data will be parsed and returned if valid. This will result in a "swipe_success" event containing the data (it will be stringified, you will need to parse it). If the card data was invalid, or the swipe was otherwise unsuccessful (e.g., if it was crooked) you a "swipe_error" event will be fired instead.

You can deactivate the reader by calling the deactivate method. Once the reader has been deactivated, it will not listen to attachment/detachment and will never attempt a connection. The reader need not be attached for it to be activated successfully - if it is activated, it will automatically detect attachment/detachment and handle connection as such.

NOTE: To use this plugin you'll need to disable bitcode. You can do this by clicking on your project in Xcode and going to Build Settings. Search for 'bitcode', and you'l see an 'Enable Bitcode' setting. Change this to 'No'.

Events

See Sample section for how exactly to capture the events listed below.

Sample

const { CapacitorUnimagSwiper } = Plugins;

connected = false;
activated = false;

async activate() {
    const result = await CapacitorUnimagSwiper.activateReader();
    result === "active" ? this.activated = true : this.activated = false;
}

ngOnInit() {


Plugins.CapacitorUnimagSwiper.addListener('uniMagPoweringNotification', (info: any) => {
    console.log('Swiper connecting');
});

Plugins.CapacitorUnimagSwiper.addListener('uniMagDidConnectNotification', (info: any) => {
    console.log('Swiper connected');
    this.connected = true;
});

Plugins.CapacitorUnimagSwiper.addListener('uniMagDidDisconnectNotification', (info: any) => {
    console.log('Swiper disconnected');
    this.connected = false;
});

Plugins.CapacitorUnimagSwiper.addListener('uniMagDidReceiveDataNotification', (info: any) => {
    // data from successful card swipe
    let responseData = JSON.parse(info.detail);
    console.log('Swipe success', cardData);
});
        
    this.activate();

}
