Cordova Integration Guide

Importing DyScan

After getting your access token, navigate to your Cordova project directory and install DyScan with the following terminal command:

cordova plugin add https://[e-mail]/Dyneti/dyscan-cordova.git

When asked for a password for user "dyscan", paste the access token that we provided.

You may encounter this error: Failed to fetch plugin https://[e-mail]/Dyneti/dyscan-cordova.git via registry. Probably this is either a connection problem, or plugin spec is incorrect. Check your connection and plugin name/version/URL. CordovaError: Error: command failed

If you do, first clone the repo manually into a directory:

git clone https://[e-mail]/Dyneti/dyscan-cordova.git

and then add the plugin to your Cordova project:

cordova plugin add ./dyscan-cordova

Interfacing DyScan

Initializing DyScan

In your main JS file, e.g., index.js, add the following line to configure DyScan.

document.addEventListener('deviceready', onDeviceReady, false);

function onDeviceReady() {
    DyScan.init({
        apiKey:'YOUR_API_KEY'
    });
}

Camera features support

The DyScan.isDeviceSupported function should be called to verify if the device is supported before calling DyScan functions to avoid a bad user experience.

DyScan.isDeviceSupported(function(supported) {
    if (supported) {
        // open DyScan card scan
        DyScan.scanCard({showDynetiLogo: true}, onScanSuccess, onScanFailure);
    } else {
        // alternate flow if device is not supported
    }
})

Card Scan

The DyScan.scanCard function uses the DyScanViewController on iOS and the DyScanActivity on Android. It will open a separate screen where the user will scan their card. The card data will be available via success callback, error info via failure callback.

function scanButtonClick() {
    DyScan.scanCard({showDynetiLogo: true}, onScanSuccess, onScanFailure);
}

function onScanSuccess(result) {
    // the scanned card
    // Access the fields cardNumber, expiryMonth, or expiryYear
}

function onScanFailure(error) {
    // the user cancelled
}

Color Representation

Colors are inputted as hex-encoded strings representing the RGB values with a '#' at the front, the so-called 'HTML Color Codes.' For example, #ff0000 is red. The representation must be exactly 7 characters long; otherwise we will ignore it when trying to convert the strings to the native representations.
