card.io plug-in for Cordova

This plug-in exposes card.io credit card scanning.

Note: If you would like to actually process a credit card charge, you might be interested in the PayPal Cordova Plug-in.

If you discover a problem here, please submit an Issue or Pull Request. (Unless, of course, the problem is actually in the underlying card.io SDK for either iOS or Android. We're always interested in discovering and fixing bugs in our SDKs!)

Supported configurations

The card.io Cordova plugin provides different configurations that could be set according to your requirements. Here are the list of supported configurations.

| Configuration | Type | Description | | :------ | :------ | :------ | | requireExpiry | Boolean | Expiry information will not be required. | | requireCVV | Boolean | The user will be prompted for the card CVV | | requirePostalCode | Boolean | The user will be prompted for the card billing postal code. | | suppressManual | Boolean | Removes the keyboard button from the scan screen. | | restrictPostalCodeToNumericOnly | Boolean | The postal code will only collect numeric input. Set this if you know the expected country's postal code has only numeric postal codes. | | keepApplicationTheme | Boolean | The theme for the card.io Activity's will be set to the theme of the application. | | requireCardholderName | Boolean | The user will be prompted for the cardholder name | | scanInstructions | String | Used to display instructions to the user while they are scanning their card. | | noCamera | Boolean | If set, the card will not be scanned with the camera. | | scanExpiry | Boolean | If scanExpiry is true, an attempt to extract the expiry from the card image will be made. | | languageOrLocale | String | The preferred language for all strings appearing in the user interface. If not set, or if set to null, defaults to the device's current language setting. | | guideColor | String | Changes the color of the guide overlay on the camera. The color is provided in hexadecimal format (e.g. "#FFFFFF") | | suppressConfirmation | Boolean | The user will not be prompted to confirm their card number after processing. | | hideCardIOLogo | Boolean | The card.io logo will not be shown overlaid on the camera. | | useCardIOLogo | Boolean | The card.io logo will be shown instead of the PayPal logo. | | suppressScan | Boolean | Once a card image has been captured but before it has been processed, this value will determine whether to continue processing as usual. |

Integration instructions

The card.io Cordova Plugin adds support for the CardIO iOS and android platform. It uses the native CardIO library. Cordova plugin management will set up all the required capabilities/frameworks for the project. The only bit left for you to do is to add necessary files, as described below.

1. Follow the official Cordova documentation to install command line tools.
2. Create project, add plugin and platforms:

   $ cordova create ScanCard com.mycompany.scancard "ScanCard"
   $ cd ScanCard
   $ cordova platform add ios
   $ cordova platform add android
   $ cordova plugin add https://github.com/card-io/card.io-Cordova-Plugin

1. Follow Your app integration section below.
2. Run cordova run ios or cordova run android to build and the project.

Sample HTML + JS

1. In ScanCard/www/index.html add the following to lines after <p class="event received">Device is Ready</p>:

      <button id="scanBtn"> Scan Now!</button>

1. Replace ScanCard/www/js/index.js with the following code:
