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.

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.
usePaypalActionbarIcon	Boolean	Use the PayPal icon in the ActionBar

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.

iOS Quirks

Since iOS 10 it's mandatory to add a NSCameraUsageDescription and NSPhotoLibraryUsageDescription entry in the info.plist.

NSCameraUsageDescription describes the reason that the app accesses the user's camera. NSPhotoLibraryUsageDescription describes the reason that the app accesses the user's photo library (which this plugin does not actually do but it invokes APIs that still require the entries.

When the system prompts the user to allow access, this string is displayed as part of the dialog box. To add this entry you can pass the variable CARD_IO_CAMERA_USAGE_DESCRIPTION & CARD_IO_PHOTO_LIBRARY_USAGE_DESCRIPTION on plugin install.

Example: cordova plugin add https://github.com/card-io/card.io-Cordova-Plugin --variable CARD_IO_CAMERA_USAGE_DESCRIPTION="your usage message"

If you don't pass the variable, the plugin will add a default string as value.

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:
