A fully featured implementation of card.io for iOS and Android.

Installation iOS

3. Within node_modules, find react-native-card-io/ios and add RCTCardIO.xcodeproj to your project.
4. Add libRCTCardIO.a to Build Phases -> Link Binary With Libraries.
5. Add the -lc++ flag to Build Settings -> Other Linker Flags.

Installation Android

TODO: Currently building a react-native app for iOS and Android, so this will be done soon :)

Usage

import {CardIOView, CardIOUtilities} from 'react-native-card-io'

...

componentDidMount() {
  // The preload method prepares card.io to launch faster. Calling preload is optional but suggested.
  // On an iPhone 5S, for example, preloading makes card.io launch ~400ms faster.
  // The best time to call preload is when displaying a view from which card.io might be launched;
  // e.g., inside your view controller's componentDidMount method.
  // preload works in the background; the call to preload returns immediately.
  CardIOUtilities.preload();
},

render() {
  if (CardIOUtilities.canReadCardWithCamera) {
    return (
      <View>
        <CardIOView
          languageOrLocale="en_AU"
          guideColor="#FF0000"
          useCardIOLogo={true}
          hideCardIOLogo={false}
          allowFreelyRotatingCardGuide={true}
          scanInstructions={'Hold card here. It will scan automatically.'}
          scanExpiry={true}
          scannedImageDuration={2}
          detectionMode={CardIOView.cardImageAndNumber}
          didScanCard={result => console.log(result)} />      
      </View>
    );
  }
  return (
    <View style={styles.noCamera}>
      <Text>card.io requires a camera</Text>
    </View>
  );
}

CardIOView

props

See card_io_view.js for all React.PropTypes. All props are optional and the view can be used with simply:

<CardIOView style={{flex: 1}} />

didScanCard

The didScanCard function returns the following object:

{
  cardNumber: string,
  redactedCardNumber: string,
  expiryMonth: number, // January == 1
  expiryYear: number,
  cvv: string,
  postalCode: string,
  scanned: boolean,
  cardImage: string, // base64
  cardType: string,
  logoForCardType: string, // base64
}

To display the images returned by didScanCard use the following:

<Image source={{uri: 'data:image/png;base64,'+ cardImage, isStatic: true}} />

TODO

• Android implementation
• implement CardIOPaymentViewController
• add rotation notifications

Secure

card.io does not store or transmit credit card numbers. Recommend using the Privacy Snapshot react-native component if using with iOS to blur the screen when the app is backgrounded.
