React Native ⚛

Our CardScanView react component makes it easy to add insurance card scanning to any web application in 5 minutes or less.

Installation

$ npm i @cardscan.ai/insurance-cardscan-react-native
$ yarn add @cardscan.ai/insurance-cardscan-react-native

Usage

Import the library widget into your project files:

import { CardScanView } from "@cardscan.ai/insurance-cardscan-react-native";

Basic Example

import React from 'react';
import { SafeAreaView, StyleSheet } from 'react-native';
import { CardScanView } from '@cardscan.ai/insurance-cardscan-react-native';

function onSuccess(card: any) {
  console.log('new card: ', card);
}

function onError(error) {
  console.error('Error occurred: ', error);
}

// See Authentication on where to get this sessionToken.
const sessionToken = 'JWT_TOKEN';

export default function App() {
  return (
    <SafeAreaView style={styles.container}>
      <CardScanView 
        live={false} 
        sessionToken={sessionToken} 
        onSuccess={onSuccess} 
        onError={onError}
      />

    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});

onSuccess Callback

The onSuccess prop allows you to execute a custom function when the card scanning process is completed successfully. This function receives the scanned card data as an argument.

Usage

To use the onSuccess prop, pass a function that receives the scanned card data:

const handleCardScanSuccess = (cardData) => {
  console.log('Card scanned successfully:', cardData);
};

<CardScanView
  sessionToken={token}
  onSuccess={handleCardScanSuccess}
/>

In this example, the handleCardScanSuccess function logs the scanned card data to the console when the scanning process is completed successfully.

onError Callback

The onError prop allows you to execute a custom function when there's a failure during the card scanning process. This function receives an error object as an argument.

Usage

To use the onError prop, pass a function that receives the error object:

const handleCardScanError = (error) => {
  console.error('Scanning failed:', error);
};

<CardScanView
  sessionToken={token}
  onSuccess={cardScanSuccess}
  onError={handleCardScanError}
/>

In this example, the handleCardScanError function logs the error object to the console when a scanning failure occurs.

By using the onSuccess and onError props, you can handle successful and failed scanning events, allowing you to implement custom actions or display appropriate messages to the user.

onCancel Callback

The onCancel prop enables you to execute a custom function when the user cancels the card scanning process. This can be useful for tracking user behavior, navigating to a different part of the application, or displaying an appropriate message.

Usage

To use the onCancel prop, pass a function that will be executed when the user cancels the scanning process:

import React, { useState } from 'react';
import { View } from 'react-native';
import { CardScanView } from '@cardscan.ai/insurance-cardscan-react-native';



const App = () => {
  const [showCardScanView, setShowCardScanView] = useState(true);

  return (
    <View>
      {showCardScanView && (
        <CardScanView
          sessionToken={token}
          onSuccess={cardScanSuccess}
          onError={cardScanError}
          onCancel={() => setShowCardScanView(false)}
        />
      )}
    </View>
  );
};

export default App;

In this example, we initialize the showCardScanView state variable to true. Then, we conditionally render the CardScanView component based on the value of showCardScanView. We then use the onCancel prop to set the showCardScanView state variable to false when the user cancels the scanning process.

onRetry Callback

The onRetry prop allows you to execute a custom function when a retry is triggered due to a scanning failure.

Usage

To use the onRetry prop, pass a function that receives the retry event as an argument:

const handleRetry = (event) => {
  console.log('Retry triggered:', event);
};

<CardScanView
  sessionToken={token}
  onSuccess={cardScanSuccess}
  onRetry={handleRetry}
/>

In this example, the handleRetry function logs the retry event to the console when a retry is triggered.
