About The Project

This package is a bridge to the uareu library developed for Android in Java.

Allows a mobile application developed in React Native to use the external fingerprint reader digitalPersonal 4500.

This project works only on Android, in some future it could be implemented for IOS

`$ npm install react-native-fingerprint-uareu-v1 --save`

If you have problems with the installation try the following command:

const App = () => {
  const [fingerPrintPick, setFingerPrintPick] = useState('');

  const scanFinger = async () => {
    var { encoded, convertBase64 } = await FingerPrintUareu.startScan();
	//var convertBase64 is encoded with WSQEncoder
	//var encoded is encoded in base64
    setFingerPrintPick(encoded);
  }

  return (
    <SafeAreaView>
		/* Change this implementation at your convenience */
      <Text>Finger: {fingerPrintPick}</Text>
      <Button
        onPress={() => scanFinger()}
        title="Escanear"
      />

    </SafeAreaView>
  );
};
