Scanning GS1 Databar Barcode in IOS with react-native

Question

I want to scan GS1 Databar Barcode which is also known as RSS Expanded barcode in IOS with react-native, I am using react-native-qrcode-scanner https://github.com/moaazsidat/react-native-qrcode-scanner to scan barcodes.

<QRCodeScanner
                onRead={this.onSuccess}
                showMarker={true}
                reactivate={false}
                flashMode={RNCamera.Constants.FlashMode.auto}
                topContent={
                    <View>
                        <Text>
                            Scan Coupon Barcode
                    </Text>
                        <Text>Please fit the barcode within the {'\n'} box on the screen.</Text>
                    </View>
                }
                cameraStyle={styles.cameraContainer}
                topViewStyle={styles.topcontainer}
                bottomViewStyle={styles.zeroContainer}
                markerStyle={styles.markerStyle}
                containerStyle={styles.container}
            />

It is working fine in android, but failing to pick barcodes in IOS. In IOS QR Code, EAN-8 barcodes are being scanned successfully, but GS1 Databar is not being scanned.

Answer 1

No efficient open source solutions found for scanning GS1 Databar Expanded barcodes on iOS using React-Native.

Tried Zxingify-ObjC as a native module but the scanning is poor on newer iPhones (11 Pro, 12).

Tried react-native-barcode plugin. Doesn't support GS1 Databar plugin using the camera scanner, but does support scanning GS1 Databar from static images.

Finally went for a paid SDK: Cognex.

Hope this helps someone who runs into the same problem.

Answer 2

string.replace(/\D/g, "") apply this method on resulted string.
