Hardware Access / QR And Barcode Scanner - Android SDK

Intro

How to use the qr and barcode scanner on a supported pax device.

Dedicated QR And Barcode Scanner

This functionality is currently only available on the pax A77 terminal. The following code snippet demonstrates how you can use the dedicated qr and barcode scanner on a supported pax device and getting the scanned result.

    HardwareService paxService = new PaxService();
    BarcodeScannerDelegate barcodeScannerDelegate = new BarcodeScannerDelegate() {
            @Override
            public void onSuccess(String barcodeScannerResult) {
                //scan completed
            }

            @Override
            public void onError(Error error) {
                // scan failed
            }
        };
        
    paxService.scanBarcode(1000, barcodeScannerDelegate, getBaseContext());

Camera QR And Barcode Scanner

The following code snippet demonstrates how you can use the camera qr and barcode scanner on a supported pax device (= Types A920, A77 & IM30) and getting the scanned result.

    //SurfaceView from Layout
    SurfaceView surfaceView;

    HardwareService paxService = new PaxService();
    BarcodeScannerDelegate barcodeScannerDelegate = new BarcodeScannerDelegate() {
            @Override
            public void onSuccess(String barcodeScannerResult) {
                //scan completed
            }

            @Override
            public void onError(Error error) {
                // scan failed
            }
        };
        
    paxService.scanBarcode(surfaceView, barcodeScannerDelegate, activity);

    //Make sure to close camera by calling stopScanBarcode
    @Override
    protected void onDestroy() {
        if(paxService != null){
            paxService.stopScanBarcode();
        }
        super.onDestroy();
    }
