Now the response received in the code here will be in the result variable of read() method.And likewise you can write your own commands for communicating. Something went wrong as count was : ' + byteCount Buffer received was : result.toString() Result.append(String.format(' %02X ', bb)) UsbDeviceConnection connection = mUsbManager.openDevice(device) MUsbManager.requestPermission(device, mPermissionIntent) Īnd now you will need endpoints, simply send an APDU (smartcard command) over the bulk-out endpoint and expect to receive a response APDU over the bulk-in endpoint.Ĭode to get endpoints :: UsbEndpoint epOut = null, epIn = null UsbDevice device = deviceList.get('//the device you want to work with') In basic terms, NFC allows nearby devices to communicate through radio waves so they dont have to make physical contact with the payment terminal to complete the purchase. HashMap deviceList = mUsbManager.getDeviceList() Tap to pay uses a technology called near-field communication (NFC) to share payment information.

PendingIntent mPermissionIntent = PendingIntent.getBroadcast(this, 0, new Intent(ACTION_USB_PERMISSION), 0) UsbManager mUsbManager = (UsbManager) getSystemService(Context.USB_SERVICE) įinal String ACTION_USB_PERMISSION = '_PERMISSION' : //Allows you to enumerate and communicate with connected USB devices. In java the communication takes place using package javax.smarcard which is not available for Android so take a look here for getting an idea as to how you can communicate or send/receive APDU (smartcard command).
