+##Using The Card Scanner
+Define an instance level variable to hold the request code
+```Java
+private final static Integer PROMISE_PAY_REQUEST_CODE = 10;
+```
+
+Use an intent to start the card scanner
+```Java
+Intent myIntent = new Intent(this, PromisePayScanActivity.class);
+startActivityForResult(myIntent, PROMISE_PAY_REQUEST_CODE);
+```
+
+Override onActivityResult to catch the result
+```Java

+protected void onActivityResult(int requestCode, int resultCode, Intent data) {
+    super.onActivityResult(requestCode, resultCode, data);
+
+    if (requestCode == PROMISE_PAY_REQUEST_CODE) {
