We are developing a clover application that would create a custom tender namely "Loyal Patron". Here this tender would be displayed on clover Payment application screen. Now when merchant will click on this tender then our app screen(with some input fields) will be opened. So here we required to identify our loyal patron customer by card number or mobile number. On this my screen we say to swipe the loyalty card.
Now I want to get some information like mobile number from the card when loyalty card is swiped so that we can put the mobile number into the field without manual interaction to proceed further.
So please suggest me how we could implement this functionality like getting info from loyalty card on my app screen on swiping card.
Please consider attached screen to get better understanding.
