Passing employee account number from employee's phone to Arduino

This will be an activity in the app that will pass the account number via nfc once the employee signs in on the app. The Arduino will need a way of transitioning from receiving the account number to sending it. For now I will probably just make it sequential. When the Arduino starts it will automatically be in receiving mode. Once it receives the account number it will transition to send mode and won't be able to go back unless it is reset. If we have time we can add a button for this later.
