I use Ricks tutorial for being able to suspend transactions so more than one person can use each till when a fob is swiped. If someone is using the till another person can come along, suspend the transaction by using their fob and refob to bring up the POS screen with their username as the entity.
My goal is to make our system work like ICR Touch and instead of logging out it stays on the POS screen. When a staff member swipes their fob it selects their staff name entity and if another fob is presented it holds that order, closes the ticket and allows another staff to fob on. Is there any way of preventing users using the POS screen without first swiping their fobs to assign their staff entity to the ticket? The logging out to pin screen creates a bit of a delay in a nightclub environment.
