CAYAN DEBIT CASH BACK

Yes Debit cash back works with cayan, if the client wants to use the cash back function the debit button has to be added to the tender screen and the amount of cash back has to be entered in the field before sending the transaction to the genius device. we tried adding the buttons to the cayan unit and allowing the customer to select the amount but it will approve a 0$ amount and automatically void on the cayan side.
