If the customer inserts their debit card and takes it out before the transaction is over (before I hit total), then they have to insert their debit card again right? Because that happened a couple of times today, and the computer just said “paying” for a really long time even though the card was taken out already and it usually says authorizing after the debit card is inserted, so I asked them to insert their card again after i hit total (and it worked). I just want to make sure that they aren’t doubled charged... Or should I have waited longer for the computer to process when the system said “paying”?
