My 1st time experience...was a little different than in the Wiki.
Tried to swipe 4 times with one transaction. The cashier said the software will not allow a 4th swipe. Had to cancel and start all over.
Told cashier the amount of MO and wanted to pay with three (3) cards at $xxx each. She said go ahead with 1st swipe. Did not have the option to select "debit". Entered my PIN. The software asked if I wanted cash bacK? I selected "no". All three swipes went OK and I paid the $0.88 for the MO in cash.
Did the cashier screw something up when she advised me the software would not allow a 4th swipe?
