Revenue
Controls for transient parkers usually include ticket issuing machines
at the entrances, and parking fee computers at the exits. The calculated
parking fee is displayed to the cashier and to the customer with the
details of the transaction being recorded and used for revenue and
statistical reports. A machine readable system encodes the time and
date on the ticket when it's issued and the ticket is automatically
read at the exit.
Pay on Foot stations allow for the parking fee to be calculated
at a centrally located machine which then returns the re-encoded
parking ticket to the customer to be used as an exit pass at an
unattended exit gate. Parking fees can be satisfied by bills, coins,
credit cards, vouchers (payment by another party), or debit cards.
Debit cards are plastic cards which have been encoded with a monetary
value which is reduced when the parking fee is subtracted.
