Use the following guidelines to process debit cards at POS. These guidelines include the actions of the clerk and the customer. The customer's actions occur on a device called a "combo device" which has a keypad and a mag-stripe reader for swiping the card. Some combo devices also have a signature pad for electronic signature capture.
Before you begin, note the following restrictions:
You can't manually enter the card number for online debit (ATM) transactions.
You can’t run a debit card with other forms of credit authorization in one transaction (unless the other tender is a Gift Card).
Offline POS does not support debit cards as a form of tender, because a debit transaction must be approved by the processor or it cannot occur. In contrast, Offline POS does allow you to accept credit cards.
As the clerk rings up the items, the customer can begin interacting with the combo device (swiping card, entering pin number, etc., as requested by the combo device)
When the clerk totals the transaction, the system queries the combo device for tender information.
If tender information is present (the customer has already swiped his/her card, entered pin number, etc.), the transaction continues to process.
If no tender information is present (the customer has not swiped his/her card, etc.), the clerk should instruct the customer to enter their payment information.
The customer is then prompted to enter a cash back amount. The amount (if any) is limited by the option "Maximum amount cash back on debit card."
The combo device displays the transaction total (which includes the transaction total plus cash back) for the customer to review.
The customer approves or rejects the total.
If the customer accepts the total, POS passes the transaction information to ProtoBase for payment processing.
If the customer rejects the total, POS returns control to the clerk, who can adjust the amount (i.e. if the sale was rung incorrectly), choose another form of tender, or void the entire transaction.
If the customer approved the total, ProtoBase approves or declines the transaction.
If ProtoBase approves the transaction, a receipt or invoice prints, and the cash drawer opens if the customer specified a cash back amount.
If ProtoBase declines the transaction, the clerk is returned to the beginning of the tender process, and can either try the same tender again, or select a different tender type.
