What Is a POS Terminal?

A Point of Sale (POS) terminal is the electronic device used to process card payments. At a petrol station, POS terminals are typically located at the cashier desk inside the forecourt shop, and sometimes on portable handsets used by attendants at the pumps.

Types of Card Payments

MethodHow It WorksWhen Used
Chip and PINCustomer inserts card into chip reader; enters 4-digit PINMost common method for all amounts
Contactless / TapCustomer taps card or phone on the terminal’s contactless readerSmall amounts (typically under R500)
SwipeCard is swiped through the magnetic strip reader; customer signs slipOnly if chip is damaged or terminal chip reader is faulty
Mobile wallet (Apple Pay, Samsung Pay)Customer taps phone or smartwatch; transaction approved via biometric on deviceWhere supported by the terminal

Processing a Card Payment — Step by Step

  1. Enter the correct transaction amount on the POS terminal — double-check before proceeding.
  2. Select the transaction type: Purchase (not refund or void).
  3. Hand the terminal to the customer (or bring the mobile terminal to them at the pump).
  4. Customer selects their payment method: Credit, Cheque or Savings account.
  5. Customer inserts card and enters their PIN (or taps for contactless).
  6. Wait for the terminal to show “Approved” — do not release fuel or goods until approval is confirmed.
  7. Print the receipt — hand one copy to the customer; retain one copy for station records.
  8. Ask: “Would you like a printed receipt?” — not all customers do.
⚠️ Never Do These

  • Never enter an amount higher than the transaction total — this is fraud.
  • Never allow customers to show you their PIN — you should never know their PIN.
  • Never process a card payment if the customer is not present and watching.
  • Never retain a customer’s card — hand it back immediately after the transaction.

Handling Declined Transactions

A card can be declined for many reasons: insufficient funds, daily limit reached, card blocked, incorrect PIN entered too many times. Handle declines with discretion:

  • Inform the customer quietly and privately: “I’m sorry, the card has been declined.”
  • Do not announce the decline loudly or in front of other customers.
  • Offer alternatives: “Would you like to try another card, or would you prefer to pay cash?”
  • If the customer believes it is a terminal error, try processing once more — but if it declines again, the customer should contact their bank.

Void and Refund Transactions

Transaction TypeWhen to UseWho Authorises
VoidTo cancel a transaction on the same day before batch settlementSupervisor / manager
RefundTo return money to a card after the transaction has settled (next day+)Manager only — never processed by an attendant without approval

Always call your supervisor for void or refund transactions — do not attempt these on your own.
