1. Card Reader: The card reader is the primary component of a credit card terminal. It reads the information stored on the magnetic stripe or chip of a credit or debit card. The reader uses magnetic or chip technology to extract the necessary data, such as the cardholder’s name, card number, and expiration date.
2. Keypad: The keypad allows the cardholder to enter their personal identification number (PIN) for added security. It also enables the input of transaction amounts and other relevant information.
3. Display Screen: The display screen provides visual feedback to the user. It shows transaction details, prompts for PIN entry, and displays error messages if necessary.
4. Printer: The printer generates receipts for both the merchant and the customer. It prints out transaction details, including the date, time, amount, and merchant information. The customer’s copy is handed to them as proof of purchase, while the merchant retains their copy for record-keeping purposes.
5. Communication Interface: The communication interface allows the credit card terminal to connect with the payment network. It can be a physical connection, such as an Ethernet or phone line, or a wireless connection, such as Wi-Fi or Bluetooth. This interface enables the terminal to transmit transaction data securely to the payment network for authorization and processing.
The Process of Credit Card Transaction
Now that we understand the components of a credit card terminal, let’s explore the process of a credit card transaction. The transaction process involves several steps, from card insertion to authorization and settlement. Here’s a breakdown of each step:
1. Card Insertion: The customer inserts their credit or debit card into the card reader of the terminal. The card reader then reads the information stored on the card’s magnetic stripe or chip.
2. Transaction Initiation: Once the card is inserted, the terminal prompts the customer to enter the transaction amount. The customer can either enter the amount manually or select it from a pre-defined list of options.
3. PIN Entry: If the transaction requires a PIN for verification, the customer enters their PIN on the keypad. The terminal encrypts the PIN and sends it securely to the payment network for verification.
4. Authorization Request: After the transaction amount and PIN (if required) are entered, the terminal sends an authorization request to the payment network. This request includes the cardholder’s information, transaction amount, and merchant details.
5. Authorization Response: The payment network receives the authorization request and verifies the cardholder’s information and available funds. If the card is valid and has sufficient funds, the payment network sends an authorization response back to the terminal.
6. Transaction Approval: Upon receiving the authorization response, the terminal displays a message indicating whether the transaction is approved or declined. If approved, the terminal proceeds to print a receipt for the customer and the merchant.
7. Settlement: Once the transaction is approved, the payment network initiates the settlement process. This involves transferring funds from the cardholder’s account to the merchant’s account. The settlement process typically occurs within a few business days.
Different Types of Credit Card Terminals
Credit card terminals come in various types, each catering to different business needs and preferences. Let’s explore some of the most common types of credit card terminals available in the market:
