These card terminals automatically transmit data, and will facilitate communication between the verification center and the customer. Some credit card terminals work differently from others, and require no input from the merchant. However, some credit card terminals are wireless, and will use either cell phone networks or Wi-Fi to send data for verification. This is necessary for them to transmit data for verification. Most credit card terminals are attached to phone networks, and they function in the same manner as a modem. If the card is approved, the merchant can provide their goods or services to the customer, but if the card is declined, they can block the sale. The information from the card’s magnetic strip will be sent for verification, which will return either an “approved” or “declined” message to the merchant. Many terminals also require a four digit code to be keyed in, as an additional security measure. When the card is swiped, the terminal will read the information on the card’s magnetic strip. Most terminals will come with a keypad and a slot where the customer can swipe their card.
Most stores these days have at least one credit card terminal, and larger stores can have dozens of them. These machines protect the merchant, because if the customer attempts to use a card that is expired, stolen or damaged, the payment will be denied and the merchant will avoid giving away their products for an invalid card. The purpose of the terminal is to scan the card, authenticate it and transmit the data. Credit card terminals are machines used by merchants to process credit card payments.
