The Roles of a Credit Card Reader
To use a credit card, a credit card reader has to be used and since you are one of those who owns a credit card, it is worthwhile to know how this equipment functions. A credit card is the important component part of the process in transacting our businesses using credit cards. In order therefore to accept your purchase, a credit card reader will use your card, and note that this machine can also read employee cards, customer cards and gift certificates.
It is undeniable that the use of credit cards is already integrated in our business world, and the credit card readers become a part of this process by taking part in reading and processing the cards to finish a transaction. The credit card reader’s purpose is to get the information from the credit card, pass on this information in order to check if the credit card has enough money to cover the purchase of the owner of the credit card.
By understanding the features of a credit card reader, we will be able to understand how it works and we will describe it briefly here.
Check out the back of your credit card and you will notice a shiny black stripe. That shiny black stripe contains important information that is being read by the credit card reader, and this information will confirm or not the transactions.
The act of swiping your credit card will trigger the reading of information embedded in the shiny black stripe, and then the information is sent by the reader to the central tracking and billing system that process the information to the credit card company.
After getting the information, the credit card company will confirm to the issuing bank if the card is legitimate, if the amount to be purchased can be covered or if the credit limit of the card is already way below and thus sale is negated.
A basic credit card reader is composed of a magnetic stripe reader, a keypad used to enter information, and a tiny display. A credit card reader can be attached through a keyboard wedge serial port or USB, and may have a built-in printer, or attached as a separate unit.
Among the several types of displays in credit card readers, the bigger display is better since you can view more information immediately. Having a backlit feature in a credit card reader is favourable also especially when the reader is used under low light surroundings.
With regards to the keypads feature, there are differences in the size and keys with the bigger keypads used more to enhance its use. With commonly used utilities, having more keys will be a preference to set aside own key for commonly used utilities.
