The Features of a Credit Card Reader and Their Uses
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. The machine that is used as a medium of processing our purchases when we use credit cards is called the credit card reader. Aside from reading your credit card to complete a sale, a credit card reader also reads employee cards, customer cards and gift certificates.
Our business world has taken in the use credit cards in order to transact sales of products or services, and to complete the process, the credit card readers do the reading and processing of these credit cards so that the sale transaction is finished. The role of the credit card reader is to get the information from the credit card, pass the information, and make verification if the particular credit card has sufficient funds to support the purchase being done.
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.
When you use your credit card, you will notice at the back that it has 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 purpose on the swiping of the credit card is to send the data embedded in the shiny black stripe to the central tracking and billing system, then it process the information and send 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.
The simple features of a credit card reader are the magnetic stripe reader, the keypad used to enter information, and a tiny display. A keyboard wedge serial port or USB is where the reader can be attached, and can have a printer that is either built in or separate unit.
The display part of the reader comes in various types, with the bigger display as more favourable since you can view more information. Having a backlit feature in a credit card reader is favourable also especially when the reader is used under low light surroundings.
There are various sizes and keys in a keypad of a credit card reader, with more advantage if the bigger keypads are used. With commonly used utilities, having more keys will be a preference to set aside own key for commonly used utilities.
