The Features of a Credit Card Reader and Their Uses

We use our credit cards nowadays in our purchases and we might be wondering what is that machine where our credit card is plugged in. A credit card is the important component part of the process in transacting our businesses using credit cards. Aside from reading your credit card to complete a sale, a credit card reader also reads employee cards, customer cards and gift certificates.

Our modern world today is using credit cards to transact sales of products and services, and in order to finish the sale transaction, the credit card reader is used to read and process the cards. The information that a credit card reader gets from a credit card will then be passed on the system and will be verified if the certain credit card has sufficient amount to pay for the purchase.

In order to understand more on how a credit card reader functions, let us briefly describe to you its features first.

When you use your credit card, you will notice at the back that it has a shiny black stripe. When your credit is swiped on the credit card reader machine, that shiny black stripe is being read, and the valuable information that is stored there is important in validating the sale.

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.

A magnetic stripe reader, a keypad to enter information and a tiny display are the main features of a credit card reader. The whole system is connected in such a way that the reader is connected to a keyboard wedge serial port or USB, and can have a printer that is built in, or considered as a separate unit function.

Among the several types of displays in credit card readers, the bigger display is better since you can view more information immediately. There is also a reader with a backlit that proves to be advantageous when your reader is used under low lighted areas.

Keypads differ in number of sizes and keys, and generally, the bigger keypads will enhance the convenience in using. With commonly used utilities, having more keys will be a preference to set aside own key for commonly used utilities.
