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. 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.

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.

Looking at your credit card, you will notice a shiny black stripe on the back of your credit card. 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 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.

Once the credit card company gets the information and confirms from the issuing bank that your card is legsitimate and has the amount enough to support your purchase, the credit card reader will issue the signal through a receipt.

A magnetic stripe reader, a keypad to enter information and a tiny display are the main features of a credit card reader. 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.

The display part of the reader comes in various types, with the bigger display as more favourable since you can view more information. When the credit card credit is used under low lighted areas, if your credit card reader has a backlit feature, it will then be advantageous to have this type.

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.
