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. Whenever we use our credit cards in buying and paying the products, a credit card reader is the machine that completes the process in the transaction. 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 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.
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. Upon swiping your credit card, the information contained in the shiny black stripe is read by the credit card reader and it will validate your credit card if it contains enough funds and allow transactions.
When your credit card is swiped in the credit card reader machine, the data embedded in the shiny black stripe will then be sent to the central tracking and billing system, and process the information sent to the company where the credit card belongs.
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. 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.
