Understanding How a Credit Card Reader Works and Its Purpose
Most people today use credit cards to make purchases, payments, and so on, and we should notice that machine which complete our transactions using credit cards which is called the credit card reader. In other words, we need a credit card reader to complete sale transactions, and it can also be used to read employee cards, customer cards and gift certificates.
Our business world today acknowledges the importance of credit cards in our daily transactions, and in connection with this, the role of a credit card reader is that to finish a sale or payment transaction by reading and processing the credit cards. A credit card reader is used to get information from a credit card and also in verifying if the credit card has enough money to cover the sale.
We will have more understanding about the operation of a credit card reader by knowing some basics of its operation first.
Looking at your credit card, you will notice a shiny black stripe at the back of the card. The stripe part is the part that is being read in your card that will tell valuable information that will validate your transaction. Know that when your card is swiped, the data embedded in the black stripe will be sent to the central tracking and billing system that will then process in sending the information to your credit card company. Once the credit card company receives the information from the issuing bank, it will now be determined if the owner of the card is valid for payment or if the card owner is already way below credit limit.
A simple credit card reader is basically composed of a magnetic stripe reader, a keypad for entering information and a small display. A keyboard wedge serial port or USB can be attached to the reader and it can have also a built-in printer or a separate unit.
There are some types of displays of a credit card reader, one is the bigger display which can show more information at once. In low light surroundings, to have a backlit display of your reader will be advantageous because you can still use it clearly.
There are a number of sizes and keys in the keypads of the reader, and the bigger keypads prove to be more easy to use.
Before purchasing a credit card reader, it might help to take note of some features before buying it. One feature is if the reader can be attached to your computer through a port or USB especially if you are processing online. Another feature to watch out for is the ability of the reader to customize key functions and to download data to your computer. Check if the reader has a bi-directional reading capacity that will save you time, meaning it can read data left to right and vice versa.
