If you happen to own one yourself, then the black shiny stripe at the back of your credit card may be noticed by you a few times already. This stripe part of your credit card is the particular part that is being read by the reader when your card is swiped. Vital information that confirms if you will be able to make a purchase transaction is what is being contained in this particular part of your credit card.

Your credit cards must be swiped so that the data stored in the stripe will be sent to a central billing and tracking system that will then be able to send the necessary information to the credit card company and perform other vital functions as well.

When the issuing bank sends a notification to the credit card company, the credit card company then validates if the credit card is legitimate and if the amount being issued is either below or above the credit card holder’s spending limit.
