So, how does it work?
“Will that be American Express, MasterCard, or Visa?” Such a line is usually being the one thrown at credit card holders by merchants when they have decided to make a purchase. If you happen to be a credit card holder yourself, then you have of course taken notice of a shiny black stripe at the back of your credit card. This particular black part is being read every time you decide to make a purchase. It possesses the necessary information that is useful in validation every transaction of yours.
You swipe your credit card because the data in the black stripe will be sent to a central tracking and billing system. Such a system is capable of doing a lot of things, one of which is sending your information and transaction to your credit card company. If the credit card company will be sent a confirmation from the issuing bank, it then pushes through with one from two actions. First, the company ensures that the credit card is legitimate and provides confirmation that the purchase is just below the spending limit. On the other hand, the company may have to deny the transaction because the client is in serious debt and is already beyond his or her spending limit.
