So, how does it function really?
Have you ever heard an employee ask the following: Will that be American Express, MasterCard, or Visa? This exact question is what is usually being thrown by merchants on their credit card holder clients who have now made their purchase and ready to pay them. If you have a credit card yourself, then you might have seen a lot of times from the back of your credit card a black shiny stripe. When your credit card is being swiped, this particular stripe part at the back of your credit card is actually what is being read. 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.
There is a need to swipe your credit cards on the reader so that the information contained in the stripe is then sent to a central billing and tracking system where such as system will then send the necessary information to your credit card company.
Once the credit card company will receive the notification from the issuing bank, it then provides a confirmation whether the credit card is legitimate and whether the amount being issued is still above or below the spending limit of the credit card holder.
