Credit cards are very important and integral part of our life. If you have to purchase grocery or get a glass of juice, we all know that we have to get our credit card charged for that transaction.

And while we do all those daily chores, in the backdrop we always remember that there are credit card machines for business on which the merchant does some magic and we get our bills paid, but have you wondered how do these credit card terminals work There are three ways how your Credit Card can be swiped at a credit card terminal

One of the foremost methods that have been ancestrally used is to charge Credit Cards by swiping the Card in the swiping slot of the credit card machine for business. When the credit card is swiped the machine picks up the customers Card number and then sends it for an approval to the Credit Card Company through phone line or cellular networks. Once the approval is obtained your dues are paid and you get charged for the payment.

But sometimes there are some Credit Card Terminals which do not read the credit Card number when swiped and the merchant then keys in the Credit Card number to make the transaction. Now when we talk of new inventions in other spheres of life we should be aware that there is some metamorphosis happening in the world of credit card terminals as well. The newest method is instead of a swipe, the Credit Card Processing Terminal uses radio frequency waves to successfully enable the transaction. The merchant just need to wave the customers Card in front of the Card reader and the transaction is completed. And to top it all, there are some free credit card machines as well for the benefit of the merchant.
