Credit Cards

In this article we will look into the background on debit card systems and what they actually are.

A debit card provides the user with an alternative payment method in place of cash when making a purchase. Although it is similar to a credit card it is more similar as to if you were to write a check as these funds will be withdrawn directly from your bank account. In some cases these types of cards are referred to as check cards.

It works by the card being swiped through a card reader or inserted into a chip reader. The merchant will then usually enter the amount of the transaction and after which the customer will enter their account/pin number. There is usually a short time delay between this information being entered into the reader and it then contacts the computer network in order to verify and authorize the transaction that is taking place.

You may find that in some countries this card is multi-purposed and can also act as an automated teller machine card. This then allows the user to withdraw cash at any ATM. Plus it may also be used a check guarantee card (although many countries now are relying on the chip and pin system today). Often when using a debit card the merchant may offer you a cash back facility which means the user can withdraw cash along with any purchases that they have made.

Today the use of debit cards has become wide spread in many different countries and has now taken over from people using checks instead. Just like credit cards the debit card is now being used widely for any telephone or internet purchases that people make. But if anyone is in doubt about how many people are now using a debit card you only need to going shopping at a peak time, say last day shopping before Christmas. Because of the volume of transactions that are being made using debit cards can sometimes overload the bank networks.

Hopefully this little background on debit card systems has helped to provide you with a better understanding of what they do and how they work.
