There are so many different types of card out there that I thought it may be useful for someone to have a small explanation on some of them, so I decided to write this brief article.

First thing to know is that, no matter what type of credit card you may choose, there will be two

main options: fixed interest rate or variable interest rate.

While fixed-rate cards carry interests that remain the same no matter what you buy with it, those interest rates are usually very high, sometimes as high as 20 percent.

In the other hand, cards that have variable rates are known to be cheaper on the long run; the rates (which are calculated according to a special mathematical formula, which depends on the card's issuer) often remain lower that those of fixed rates cards, and therefore represent a more convenient choice.

If you are looking for lower rates on your credit card, you have two options: ask your creditor for a smaller number or go out there shopping for a lower-rate credit card. With the huge amount of different credit card issuers, the fierce competition between them may be a determining factor for you to get a lower rate on your card, so if you are used to your card, or if you are comfortable with the acceptance and usability of it, you should try asking your issuer for a more convenient rate.

However, if you feel that it may be easier to switch cards, then shop for a new one, looking for the best deal you may find. Some creditors are offering cards that carry interest rates as low as 8.5 percent. However, have in mind that sometimes lower rates card's conditions may be harder to reach than others; but if you have a good credit then you should give it a try.

So, have this in mind if you are looking for better rates, whether you have a retail card, a bank card, a secured card or any other.
