Unless you have really good credit it may be difficult for many people to obtain a credit card. There are so many requirements for getting a regular unsecured credit card that it is incredibly difficult for anyone with bad credit to get a credit card and even if they do the interest rates are usually astronomically high. If you are one of these people who has less than perfect credit or even if you don't have a bank account of your own there are still ways to get a credit card with one called a "no bank account credit card", which is created to help people with bad credit. Unlike traditional cards these are easy to get and they help you build your credit back up and get your life on track.
These credit cards are prepaid or pre-loaded so that you are limited by the amount of money you give the company as collateral on the card. These are also known as secured credit cards. This is a good card for people who need spending limits, such as teens, college students, or other people who may be financially irresponsible. A secured card like this will help someone learn to manage their money better but will not allow you to get into debt since the card is secured by your own money. These credit cards work just like a normal card so if you need to reserve a hotel or rental car online or by phone you can use one of these just like a normal card.
Just like anything you want to do your due diligence and check out the company before you get one of these cards to find the best deal you can. Many of these cards will give you similar points, cash back, and other programs just like those of regular unsecured cards and if you have access to the internet you can probably get access to your account online. Look for cards that are widely accepted globally and also allow you to get ATM withdrawals.
Other features that you want to be sure the issuing company offers include no annual fees, easy accessible customer support, and low percentage rates. Even more so than with regular cards, customer support is crucial for these types of cards so if they don't have good support scratch them off your list. You want to be sure there is someone there when you need them.
Just do as I said and do some research for secured credit cards and if you follow the guidelines that I have given above you will find one that will work for you. Be sure that once you have narrowed it down to a few to compare charges, fees and rates so that you get the best deal you can. Just because your credit is less than perfect doesn't mean you can't get the benefits of a credit card.
