Unsecured cards are cards that the bank issues when they believe they can trust you with credit without a deposit. These are harder to get. There are also pre-paid credit cards, which pretty much work as glorified gift cards that are accepted in all the same places credit cards are. These can be given out as gifts, company incentives, or purchased for yourself for uses such as travel.
There are also business credit cards. These cards typically offer incentives for company travel, office supplies, and the like, so businesses will want to place expense accounts on their cards. These can make life a lot easier for a small business when they are trying to separate their accounts so that they can accurately determine expenses.

With all these types of credit cards, it can be tough to make a decision. But I'm sure after reading this article you have a bit of a clearer idea on where to go when searching for credit cards. Best of luck!
