Many consumers have a bit of confusion when it comes to distinguishing a secured credit card from an unsecured credit card. They both carry a brand logo from one of the major credit card companies and they both can be used anywhere that major credit cards are accepted. It is the behind the scene financial activity that determines the difference between a secured and an unsecured credit card. A secured credit card is a guaranteed VISA or MasterCard that has been secured by a deposit to the issuer's bank. Generally, you must deposit an amount, ranging from $300 to $5000, in a low-interest saving account or CD to secure the credit card. -------------------------------------------------------------------------------- You then receive a credit line for up to 100 percent of your account balance. Each creditor has its own requirements for how much you can deposit for your credit line. The creditor issues you a credit card by using your deposit as security.
