Cards for people with poor credit

There are many reasons why people can not get credit cards issued in their name.   Along the same lines there are places where you can not use cash and must present the plastic card in order to make a purchase.  What is a person to do if faced with both of the above.   To avoid the embarrassment of poor credit and no cards there are companies that will issue prepaid cards.  You decide how much you are going to need to charge on the credit card and then purchase a card for that amount.  The business will have no idea that your credit is bad and treat your purchase as a routine sale.
