My lifetime experience with credit cards has been less than satisfactory. Much of the time I used credit cards for unnecessary purchases and later found myself with unwanted payments. Actually, having and using credit cards has negatively affected my credit rating because of a few missteps on my part and some rather dubious practices by the card-issuing companies which I disputed - to my detriment.
My sister, however, 6 years my junior, has fared much better, using credit cards with great discipline, carrying a small balance, using the cards for needed purchases and paying them off within the grace period at no interest. Thus has she achieved a stellar credit record over the years.
Obviously, how one uses credit and credit cards will in a large way determine one's credit rating, which carries great influence in today's highly-leveraged environment.
Credit ratings and records are used in everything from purchasing a vehicle, home, or establishing individual store revolving credit to employment and security screening. It's gotten to the point where three companies - Equifax, Experian and Trans-Union control our destinies to an unwanted degree.
