Now that new credit card regulations are in place, card companies have become more transparent about explaining to consumers the mechanics of credit card use. The new laws that went into effect in February of 2010 were passed to help protect consumers from being overcharged on their credit cards, having their payments credited too late, or being forced to pay extra steep interest rates on their card balances.
The new credit card laws require, for example, that card issuers apply payments made by cardholders differently than they used to. So rather than the card companies charging higher interest over a longer period of time the money paid on a credit card can be applied sooner toward debt reduction.
