According to a study by LendEDU, our credit and debit cards are actually the most bacteria-covered things in our purse or billfold! Even dirtier than dollar bills! The dirtiest credit card they tested was filthier than a door handle at McDonald's and a NYC subway pole. Credit and debit cards scored a germ rating of 285 compared to cash at 160 and coins at 136. Just for reference, a Penn Station public restroom as a germ score of 165 which is a whole lot less germs than a credit card! You can hear our fun conversation about it here...
