Financial website LendEDU.com used a handheld device by Hygiena called SystemSURE Plus that identifies germ scores for various objects to test cleanliness. The device found that credit and debit cards were dirtier than coins and cash on average. The higher the score, the more germs.
The device gave a higher germ score to credit and debit cards than it did the bathroom in New York City’s Penn station, which scored 163, while credit and debit cards on average scored around 285, whereas coins and cash averaged a score of 136 and 160 respectively.
So it may pay to be wiping down those credit cards with an antibacterial wipe no and again.
