Card easily. Its convenient and honestly. Some of the cash I've been given over the years looks like it's been pulled out of a used litterbox. I don't know what some people are out there doing with their cash but I've been given some disgusting looking dollar bills over the years. Now I can just tap my card, go and not worry about having to pour an entire bottle of hand sanitizer on my hands after touching cash that looks like it's been living in a sewer.
