what is this?

also from Hugh:



Credit Card Insert
A woman at work was seen putting a credit card into her floppy drive and pulling it out very quickly.
When I inquired as to what she was doing, she said she was shopping on the Internet and they kept asking for a credit card number, so she was using the ATM 'thingy.' 

I get that she was too dumb not to know it's not an ATM, 'cos ATMs are not at work - but what is a "floppy drive"? Her tits?
