Card-shaped USB drive
It is a USB thumb (or I should say "card") drive from TopTech Products called a Slim Data USB Card. This is a really slim USB drive housed in a case that has the same physical shape as a regular credit card, but is just a tad thicker. When you want to use the drive, you just fold the card in half to reveal the USB connector.
