Simple, does exactly what it says on the tin. Works great as intended for credit cards. The card needs to be swiped in a stripe on the opposite side of the green light (unlike the reader I use). As some may not know, you must place your cursor in the credit card field on your computer for the reader to work. This may be why some reviewers complain that their readers don't work.
