I dont copy cards that often so I have to remind myself of the features once in a while, but it seems to be fairly accurate, and robust. Definitely does what I need it to do.
Because business cards vary so much you do have to watch that it interprets correctly before telling it to save the contact since a little editing may be in order from time to time.
Comes in very handy though at large conferences where theres a lot of cards wont be going on, save a lot of time loading all those card you picked up at the local show
