So how good is the printing on these keypad cards going to be and how long is the card issue period going to be?

If you are continously going to be entering the same 4 digit pin into the card, the buttons are going to wear and/or get dirty. The criminal who now gets hold of your card knows from the wear on the keypad which 4 digits are in the pin reducing the possible varients from 10000 to between 1 and 24 depending on whether numbers are used multiple times.

Ok you don't need a separate reader to generate the one time pin, but at least having the separate reader (unless you carry it with the card and so the worn key problem still applies) any criminal get hold of your card still has 10000 pin combinations to work through.
