Good enough for seeing what PIN was typed on the atm machine?

  Oh definitely. But ssshh

  You mean, so you can 1) mug the cardholder, and 2) try all the 4x4 combinations (or 5x5 for mine), which I believe will get the card eaten after a small number of failures? Seems like it would be much useful for snooping pinpad door lock codes, which often don't seem to care how many errors you enter in a short period.

    Good point. Real criminals attach an inconspicuous cam and a skimmer to the machine.

  New advice: after typing PIN, place your palm over the buttons to heat them all evenly.
