1. Vinnie the Votebuyer knows the _layout_ of the ballot. He only needs
to see that the correct box is punched/marked. Or that the screen
version has been checked.
Pretty easy to see that "Bush" has been marked instead of "Gore."
(For a conventional ballot. For a printed receipt is likely in the
extreme that the text will be large, at least for the results.)
2. I don't know about cellphone cameras, but my 1996-vintage one
megapixel camera has more than enough resolution, even at the "not so
great" setting (about 360 x 500) to pick up text very well. (I used it
to snap photos of some things with labels attached, for insurance
reasons.)
3. If Vinnie is serious about this votebuying (I'm not even slightly
convinced this would happen nationally, for obvious logistical and "who
cares?" reasons, plus the inability of Palm Beach Jews to punch a
conventional ballot, let alone work a digital camera and send the
images to Vinnie), he can provide a camera he knows will do the job.
Google shows that as of May 2003 the high-end cellphone cameras use
CCDs with 640 x 480. This will become the baseline within a short time,
certainly long before any of the "receipt" electronic voting systems
are widely deployed.
(e.g., this article at

200305_Easy_Snapping.php>)
But the resolution of today's very inexpensive digital cameras, and
probably those in today's cellphone cameras, is more than enough to
handle a ballot or reasonable-font receipt.
