Um, last I checked, phone cameras have really shitty resolution, usually
less than 320x200. Even so, you'd need MUCH higher resolution, say
3-5Mpixels to be able to read text on a printout in a picture.
Add focus and aiming issues, and this just won't work unless you carry a
good camera into the booth with you.
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 <http://www.what-cellphone.com/articles/200305/ 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.
