Voting computers print out a report that says either there was no fraud or there was fraud.  If there was no fraud, the following code, for example, is printed out:

372636473262626383882726111737382626173

If there was fraud the following code is printed out:

372636473262626383982726111737382626173

Note that the two codes are identical except for one number in red.

Now, here is a page-one printout for a fraud-free vote:
