The fellow from Avante noted this and I 
  think that it is quite valid. The Hart system uses a brain box that creates a 
  printout with a random number that the voter enters into the DRE to get their 
  ballot to come up. These key numbers time out in ten minutes (adjustable, but 
  not removable). When the lines get long and voters don’t get to a DRE before 
  the key number times out, they go back to the judge and get a new one and try 
  again.
   
  In James’ example, a voter could get 
  someone else’s number (just by sneaking a peek) and vote twice. The voter that 
  arrives at the DRE and finds that his or her number doesn’t work will go back 
  to the judges and get a new one, and then vote. The judges would issue a new 
  one based on the idea that the voter’s key number had simply timed out. Even 
  if they were smart enough to figure out that it had been used to cast a vote, 
  it wouldn’t be that voters vote and a really hot argument would 
  ensue.
   
  When the election is tallied, the number 
  of votes will exceed the number of voters that came to the polls. However, by 
  that time there will be no way to figure out which ballot to 
  toss.

  Hart
   
  Paul,  
   
  I never really thought about this 
  before.  What if someone looks behind them at someone's PIN number and 
  uses that number to vote then vote's their own number?  Doesn't that mean 
  that someone can vote twice?  In a crowded polling place, this could 
  happen before it can be stopped.
