Young man obtains voting ballot under Attorney General Eric Holder's name

Branson, the cash cost is not an issue.  Because of the poll tax amendment and the Voting Rights Act, the various voter photo laws all provide some option for obtaining the needed ID without paying cash.  This is one of those meaningless wedge issues that both parties like to push.

There is very little demonstrated voter fraud, examples as such as what krazen could be dealt with without requiring a photo ID (SC law at present requires that an ID be presented, of which the voter registration card with no photo is one of the options), and these laws leave open other avenues to fraud (such as obtaining absentee ballots by mail) that aren't addressed by photo ID.

Conversely, despite the claims of voter disenfranchisement, very little of that would happen under voter photo. For the most part, difficulties in obtaining photo ID are had mainly by people in their 50s and older who were born in the era before issuing birth certificates became pretty much automatic.  The elderly are generally covered by more liberal rules in being able to vote absentee, and I'm not aware of a single jurisdiction that requires a photo ID to accompany a mailed in request for an absentee ballot.

If it were not for the fact that those affected most come from groups that tend to vote Democratic, this issue wouldn''t get anywhere near the heated invective it does.

Just implement automatic/universal voter registration and throw out any votes that don't match up against the voter database (deceased, multiple votes per person, etc).

Oh wait, that would make voting easier and lead to tens of millions of more people voting. Can't have that right?

So you would throw out the valid vote along with the invalid one?

How do you determine which one was valid?

How do in-person voting systems currently deal with multiple votes per person?

I can't speak of all systems, but here in South Carolina the general rule is that absentee ballots must be received 4 days before the election.  This gives the election commission time to mark on the voter rolls that will be used at the precincts that they have received an absentee ballot for that voter and thus they know that they are to not hand that person a ballot if they show up at the polls.  There are procedures for a voter to cast a provisional ballot if they dispute that they cast an absentee ballot.

Also, if someone pulled the stunt mentioned in the OP here, they aren't supposed to get a ballot.  You are required to produce an ID and the poll worker must check the ID against the voter roll.  It just is that at present one of the acceptable forms of ID is the non-picture voter registration card that is currently in use.  If the poll worker failed to check the ID, they would be doing their job wrong.
