There are two separate issues.

o The tabulation should be done on sheet-fed scanners that can
handle a hundred or more sheets automatically.

o Voters should verify their ballots on stations optimized for
single-sheet use.

One model is to have a sheet guide that would accept the ballot
in its folder, with a read head fixed in place above it. This
type of configuration is used in some libraries to read bar
codes on books and library cards simultaneously. Note that a
sighted poll worker (under observation to prevent hanky-panky
like opening the folder to read the ballot) can place the ballot
on the station and give the voter the headphones.
