In SCV one obtains 2 pieces of paper which are needed to cast a vote.
A voter can check if her/his vote is counted and at the same time the choice will remain secret.
Ballot - one can obtain it during in-person registration, by mail or by email - depending on the elections. It is generated by Election Authority. Ballot contains a permuted list of candidates/voting options.

| Coding card is prepared by different authority, so called Proxy. Thanks to a coding card, your PC does not know who you vote for.

In the second step of vote casting, one can see a table
which does not contain any voting option/candidate.
This is because a voter cast her vote through a server
run by Proxy - Proxy does not know the
permutation used on the ballot.
Thank to that, your PC does not know who you vote for
(in the real elections you obtain your ballot in the office,
in this elections you can fetch your ballot on the different
PC than you use to cast a vote).

If you align a ballot over the buttons then you see a picture similar to this:
To cast a proper vote, one has to choose a column corresponding to Y (from the coding card) in the row that corresponds to our choice (from the ballot).
In every other row one has to choose fields that correspond to "n" (from the coding card).
Below, an example of vote for the candidate that is in the 2nd row of the ballot (Candidate 1).
After casting a vote, Proxy server changes your choice (based on the serial number of the
coding card in following way: all no's "n" chosen are replaced with "x", all other fields remain empty ("ThreeBallot" form).

In the last step of vote casting you can choose one of the columns (A/B/C/D)
for verification. You can print it together with a string that confirms vote cast - it is your receipt.
The list of the receipts is published after elections. Check if it already
appears there and if agrees with one you obtained. If so your vote was properly counted (with high probability).
