How is their electronic voting system transparent? I don't know much about it.
There are some electronic voting machines in a few towns but they are no better than elsewhere and will hopefully go away. Rather I was referring to the paper voting which is the main way to vote here.
Unicity: The 'one voter, one vote' principle.
Based on voter lists like elsewhere and the identity card to avoid impersonation.
Confidentiality: Each voter expresses his/her choice alone.
There is one ballot per candidate and you must pick one ballot of each before going in the voting booth. Behind the curtains you pick which ballot to put in the envelope and discard the rest of the ballots.
Anonymity: It is impossible to link a ballot to the voter who cast it.
The envelope goes into a transparent urn and gets thoroughly mixed with the others when the envelopes are taken out. Furthermore putting an identifying mark on a ballot invalidates it further guaranteeing a ballot cannot be linked to a voter.
Sincerity: The results of the election must faithfully reflect the will of the voters The ballots are counted by volunteer voters right at the polling station as soon as the election closes. That is ballots are not moved around and/or stored before being counted. Counting one ballot involves four volunteers, one who opens the envelope and passes the ballot to the diagonally opposite volunteer who reads the ballot aloud and two who write down the count. Volunteers are further watched over by election officials and party representatives. This just requires about 1% of voters to volunteer and the polling station results are announced to everyone present within about 1.5 hour.
Transparency: Voters should be able to verify that the election system is working properly.
Voters can keep track of everything from the moment the urn is sealed, and verifiably empty since it's transparent, to the moment the polling station results are announced (and after that parties can and do perform their own tallying to verify that too). Voters can also watch ballots being counted, or make sure the urn is not tampered with during the day, etc.
