Today is election-day in Germany. Here's how elections are done in Germany:

5. You can't... I't not allowed to not get an official ID

they have a voter ID law [..] If you don't get an official ID, you don't register to vote.

Everyone is required to own an official ID (passport or ID card/Personalausweis) in Germany. You are also required to notify the government about your place of residence and keep the government updated when you move to another place. So every citizen (who hasn't lost their voting rights and is 18+ years of age) can vote simply by taking the notification letter and going to the polling place, which often can be reached within a few minutes walking distance, because everyone has an ID card anyway. It's not a technique to reduce turnout.

Vote early, vote often, and vote in pencil so we can correct your mistakes

From 8am to 6pm, every citizen is allowed to monitor our elections. Then everyone is allowed to monitor the counting process. Then you can check the final results to see if the precinct's results were submitted correctly. It's pretty much tamper-proof, or tampering would at least be easy to detect. (If nobody cares, then of course they can go and change votes when nobody is looking. But we're allowed to look, and usually there are members of at least both major parties at every polling place.)
