In addition, another page on the same website says:

>The cantons of Neuchâtel, Fribourg, Thurgau and Basel-Stadt used Swiss Post’s previous e-voting system until 2019. The following cantons (among others) are planning to use the new Swiss Post system once this becomes legally and technically possible: [list of cantons follows]

A Swiss Post press statement says:

>Since the beginning of 2021, Swiss Post’s future e-voting system has been put through its paces by independent experts from all over the world. Another testing opportunity is now available: in addition to the ongoing test options, ethical hackers can now attack the e-voting infrastructure for a period of four weeks. This means that, for the first time, they can accurately simulate and target the vote casting process on the voting portal using sample voting cards. The aim is to detect potential vulnerabilities and rectify them in good time. Swiss Post expects to make its new e-voting system available for use by interested cantons during the course of 2023.

I don't understand why you must be so haughty (vide "Do the bare minimum research before posting please."). Certainly, you are correct for some definition of "Switzerland has an e-voting system" --- there is one under development, and it had been piloted for a limited time period. However, at the moment, it's only in the public testing stage, it's not officially recognized, cannot be used to cast votes, and there is no guarantee that it will get a green light. I think that's the more accepted definition of "to have an e-voting system", in which case the OP was right, and it was you who did not do adequate research.
