Voters in Switzerland are going to the polls on Sunday to decide on the introduction of electronic identity cards.

The plan has already been approved by both houses of parliament, and the Swiss government recommends a yes vote.

It is the second nationwide ballot on the issue after voters rejected the idea in 2021 amid concerns over data protection and unease that the proposed system would be run largely by private companies.

Under the revised proposal, the new system would remain entirely in public hands, and data on the electronic IDs would be stored on users' smartphones rather than centrally. The electronic ID would be optional.

Citizens can still choose to rely on the national identity card, which has been standard in Switzerland for decades.

To ease privacy concerns, a particular authority seeking information—proof of age or nationality, for example—will only be able to check for those specific details.

Supporters argue the system will simplify every aspect of life, allowing for faster bureaucratic procedures online—from signing contracts to proving age for alcohol purchases.

However, due to a long tradition of protecting privacy in Switzerland, many remain cautious. Laws around banking secrecy were designed to shield personal finances, and there are controversies regarding public surveillance, like Google Street View, which faces strict regulations.

Opponents of electronic ID cards fear the new system could undermine individual privacy despite introduced restrictions. They are also concerned about data potentially being used for tracking or marketing without permission.

Interestingly, the previous Covid ID, mandatory for restaurant access, may influence the current vote—many citizens were pleased to show it for freedom to socialize, shifting initial skepticism to acceptance.

While privacy fears linger, the perception that huge tech companies already gather personal data daily may lead voters to view the electronic ID as a manageable trade-off.
