Swiss voters have narrowly approved a plan to introduce voluntary electronic identity cards. With all votes counted, 50.4% of those who voted said yes to the proposal, while 49.6% rejected it.

The closeness of the ballot is a surprise. Opinion polls had suggested up to 60% backed digital IDs, which also had the approval of the Swiss government, and both houses of parliament.

This was Switzerland's second vote on digital IDs; an earlier proposal was rejected in 2021 amid concerns over centralized data storage and control by private providers.

Sunday's revised proposal keeps the system in government hands, with data stored only on individual users' smartphones, making digital IDs optional. Citizens can continue using the national identity card, which has been a standard for decades in Switzerland.

To alleviate privacy concerns, a specific authority seeking information on a person, such as proof of age or nationality, will only be able to check for those particular details.

This decision comes after the UK government announced plans to implement its own digital ID system that would be mandatory for employment, raising similar concerns about privacy and data security.

Supporters of the Swiss system argue it will simplify various bureaucratic tasks, allowing for swift online processes for things like obtaining a telephone contract or verifying age. However, opponents fear the potential for compromised individual privacy, worrying about tracking and marketing misuse despite the new measures.

Switzerland holds a strong reputation for protecting citizens' privacy, exemplified by past banking secrecy laws, which were designed to shield personal finances from governmental oversight. Controversies surrounding Google Street View in the country further illustrate the public’s wariness regarding personal privacy.
