Under the revised proposal, the new system would remain entirely optional and in public hands, with the data on the electronic IDs stored on users' smartphones rather than centrally. Citizens can still choose to rely on a physical national identity card, which has been standard in Switzerland for decades. To ease privacy concerns, a particular authority seeking information on a person – such as proof of age or nationality, for example – will only be able to check for those specific details.

Trojan horse.

Agree that's a danger. But I hope the Swiss decentralised political system prevents creep of centralisation. It did that in the first round.
