Swiss vote places right to use cash in country’s constitution

I think I read somewhere a few months ago that Switzerland (or their central bank) plans to pursue their partnership with GNU Taler. After a quick search it also looks like TWINT is a fairly popular and well accepted payment system in Switzerland. Afaik it’s mostly an alternative payment system so they’re not fully at the mercy of Visa/Mastercard. Which is sadly something most countries don’t have.
