We have the Corona passports here, here being Denmark.
To go to a pub, restaurant, amusement park or hairdresser and a lot of other things, you have to show a negative corona test less than 72 hours old, a finished vaccine or proof that you have had corona less than 12 weeks ago and have been tested negative afterwards.
There have been surprisingly few complaints, the complaints have been about the rule that you have to reserve a table 30 minutes before, both in pubs and restaurants.
