I agree with Carol on this. This is not easy as some say it is. First of all the vaccination card from the CDC is way too big to put in a wallet. I never carry a handbag so that’s not an option. when my husband and I take a taxi to different beaches (Not on the French side) we don’t take any ID with us or his cell phone. We like to go in the ocean together and would not want to leave a cell phone, a wallet and now a vaccination card on the beach. So when we went to eat lunch or have a drink we’d have to show a vaccination card so we would not be able to eat or drink. Yes, I know there are water proof wallets..we tried them. They don’t always work.
Not everyone has a cell phone. I don’t have a cell phone other than a little flip phone I keep in my car for emergencies. I have an iPad so I’d have to make a copy of the vaccination card on my iPad and schlep my iPad all over SXM? And it is a shame for restaurant owners, etc, who have to also act as police.
