Vax Card in Caribbean?

[bhsolo]

I'm going to St. Thomas, St. Kitts, and Antigua on Explorer at the end of April. As I was researching exploring on my own I noted that a restaurant or two state you need to show proof of vaccination. For those who have been to those islands or others, can I show a photo on my phone or do they require the actual physical card? I'll have the actual card for getting on the ship but would prefer not to have to travel with it when going ashore, unless there will be an issue. 

 

Thanks for any insight!

We were at St. Kitts and others on NCL last month.  All the places we went were good with the photo on the phone, they really didn't even check ID to go with it.  They just have inspectors doing spot checks all the time to ensure they're at least asking.
