Will they expect a photo for my id to be used? Photo for vaccination card seems to be taken. Didn't want to bring too many things to the event. Just in case I lost it.

Physical photo ID required. Photo of vaccination card is accepted.

They will check for both vaccination card and ID. If you're asking if you can take pictures of them and use that then i don't know. I think they do accept photos for vaccination cards though.

they checked my photo ID and my vaxx card

Physical ID required. Vaccine card image ok

You need to have a photo ID, not a photo of your ID.
