How do I transfer tickets on my Apple wallet to someone else’s Apple wallet

Please review the Apple Support article I linked below.

I doubt you can share an insurance card, but worth a try.

You’ll have to ask your insurance company as it’s their app or website which manipulates the cards in wallet.

If it is possible you will see the "share" button up at the top after you tap the card in your wallet. Just hit that and then you can send it a number of ways.
