I haven’t read deeply into Apple’s standard for digital ID, but I would assume that it’s implemented the way contactless payment via Apple Pay/Google Wallet/other mobile wallets is — rolling tokens that are valid for a single transaction. Skimming attacks are also improbable given that you need to authenticate with FaceID or a passcode for every transaction. It’s not like the phone is constantly blasting out ID/payment card details.
