I see no rules saying you're required to bring a photo ID or have it verified, but I have been carded at events before anyway, so can't attst how that would go. Another problem I can see there is some venues (private card shops for example) probably won't allow masked or hidden faced people in the store, so that could be a problem outside the official ruleset.
Also, if you already have a Player ID you legally aren't allowed to have multiple, so unless you merge or discard the former, that legally wouldn't fly.
