Emergency access to RPV by others

Many people already share their login with staff at other hospitals, surgeries, or units.  Some people have asked whether it could be made possible for others to see your RPV records in an emergency, at a time when you aren't able to give permission because you are too unwell.

Would this be a good idea?

Alternatives:  show your RPV login in a card in your wallet, or even on an alert bracelet/necklace.

If we were to build it into RPV, we would have to work out how to make it simple while keeping it safe, how to tell you later who had accessed it, and whether to make this available for everybody, or only those who wanted to.
