When I renewed my driving license it was added onto the new one. Been on it for years anyway, but good to see the gov agencies being joined up like this.
It also ties in with blood donation and the Anthony Nolan Trust for bone marrow donation. Again done both for over 20 years. Never been asked for bone marrow, but they keep asking me back for blood. 57 arm fulls now.
EDIT: Not sure if they still have to ask your next of kin for permission before they can take your organs. It’s not exactly the best time to be asking and if you have already given permission, and it’s your body, there should be no requirement to ask.
I know there was some noise a few years ago about it, along the lines of some relatives refuse permission and possible organs are lost because a relative is too emotional to make the choice.
