I'm not quite the target for this, but I'd value the ability to take age-ID (which for me is always my driving license) on my phone in some way.
I'll also say that I think you can get to Samsung wallet without unlocking your phone, though you need to authenticate to trigger payment, so it's possibly a way of not handing your unlocked device out.
I'm always weirded out by folk handing over cards to be taken to machines in other areas, too.
Edit: Huh, seems like there may already be a solution for me, [here] (https://www.postoffice.co.uk/identity/easyid).
