I could access my covid pass on my phone (assuming I could remember my password at that moment!), but the only photo ID I possess is my passport, which I'm certainly not about to start carrying around with me on a regular basis, as it won't fit in my purse.
I've never had the photo part of a driving licence, having never needed a new licence since they were introduced. I suppose I will have to finally get one if proof of ID is going to be needed on a regular basis.
I find anything that requires a passport-style photo such a hassle though - getting an acceptable photo is always such a palaver.
What still bemused me is that many people seem to think that the little cards you are given when you have your vaccinations are the 'proof' of their vaccine status,
