I wonder if the Minister for Digital Stuff has considered a smart telephone application as a means of verifying vaccination. With our technologically focused economy and education system, that would surely be a no-brainer. I think we spent a mere €146,000,000 on the COVID '19 contact tracing application which has proved extremely successful, assuming one considers minimising server traffic to have been the primary challenge in it's development. NTA have invested many many many millions of euros in it's TfLI taxi driver checking application and that works on many Android phones... of course, the negative nellies will focus on the fact that after a decade of development it doesn't work on all Android phones but that's just a bug, nothing a few million more Euros won't fix... probably.
