I won't add a picture to show what I'm about to describe, for reasons that will become obvious.
The NHS App has been displaying my Covid vaccination details under the section Health Record, Medicines, Acute Medicines, since I had the first jab in February.
My expectation was the App would gain a barcode or QR code linked to that existing data, for use at borders, airlines
Last week the App's Home screen gained a "Check your Covid vaccination record"
When selected, the dates, brand and batch number details are all diplayed on a new screen
I imagine it's this screen you're expected to proffer to any interested third party, border staff, airline staff, etc
But the screen is devoid of any personal information whatsover.
Anyone could display someone else's screenshot, and it would appear to be the real app!!
If you have the app, give it a try. See what I mean.
