Swipe my phone: UK to use health service app as vaccine passport

Britain plans to use a National Health Service phone app as its COVID-19 'vaccine passport' certificate that will allow its population to travel internationally this summer, Transport Secretary Grant Shapps said on Wednesday. Countries around the world are looking at a host of options that will serve as proof of COVID-19 vaccinations to allow travel, though airports, border agencies and airlines are worried there will be no clear global standard that will be accepted at all borders. So-called vaccine passports could range from a digital certificate with a scannable QR code in the European Union, to a National Health Service (NHS) phone app in the United Kingdom, or a humble piece of paper in some other countries.
