This is good news. I hope governments around the world embrace it. For this, there has to be some security around preventing fake passes. The same people who come on here saying that they do not agree with imposed conditions may lie or cheat their way around having a pass before they are entitled to one. For this reason, I fear too many governments, particularly those who have had success in combating the outbreak, will simply stick to their own draconian systems far longer than is necessary.
