Fake vaccine cards

With more and more venues, employers and institutions requiring proof of vax, an industry that sells fake vaccine cards is cropping up. And knowing that anti-vaxxers have no morals whatsoever, given they are already willing to sicken and kill other people by irresponsibly spreading a pandemic, we can rest assured that instead of getting the vaccine to enter aforementioned venues they will buy one of these fake cards instead. So proof of vax can no longer be trusted unless and until we have an easy way to verify them on the spot. The digital vaccine passports just ask you to input your card, which can be faked, so that is useless.
