CDC vaccine record cards != vaccine passports. Per the article and my earlier comment, the latter will incorporate database records linked to government issued IDs and “signed with encrypted keys using a QR code system similar to that adopted in Israel.”
That kind of system is not 100% foolproof, and forgers will make some money off the suckers before enough of them find out the counterfeits are useless (I give it 8 weeks at most).
On the whole, though, the passports/passes will help private businesses and foreign governments solve the very real problem of how to bar anti-vaxxer morons who think they’re entitled to do whatever they please despite their science denialism and irresponsibility.
I understand that the use of the term “passport” can be confusing, so this article might give you a better understanding of what’s happening in this regard.
