That’s why I use both the terms “vaccine passport” and “vaccine pass”, which function similarly (QR codes, encryption, link to database, visual match with government-issued ID, etc.) but have different use cases (crossing international borders and getting into domestic venues, respectively). The former might be an acceptable substitute for the latter in a private business setting, or there might be combinations of the two.
For purposes of this discussion, we can generically call both “vaccine passes” to avoid further confusion about the concept on your part. Going back to the original point, “vaccine passes” will be more difficult to forge than a CDC card (or a high-schooler’s fake driver’s license) is.
