In googling the guidelines I came up with this:
https://www.cms.gov/Medicare/Medicare-Contracting/ContractorLearningResources/Downloads/JA0736.pdfThey need to have at least 1 feature from 3 categories (see link for details)

AC does have microprinting which, with laser printing, is supposed to be unable to be photocopied.
Technically the rules only apply to Medicare and Medicaid, but....
