Sandia International Launches more Secure, Private Vaccine Pass Technology

GRAND PRAIRIE, Texas, April 16, 2021  /PRNewswire/ — A first-of-its-kind, secure SMART Health Card solution that stores encrypted vaccination records and identity authenticators is now available from Sandia International, Inc., a secure identification technology provider based in North Texas. The card’s underlying technology is SecuSeal™, a proprietary solution that is similar to a QR-code but more intricately encoded, private, tamper-proof, and secure. This new vaccination credential can be accessed and validated digitally, online, and offline. It can be conveniently and securely stored directly on printable paper, plastic cards, or sticker labels to facilitate the inclusion into documents with no vulnerability of digital access. This is the first and only encrypting technology applied to a non-digital credential such as a vaccination card.

White House Press Briefing, March 12, 2021Jeffrey Zients – White House Coronavirus Response Coordinator:

“…as we increase the number of people vaccinated, we know some people may have a need to demonstrate that they are vaccinated…  Our role is to help ensure that any solutions in this area should be simple, free, open-source, accessible to people both digitally and on paper, and designed from the start to protect people’s privacy…”

An increase “vaccine passports” in the United States and globally is anticipated or already required, especially for domestic and international travel. Domestically, even if not required, a vaccine passport could exempt cardholders from strict testing and quarantine requirements. Sandia’s cardboard SMART Health Card can be improved at a small cost vs. creating a whole new secure document.

“We saw this opportunity to incorporate our decades of digital experience with SMART technology solutions for government use with increasing fraud protection through non-digital storage for this very sensitive vaccine authentication,” Alexander Ayanru, president of Sandia International.

Using the standard COVID-19 Vaccination Record Card from the U.S. Department of Health and Human Services and the Centers for Disease Control and Prevention, Sandia International adds a unique VDS  (Visible Digital Seal) after the first (or second) vaccination to seal the information with the owner present, creating a relationship between the Vaccination Certificate and the owner. Verification of a vaccination cardholder’s identity requires a simple read of the digital seal that immediately brings the picture of the cardholder for a visual 1:1 verification, online and offline.
