White House Press Briefing, March 12, 2021 – Jeffrey 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…”

Grand Prairie, TX — 03/29/21 — A small minority-owned business in North Texas has developed a Secure SMART Health Card solution that stores encrypted vaccination records and identity authenticators via a proprietary SecuSeal™ that is similar to a QR-code but more intricately encoded, tamper-proof and secure. This new vaccination credential can be accessed and validated digitally. Or, it can be conveniently stored directly on printable paper, plastic cards, or sticker labels to facilitate the inclusion of those with no digital access.

The rapid vaccination of the population will gradually reduce the need for COVID-19 tests and will rely more and more on proof of vaccination. Assuming that it will become necessary to show proof of vaccination, this cardboard card can be improved at a small cost vs. creating a whole new secure document to facilitate the return to safer domestic and international travel and to public services including restaurants, bars, hotels, etc. This will certainly help mitigate the risk of contamination and the spread of Covid-19 or other contagious diseases.

Using the standard COVID-19 Vaccination Record Card from the HHS/CDC, Sandia International, Inc. 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 the identity of a vaccination cardholder requires a simple read of the digital seal that brings immediately the picture of the cardholder for a visual 1:1 verification, online and offline.


SecuSeal is based on SealCrypt™ technology adapted as a vaccine credential authentication solution that combines simplicity, ease of use, economy, security, and accessibility for all income levels.

Sandia International has a 20-year history of designing and managing government identity programs including PRC (Green Card) and EAC Programs in the US. It provides advanced processing toolspment, personalization tools and supplies for the plastic card and ID industries -
