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.
