Abstract
Systems, methods, articles of manufacture, and computer-readable media for verification of medical status using a contactless card. An application may receive a request specifying a subject and a medical condition. The application may receive a cryptogram from a contactless card. The application may receive a decryption result from a server and determine that the server decrypted the cryptogram. The application may receive, from the contactless card, a medical attestation, a digital signature of the medical attestation, and a public key of the digital signature. The application may decrypt the digital signature based on the public key of the digital signature and verify the medical attestation based on the decrypted digital signature. The application may determine, based on the verification of the medical attestation, that the subject is immune to the medical condition. The application may output a result that the subject is immune to the medical condition.
