After receiving my second Pfizer vaccination, I was given a certificate with a QR code. However, when I went to the link from the QR code, the vaccine certificate only listed my vaccine name, lot number, and date given. There was no identifying information. Out of curiosity, I downloaded the mor prom app. I enrolled using my 13 digit ID number and my Thailand telephone number that is on file, beginning with 0. After creating a password I was successfully enrolled in mor prom. It then took me to a page that had icons including vaccine certificate, and when I clicked that, it took me to a vaccine certificate page that include all necessary information including personal identification. That should work overseas in other countries and through immigration That are utilizing digital vaccine passports.
