Agreed, a growing number of countries now have a feature on a HealthHub mobile app which people can use to access their official vaccination record (& any Covid test results), and a tracer QR code which can be used when checking in to a hotel or flight or restaurant etc to show the person has been fully vaccinated.
Those little bits of paper we're given can easily be lost or become illegible & will hardly pass the grade when travelling overseas through different countries.
And what happens when people have lost them, thousands of new ones being written ?
Countries are starting to allow people in who have been fully vaccinated & we're going to need something more official & difficult to forge than a little handwritten card.
