Many countries have some sort of photo id&#x27;s,  think of driving licenses. What&#x27;s odd here is that they have to wear it in plain sight and use it all the time. A company badge is a credential valid only within the company, this is valid across the country for all kind of purposes. I won&#x27;t feel comfortable using my passport to open doors. It&#x27;s disproportionate to the importance of the credential. There are years I don&#x27;t use my passport at all.
