A vCard QR is static: the contact details live inside the code, so it works forever but can't be edited. Fine while your details don't change. When they do — new job, new number — everything you printed is out of date. A dynamic QR points to a URL you can update any time instead.
It's the standard contact-file format (.vcf) phones use to import contacts. Scanning the QR opens a save-contact screen with the details pre-filled.
