I migrate a static website to kirby for a client. Every employee has his own page with some personal data and the visitor can download his vCard. Does it possible to generate a vCard (vcf file) with Kirby?
Sure it is. I couldn’t find a Kirby plugin that does something like that with a quick Google, so it will probably require some custom coding with a route (https://getkirby.com/docs/developer-guide/advanced/routing) and some understanding of the vCard file format. You can probably use an existing library to generate the actual vCard content (First Google hit: https://github.com/jeroendesloovere/vcard).
So, it really depends on your development skills.
