Indesign can generate a vcard using either: "Business Card" or "Plain Text".
Business Card type has one field for a URL.
Plain Text type (with proper vcard code) can have as many URL entries as you like.
One advantage with Plain Text is you can use this type in a datamerge workflow. A disadvange with the Plain Text type is this code is not readable on as many devices as other types of QR Codes.
Another thing to keep in mind, even though extraneous information like social media links can be included in the vcard text, the information doesn't always make it to the Contact Book after scanning.
