A paper card has a tangible charm. A digital card is easier for a team that is spread out. Which is better?
Effort
Paper: someone carries it around the office. Digital: one link, everyone writes when it suits them, also from home.
Photos and extras
Digital cards hold photos in frames and a slideshow; a paper card has a few lines of space.

The personal touch
Handwriting is personal, but a handwriting font in a digital card comes close.

Keepsake
Paper sits in a drawer. A digital card can be downloaded as a PDF, or printed as a photo book.
Our take
Use paper for a very small group in one room. Use digital for everything else, and hand over a printed version at the party if you like both.
