Virtual cards are an additional benefit offered to collectives through some hosts. Hosts create virtual cards and assign them to a Collective. Anyone with access to that card can then use it to make payments on behalf of the Collective. This is particularly useful for covering recurring costs like hosting a website.

@semble.so I'm experimenting with creating a Collection of links and resources that would normally be in the show notes of my podcast episode. Not sure it makes sense to include a guest's profile (i.e. university profile page or Bluesky profile) as a Card. What do you think?
