Membership Card tied to Individual or Household account?

We are a membership organization and looking into options for our membership card setup. Like most membership orgs, we have several membership levels and some of which that allow 2 cards per membership and various guest entry privileges .

Are any organizations out there tying membership cards with barcodes at the individual level rather than the household? I would love to know your experience and any pros/cons you have encountered. Is the barcode generated out of Tessitura?

We track all contributions and associated membership at the household level. Thank  you!
