I never knew what a bootable business card was so I avoided those.
If you trim a cd so it's rectangle you end up with a business-card size disc which holds about 50MB. Their main drawbacks are that 1) nobody has a cd drive anymore and 2) people who do have cd drives that are slot-loaders may lose the bootable business card in the slot and get annoyed.
That said, the bootable business card image is the smallest download available to install debian without having to mess with a netboot configuration. You can still use the mini iso with a normal cd, or via virtual drive, etc. I used to always keep an 80mm (185MB) installer CD-R in my bag back before it made more sense to just use a thumb drive.
It turns out I just couldn't remember where they were, and they do still exist:
