Most credit card issuers will happily give you extra cards, so your
friends can spend your money.  In whatever name you want.  If you need
to show ID, this can become, umm, complicated.
This goes along with paypal's "send a friend a debit card" feature (I saw this two years ago, I don't know if this is still present), but this essentially allowed a user to add any name to the debit visa card (treated in most places like a credit card) which in some cases actually allowed online hijacking of domain names (depending on registrar) because the name was the same on the visa card used.
