I don’t know if they do, but I’ve used a service before that provides similar functionality, a “temporary proxy credit card”, which also permits one to not even provide one’s real name and address to a vendor.

But it’s more work to set one up than it is to do a PayPal transaction. Like, I could do it if a vendor doesn’t permit for PayPal payments and I really really want what the vendor is selling, but PayPal does the big “the vendor doesn’t get your credentials” securiry fix and avoids creating extra hurdles for a purchaser to jump through.
