Ironvest.com (nee blur.com, nee abine.com) also provides a "masked card" service (which can be independently useful, as it can have a bogus name and address, useful if you don't want someone harvesting that). Used to be with cash payments that vendors couldn't build that kind of database. That being said, they charge an annual fee for their service, and your bank may provide free temporary numbers. And not every vendor will accept their masked cards (or those prepaid cards from stores), I assume because those vendors want to link them to your identity. There are legit reasons for vendors to want to do that, like to reduce fraud, but if you don't want your name in vendor databases, it's a way to avoid it.
