The Greendot company had a card called "WebSecrets" that you could load one-time with whatever about up to I think 1,000. you wouuld then anonymously register whatever name/addy etc you wanted online and it was good everywhere.
Now, the greendot cards have to be registered with your actual information before you use them. iow, they verify SS# name,addy,etc
next best thing out there now for the casual anonymity seeker is the "Vanilla Visa" card. pre-paid fixed denominations of 25, 50, 75, 100 that I know of. havent seen higher.
the problem is theres no name/adress associated with them so they fail AVS verification at some online sites. Other sites that dont do AVS verification (and only check for avaialable funds) you just use any name/addy. dont know which process EF uses.
