Cash is most anonymous. However, some credit card companies offer temporary credit card numbers where you can set a limit and expiration date. Takes a couple mintues to set up. Statistics show that identity theft and fraud is far more likely (on the order of 90%, if memory serves) to occur by non-electronic means; most likely it will be someone you know or have had direct contact with (ie. a disgruntled waitress you handed your card to after dinner).gunsmoker said:These are Great. I want some. But I'm not sure that I want to give my name, address, and credit card information to some organization just to buy some of these. Due to marketing / telemarketing, junk mail and spam, not to mention credit fraud concerns, there is a built-in "transaction cost" every time you do business with somebody in a transaction ther than anonymously in cash.
