This is the only reason I still have a Citibank card and so far, it hasn't been cracked. I've used it nearly 10 years.
I can buy fearlessly from anyone, knowing 2 things about this number: It can be used just once It expires in 1 month http://en.wikipedia.org/wiki/Controlled_payment_number Alas, the only one who has the best implementation is Citibank. The amexco version ceased operation in 2004-5, I used to use it regularly. The Discover card version generates numbers with 1 year expiration and is not user adjustable. If the numbers cannot be used, it will be rejected. Paypal for example, will not allow such numbers to be used as a source for payment.

In the rare event I use my credit card, Citibank supplies a program call called virtual account numbers. It creates for you a one time only credit card number. This guarantees no one can grab your number and use it. From what I've seen its also offered by other banks under different names. Good luck Rix ------------------------------ _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
