How does the 6 digit randomly generated security code from (disconnected)Verisign Identity Protection card helps in verification/validation of any user?
Why one cannot enter any random 6 digit value instead of generating that value from VIP card/device?
Is there any fixed pattern of getting those values from that VIP device/card so that the server can verify that number?

I think this should go to [security.se] instead. – JJJ Jul 04 '14 at 09:53
