It's nice for consumers to know the rules. For instance, if I screw up my PIN at an ATM, I will retry once, but not twice. Because I know that if I screw up in my third attempt, I won't have a card for a while. It's amazing how unsure I am with a PIN after I make a mistake. My office has coded entry - but the third floor has a different shaped keyboard. The numbers are worn out of the main keyboard but I don't really enter my entry PIN by number, but by motor memory - which doesn't work when the keyboard is arranged differently. But hackers also like knowing the rules. They can try twice per day to hack a PIN just the same way as consumers do. Passwords are a technology that needs to be replace. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
