Remembering PIN

Several minutes ago my wife sent me a message. She needed to withdraw some money using our ATM card and apparently she forgot the PIN Number. So she asked me for the number. Unfortunately I also forgot, because both of us had not used that ATM card for quite some time. Of course we could go to the bank to get the PIN Number reset. But it would take time, and it was getting late in the afternoon that the bank was already closing, while she needed the money fast.

Fortunately, I seemed to remember keeping note of the number somewhere on my PDA. So I did a search on files on the device, and there it was: I did keep the information on my PDA, in an encrypted file. What followed are just simple processes of transferring the file into my workstation, running the decryption software on the file, reading the PIN and sending the info back to my wife. The next message I received was that she had successfully withdrawn the money :-)
