Abstract

Thieves have often targeted automated teller machine (ATM) users by stealing the user's personal identification number (PIN). One way is to steal the PIN by observing the user from a distance using a pair of binoculars to capture the keying in of the PIN and later stealing the users ATM card. To prevent thieves from stealing PIN numbers, a method of scrambling the "keypad" and making the "keypad" virtually unreadable from a distance is a solution. By scrambling the keypad layout a thief observing from a distance would not be able to unscramble the keypad nor would he be able to determine which numbers were entered as he could no longer be able to view the keypad.
