Abstract
A transaction terminal includes a touch-screen display and various peripherals in electronic communication with and under the control of a processing unit. A PIN entry area is generated by the processing unit that includes a video keypad. The video keypad, in conjunction with the touch-screen, allows entry of a PIN, ID, or the like. A shield or barrier is provided adjacent at least a portion of the video keypad of the PIN entry area that aids in the prevention of eavesdropping by a third party during PIN entry. In one form, at least one shield extends over and above the video keypad for extra privacy. In another form, walls are situated adjacent sides of the video keypad. Preferably, the PIN entry area is also labeled as such on the display independent of the display region in order to indicate the only proper place for PIN entry to the user. This aids in preventing Trojan horse applications that can show a false PIN entry area on another part of the display region in order to fraudulently obtain a user's PIN.
