Abstract
An improved touch screen encryption device and method is disclosed. The user selects information from prompts displayed on a touch screen. The improved device determines the input information based upon the location of the touch. The device encrypts the information--for example, the user's personal identification number--and sends the encrypted information to a remote processor. The device and method may be used by a financial institution (such as a bank), a postal services institution or wherever sensitive information is input through a touch screen.
