Abstract
A system and method are provided for validating a signature on a touchscreen using a smart stylus. Software residing on a touchscreen device disables touch input from sources other than the stylus. In one embodiment, the stylus wirelessly transmits a stylus identifier to the touchscreen device to identify the stylus to the device. The stylus may also have a stylus tip that produces an encoded voltage pulse sequence that is used to identify the stylus to the device. A stylus ID is associated with an encoded voltage pulse. The touchscreen device can look up the stylus ID in a database, determine the encoded voltage pulse associated with the stylus ID, and determine that a voltage pulse transmitted by the stylus tip is the pulse associated with the stylus ID, thus validating the source of data input on the touchscreen.
