Abstract
A method of processing a transaction comprising the steps of generating a position signal indicative of position of a touching of a touch screen having a transparent reference surface, displaying an image of the touching of the screen responsive to the position signal, and changing the image as a function of the difference between the position signal and a predetermined position value.
Claims27
A transaction terminal comprising:
- a touch screen having a transparent reference surface for generating a position signal indicative of position of a touching of the screen;
- a display that is under the transparent reference surface that is responsive to an input signal which creates a image on the display;
- and,
- a controller for capturing position signals and generating the input signal, the input signal being a function of the captured position signals and a predetermined position value signal that is indicative of a predetermined position where a person is expected to sign on the display and generating an offset correction value to cause a displayed signature to migrate closer to the predetermined position,
- wherein the image changes position on the display during the capture of the position signals.

- displaying an image of the touching of the screen responsive to a function of the position signal;
- and,
- capturing position signals and generating an input signal, the input signal being a function of the captured position signals and a position value signal indicative of a predetermined position where a person is expected to sign on the display and generating an offset correction value to cause a displayed signature to migrate closer to the predetermined position,
- wherein the image changes position on the display during the capture of the position signals.

A method of processing a transaction comprising the steps of:
- activating a display to present an image on the display to assist a person to sign the display;
- displaying a virtual signature placement element at a predetermined position where a person is expected to sign the display;
- manually moving a stylus in a cursive manner corresponding to the writing of the person's signature;
- sensing a series of positions of the stylus and generating a series of corresponding position coordinates;
- creating a digital record of the signature by storing the coordinates in memory;
- causing the display to display an image of the signature concomitantly with movement of the stylus;
- changing the position of the image of the signature as a function of the difference between the series of corresponding position coordinates and the predetermined position value during the capture of the signature.
