Abstract A video display terminal is disclosed which may simultaneously display graphics and alphanumerics on the same screen and in superimposed relationship. The terminal may take the form of an intelligent, processor driven terminal having a conventional bus architecture. Data may be inputted by way of a keyboard or other peripheral, such as a host computer, and stored in a read/write memory, such as a random access memory (RAM). Data stored in the RAM may be outputted and displayed on the terminal display screen. In addition, graphics picked up by a closed circuit TV camera may be dynamically displayed on the terminal screen in real time. The graphics information may then be frozen and transmitted to a remote location, such as a host computer, for long term storage. The static graphics thus recorded can be called up and redisplayed on command at the same or a different video display terminal communicating with that host computer. Alphanumeric information associated with that graphic image may also be entered at the terminal and recorded at the host computer. Both the graphics and alphanumerics may then be simultaneously displayed in superimposed relationship, if needed, on a video display terminal. One particular application of this system is in signature verification such as might be used by a teller at a branch bank or by a sales clerk in a department store for validating signatures.
