Abstract
A hand stamp with a use count mechanism and security elements for preventing unauthorized use. The use count mechanism includes a magnet mounted on an inner shell for relative movement with a stamp image platen carried by an outer shell, a magnetic field sensor carried by the outer shell for sensing movement between the magnet and the outer shell when the platen is moved to a stamping position, and an MCU for converting sensor signals to signals for a display. The security elements include print sensors mounted on the outer shell for sensing the finger prints of a user, with the MCU configured to convert these signals for transmission via a Bluetooth module to a smart phone containing finger print signals of an authorized user. If the fingerprint signals match, the smart phone sends an authorization signal to the MCU, which responds by unlocking the hand stamp.
