Abstract
An electronic seal stamp and an electronic sheet are used. The electronic seal stamp has a stamp surface, and has a storing function and output function for electronic information. The electronic sheet is of a sheet shape, has a surface capable of being impressed, and has a storing function and input function for electronic information. When the electronic seal stamp is impressed on the electronic sheet, a seal image on the stamp surface of the electronic seal stamp is transferred to the surface of the electronic sheet. At the same time, the electronic information stored in the storing function of the electronic seal stamp is transferred to the storing function of the electronic sheet, through the output function of the electronic seal stamp and the input function of the electronic sheet. Thus, an electronic seal stamp system, in which both impression of the stamp surface and electronic sealing are possible, is realized.
