Abstract
An electronic cash register includes a clerk identifying system, wherein the clerk who handles the electronic cash register must be first registered before initiating the actual registration operation. An operation ability determination circuit is provided for determining whether specific operations can be performed by a specific clerk. When the system is preset not to perform, for example, the defrayment operation when the clerk "A" handles the electronic cash register, the defrayment key is disabled when the clerk "A" handles the electronic cash register.
