ABSTRACT:
An identification apparatus comprising an array of retractable conductive pins on a base component placed onto a primary device and in communication therewith. A set of shaped identifiers have a plurality of holes through which respective pins on the array of retractable pins pass, each identifier being uniquely configured with at least one distinct location containing a conductive plug or ‘cap’ fitted therein which blocks the passage therethrough of that particular pin thereby forcing said pin to retract into the base component to block further use of that pin by subsequently placed identifiers. Each retractable pin is in individual communication with the primary device such that, once one or more identifiers have been placed onto the pin array, the primary device can thereafter identify the placed identifiers so as to subsequently perform certain functions or other desired operations based on the type, configuration, and/or number of identifiers placed thereon.
