INTEGRATED CIRCUIT MEDAL

摘要

PURPOSE: An integrated circuit medal is provided to substitute for a subway pass and other traffic cards, thus solving various problems caused by the use of paper as well as increasing the utility of resources. CONSTITUTION: The integrated circuit medal is constructed by inserting non contact type radio frequency integrated circuit(3) or coil, which is able to perform more complex functions than existing subway pass or other traffic cards, inside compressed coins(1,2), and attaching epoxy coating. The coil differently recognizes pulse codes according to a degree of winding thereof, thereby recognizing and detecting signals as different various kinds.
