INFORMATION RECORDING MEDIUM, LABEL WITH THE INFORMATION RECORDING MEDIUM, TRANSFER SHEET WITH THE INFORMATION RECORDING MEDIUM, ARTICLE WITH THE INFORMATION RECORDING MEDIUM, AND GENUINENESS DECIDING METHOD

摘要

PPROBLEM TO BE SOLVED: To provide one of an information recording medium which has higher forgery prevention effect than a conventional machine-readable diffraction grating pattern, a label with the information recording medium, a transfer sheet with the information recording medium, an article with the information recording medium, and a genuineness deciding method. PSOLUTION: The information recording medium (1) has a contactless information record carrier (2) having an integrated circuit chip (21) and an antenna (22) for contactless communication and a machine-readable optical information recording part (3) at least on a base (11) and is characterized in that information related to unique information recorded on the contactless information recording carrier (2) is recorded in the machine-readable optical information recording part (3).
