Patent number: 9016568Abstract: A reader device performs control to cause rates of transmission at the time of transmitting an authentication command to an IC chip included in a passport to be different from each other. Then, when the rates of transmission are caused to be different from each other, each of required times T1 and T2 required after transmitting the authentication command to the IC chip until receiving a response to the authentication command from the IC chip is measured. An operation time Tc required for execution of the authentication command in the IC chip is calculated on the basis of the required times T1 and T2 measured as described above, and, further, genuine/counterfeit judgment of the IC chip (genuine/counterfeit judgment of the passport is performed on the basis of the calculated operation time Tc.Type: GrantFiled: February 22, 2013Date of Patent: April 28, 2015Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Satoru Wakao, Junichi Sakaki
