Output device capable of preventing the leakage of confidential information

An information processing system comprising a portable terminal device and an output device, each of the portable terminal device and the output device including plural communication units having different communication areas and configured to establish communication in order to transmit data from the portable terminal device to the output device via contactless communication;

• wherein the output device includes:
• a determination unit configured to determine whether or not the portable terminal device is within a predetermined communication area based on the identified communication unit;
• a granting unit configured to grant output of the received data from the output device when it is determined that the portable terminal device is within the predetermined communication area;
• and
• an output unit configured to output the data whose output is granted by the granting unit, wherein
• the determination unit includes an identification unit, a first determination unit and a second determination unit different from the first determination unit,
• the identification unit is configured to identify one, from among the plural communication units, which receives the data from the portable terminal device,
• the first determination unit is configured to determine, according to the communication unit identified by the identification unit, whether it is necessary to determine a distance to the portable terminal device based on a radio wave intensity, and
• the second determination unit is configured to determine, in a case where the identification unit identifies a first communication unit and the first determination unit determines that it is not necessary to determine the distance to the portable terminal device based on the radio wave intensity, that the portable terminal device is within the predetermined communication area, and determine, in a case where the identification unit identifies a second communication unit and the first determination unit determines that it is necessary to determine the distance to the portable terminal device based on the radio wave intensity, whether the portable terminal device is within the predetermined communication area according to the distance determined based on the radio wave intensity.

A method of outputting data via an output device with which a portable terminal device is configured to communicate via contactless communication, each of the output device and the portable terminal device including plural communication units having different communication areas, the method comprising the steps of:

• establishing communication between the output device and the portable terminal device;
• receiving data from the portable terminal device via contactless communication;
• identifying one of the plural communication units of the output device that receives the data from the portable terminal device;
• determining, using a determination unit, whether the portable terminal device is within a predetermined communication area based on the identified communication unit of the output device;
• granting output of the received data from the output device when it is determined that the portable terminal device is within the predetermined communication area;
• and
• outputting the data whose output is granted in the granting step, wherein
• the determination unit includes an identification unit, a first determination unit and a second determination unit different from the first determination unit,
• the identification unit is configured to identify one, from among the plural communication units, which receives the data from the portable terminal device,
• the first determination unit is configured to determine, according to the communication unit identified by the identification unit, whether it is necessary to determine a distance to the portable terminal device based on a radio wave intensity, and
• the second determination unit is configured to determine, in a case where the identification unit identifies a first communication unit and the first determination unit determines that it is not necessary to determine the distance to the portable terminal device based on the radio wave intensity, that the portable terminal device is within the predetermined communication area, and determine, in a case where the identification unit identifies a second communication unit and the first determination unit determines that it is necessary to determine the distance to the portable terminal device based on the radio wave intensity, whether the portable terminal device is within the predetermined communication area according to the distance determined based on the radio wave intensity.
