Abstract

A monitoring method includes acquiring tag identification information unique to a radio frequency identification tag carried by a person, and reader identification information about a tag reader that detects the radio frequency identification tag. Next, attribute information about the person is acquired based on the tag identification information, and area information about a detection area of the tag reader is acquired based on the reader identification information. Finally, it is determined whether the person carrying the radio frequency identification tag having the attribute information acquired is allowed to enter into the detection area based on the area information.

acquiring a set of the tag identification information and the reader identification information corresponding to a predetermined time based on the positional history,

wherein the acquiring of the tag identification information and the reader identification information is performed at the acquiring based on the set of the tag identification information and the reader identification information.

4. The monitoring method according to claim 1, further comprising outputting a warning when it is determined that the person carrying the radio frequency identification tag is not allowed to enter the predetermined area.

5. The monitoring method according to claim 4, wherein the outputting includes displaying the warning.

6. The monitoring method according to claim 4, wherein the outputting includes transmitting the warning to the radio frequency identification tag via the tag reader.

7. The monitoring method according to claim 1, further comprising controlling a lock mechanism corresponding to a door so as to shut the door based on information about a position of the door and the area information, when it is determined that the person carrying the radio frequency identification tag is not allowed to enter the predetermined area.

8. The monitoring method according to claim 1, further comprising:

controlling a camera that monitors the predetermined area, based on information about a position of the camera and the area information, when it is determined that the person carrying the radio frequency identification tag is not allowed to enter the predetermined area; and

recording a video with the camera.

9. A monitoring method comprising:

acquiring tag identification information that is unique to a radio frequency identification tag carried by a person, and reader identification information that is unique to a tag reader capable of detecting the radio frequency identification tag in a predetermined area;

recording positional history that indicates a position of the radio frequency identification tag at a certain time based on timing at which the tag identification information and the reader identification information are acquired;

recording a video of the predetermined area and time at which the video is recorded;

calculating the number of tag identification information detected by a predetermined tag reader based on the positional history;

calculating the number of persons in the predetermined area based on the video; and

determining whether the number of the tag identification information is equal to the number of persons.

10. The monitoring method according to claim 9, further comprising outputting a warning when it is determined that the number of the tag identification information is not equal to the number of persons.

11. The monitoring method according to claim 10, wherein the outputting includes displaying the warning.

12. A monitoring method comprising:

acquiring tag identification information that is unique to a radio frequency identification tag carried by a person, and reader identification information that is unique to a tag reader capable of detecting the radio frequency identification tag in a predetermined area;
