Description

  The present invention relates to an entrance / exit management device for managing entrance / exit of a person at an entrance / exit door of a building or a building.

In an entry / exit management apparatus using an authentication portable medium such as an IC card, the authentication portable medium may be updated at regular intervals in order to improve security.
One personal number, which is information for identifying an individual, is given to one person, and one unique number, which is information for identifying a portable medium for authentication, is assigned to the one personal number. If it is, the personal information table of the access control apparatus needs to be updated simultaneously with the update of the authentication portable medium. In this case, if the number of authentication portable media increases and the scale of the personal information table increases accordingly, it becomes difficult to simultaneously update the authentication portable media and the personal information table of the access control device. There was an operational problem.
Therefore, one person prepares the above-mentioned authentication portable medium for before-updating and after-updating, and the entry / exit management device has a separate medium for both the before-updating and after-updating authentication portable media. If a unique number is assigned and stored, authentication can be performed on both the pre-updating and post-updating authentication portable media, so the personal information table of the access control device is updated first, and then authentication is performed with a margin. It is possible to update the portable media.
However, in this case, two personal numbers are assigned to the personal information table of the access control apparatus, and a unique number is assigned to each personal number. Therefore, it was necessary to increase the storage capacity of the access control device.

Therefore, as a conventional entry / exit management device, one individual number is given to each person, and a unique number before and after updating is assigned to the individual number. Alternatively, an entry / exit management apparatus is known in which either one of the unique numbers after the update is stored and both the unique number before the update and the unique number after the update are stored in the authentication portable medium (for example, , See Patent Document 1).
In this case, since the entry / exit management device can authenticate even if the personal information table is not updated, the personal information table of the entry / exit management device with a margin after the authentication portable medium is updated first. There is an advantage that update work can be performed.
