Conventionally, the owner has been identified using a password or the like when accessing information or performing a predetermined processing operation. However, when a password is used, there is always a risk that the password itself will be stolen. Therefore, there are cases where an individual is identified using a method other than the password, for example, personal biological information.
In personal ecological information, for example, it may be possible to use pattern identification such as finger veins, fingerprints, voice prints, and irises of eyes. Among them, finger vein recognition, which is considered to be practical, has attracted attention.

As a method for identifying a finger vein pattern, for example, there is an automatic transaction apparatus disclosed in Japanese Patent Application No. 2007-25840, which includes a card unit for reading a card in which finger vein information is registered, and a display unit having a display screen. And a biometric information reading unit that reads finger vein information as a separate body, and a control unit that comprehensively controls them.
The control unit controls to display the guidance for holding the finger of finger vein information registered on the card on the display screen, and controls to display the guidance for holding the finger of finger vein information registered on the card on the display screen. Then, it is determined whether or not there is a plurality of finger vein information registered in the card, and when there are a plurality of pieces, control is performed so that guidance for holding each finger is displayed on the display screen.
