  • Patent number: 10394186
    Abstract: A powder container is for use with an image forming apparatus, and the image forming apparatus includes a driving protrusion that is rotatable and that protrudes toward an upstream side in an insertion direction in which the powder container is inserted. The powder container includes a container body to store powder, a cap attached to the container body, and a transmitted structure provided on the cap to contact the driving protrusion. The transmitted structure extends outward from an outer circumference of the powder container. The cap is rotatable relative to the container body in a predetermined angular range. The rotation of the cap relative to the container body is restricted so that the container body rotates along with the rotation of the cap when the rotation of the cap exceeds the predetermined angular range.

  • Patent number: 8094890
    Abstract: A biometric authentication apparatus for identifying a subject person by using biometric information of a user has memories and a processing unit for performing biometric authentication. The memories and store a remaining trial number whose value is reduced each time biometric authentication fails. The processing unit generates a lower limit value smaller than the remaining trial number at the start of biometric authentication, performs biometric authentication until the reduced remaining trial number becomes equal to or smaller than the lower limit value, and generate alarm data for issuing alarm to the user when the reduced trial number becomes equal to or smaller than the lower limit value.

  • Patent number: 7737824
    Abstract: A hierarchical structure is established among a plurality of RFID tags, such that ID numbers can be read only from RFID tags which belong to a particular layer. RFID tag can control whether permission should be given to read its ID number therefrom to protect the ID number. Data held in the RFID tag can be read from the outside. RFID tag comprises a memory circuit having a function of holding data, and a logic circuit having a function of processing a control command received from outside. Memory circuit stores an own ID number for identifying the RFID tag itself, and a parent ID number for identifying a second RFID tag. When RFID tag receives an ID number read command which contains first data as a parameter from outside, the logic circuit outputs the own ID number to outside only when the first data matches the parent ID number.

  • Patent number: 7628323
    Abstract: In a settlement transaction system or settlement transaction method using the system, the system includes a content providing server conducting a digital broadcast, for example, for a CS broadcast, a BS broadcast, a CATV, or a broadcast using ground waves; a settlement server to execute settlement transaction or settlement transaction, an order placement managing server to execute order placement processing, and an order managing server which receives an order of a request from a user to purchase articles and which sends an associated indication to the settlement server and the order placement managing server according to information of the order. The user operates a terminal in which an IC card communication application to communicate with an IC card is only installed. It then becomes possible to reduce a load imposed onto the system in association with a change to an existing digital broadcast system.

  • Publication number: 20090287606
    Abstract: An electronic money transferring method that enables the payment of electronic money through an electronic money transferring system with reliability. An external information processor is operated to enter the product number of a desired product, and then a host apparatus sends information about electronic money information indicating an amount of money necessary for purchasing the product, etc. to a control unit. The data processing unit reads electronic money information indicating the amount of money from an IC card. The electronic money information is transferred to the host apparatus.

  • Publication number: 20080180212
    Abstract: A settlement terminal including a password input unit for inputting the password of a user and a biometrics information acquisition unit for acquiring the biometrics information of the user based on a predetermined biometrics authentication method is disclosed. Before person identification of the user, the settlement terminal receives a person identification method list containing available person identification methods and the person identification method priority order indicating the priority order of the person identification method from the IC card. In accordance with the person identification method list and the priority order of the person identification method, the settlement terminal thus determines whether to conduct the password verification using a password input unit or the biometrics authentication using a biometrics information acquisition unit.

  • Patent number: 7356645
    Abstract: In a portable terminal having an IC card, the outstanding SF value, the commuter pass information and the conditions for the corresponding operation to charge the SF value or renew the validity period of the commuter pass are stored in the IC card. The outstanding SF value and the validity period of the commuter pass are checked at a predetermined timing. In the case where the outstanding SF value and the validity period satisfy the conditions for the corresponding operation (in the case where the outstanding SF value is reduced to less than a predetermined amount, for example), the set corresponding operation is performed. Thus, a predetermined amount is charged against the outstanding SF value, or the oncoming expiry of the validity period of the commuter pass is notified. The conditions for the corresponding operation can be set and changed appropriately at the portable terminal.
