  • Patent number: 6918536
    Abstract: A monitoring apparatus for an automated teller machine (ATM), a call center, and a monitoring system. Even when a call center installed in an area is not in its service hours, the system can cope with an inquiry from a user in real time and realize a smooth 24-hour service. The system includes the ATM, the call center for monitoring and controlling the state of the automated teller machine at a remote place, and the monitoring apparatus for sequentially registering run information received from the ATM, service information and operator information received from various locations in the world. When receiving an inquiry from a user, the monitoring apparatus refers to information previously held in a storage within the monitoring apparatus, transmits the inquiry to the call center in service, and also transmits machine information and operation information of the monitoring apparatus from the monitoring apparatus to the call center.

  • Patent number: 6899269
    Abstract: Magnetic stripe documents are identified and authenticated on the basis of repeatable magnetic characteristics of a stripe recorded with digital data and waveform characteristics of the sensed digital data. Stripes are sensed to provide an analog signal, only the portion storing leading zeros being used. Cyclically, the leading-zero portion is sampled and digitized to provide a target number of samples using a frequency locked loop. The target number of samples is then reduced by a selection process that attains a predetermined number of digital samples from central locations in magnetized portions of the record specifically, spaces between data transitions. Selected groups, each of a predetermined number of digital samples, are then combined to provide magnetic characteristic data. Such data is then combined with waveform data (range) to provide an identification word. Documents are verified by correlating reference and sensed identification words.

  • Patent number: 6883707
    Abstract: The present invention recognizes denomination and transporting direction of each bill to be deposited when the bill is deposited, selectively drives two light sources with different emission colors based on the recognized information on the denomination and direction of the bill, and scans and reads the portion where the serial number of the bill being transported is printed by means of an image sensor, so that the serial number of this bill is read while selectively changing the emission color of the light source according to the denomination of the bill. Even if the character color or background color of the serial number differs depending on the denomination, the serial number can be accurately recognized without providing many light sources with different emission colors.

  • Patent number: 6880751
    Abstract: A method for issuing coupons through an automatic transaction apparatus, which permits consumers to enjoy discounts or other promotional services more widely and conveniently. Coupon descriptors containing various coupon information are stored in association with output medium identifiers. Each output medium identifier specifies at least one of a plurality of recording media (e.g., IC card, paper, portable information equipment) that can be used to store coupon information. When issuing a coupon to a user, the automatic transaction apparatus identifies which recording medium to use as an output medium for the requested coupon, by consulting a relevant output medium identifier. If there are two or more selectable media, the user is prompted to make a selection. The apparatus then outputs the coupon information to the identified or selected recording medium, thereby issuing a coupon to the user.

  • Patent number: 6879740
    Abstract: A device for optical space switching in optical networks. The optical device comprises a broad area optical waveguide section having a number of electrodes extending over at least a portion of the length of the broad area optical waveguide section. The application of an electrical signal to an electrode causes a local change in effective refractive index of the broad area optical waveguide section, thereby causing light preferentially to propagate along a predetermined path in dependence on the configuration of the electrode. In particular the broad area waveguide device is implemented in indium phosphide (InP). Also described is a method for waveguiding in the optical device.

  • Patent number: 6851607
    Abstract: A secure system and method for the transfer of value units between a plurality of gambling cards (CJ) and a plurality of gambling machines (200, 300). Each machine has a transcriber (210, 310) to debit value units of the gambling cards. The machines are connected via a secure network (123) to a central processing unit (1). Each gambling card (CJ1) stores data (S, Op1, Op2, Opx, Id, S) unique to the card and the use of that card in gambling. The central processing unit (1, BD) stores the same data as what is in the cards. The cards' and the CPU's data are maintained in parallel as the gambling progresses, and may include data from previous sessions. A monitor (BD) checks that the CPU (1, BD) data and the card (CJ1) data correspond. Thus the integrity of this smart card gambling is enhanced.
