摘要： An electronic component uses a secret key cryptographic algorithm that employs several successive computing cycles to supply final output data from initial input data applied at the first cycle. A first random value is applied to a computation conducted for each cycle, to obtain unpredictable output data. A second random value as also applied to the initial input data that is used for the input of the first cycle.

摘要： The present invention relates to a process for producing an opaque, transparent or translucent transaction card having multiple features, such as a holographic foil, integrated circuit chip, silver magnetic stripe with text on the magnetic stripe, opacity gradient, an invisible optically recognizable compound, a translucent signature field such that the signature on back of the card is visible from the front of the card and an active thru date on the front of the card. The invisible optically recognizable compound is an infrared ink and/or film, which can be detected by a sensor found in an ATM or card assembly line.

摘要： Playing cards that include a machine-readable bar code in the form of a number of mutually parallel and juxtaposed bars, wherein the code is adapted to be read by light sensitive detectors. Each playing card includes at least one six-position binary code in which a bar is either present or absent at each of the six positions. The code includes a reference code in the form of an additional bar in at least one further position adjacent to the six-position binary code. The reference code is positioned for detection by a light sensitive detector. The binary code is intended to be read by means of the light sensitive detectors when the existence of the reference code is detected.

摘要： In a PC card to be connected to a personal computer, two kinds of operational modes which are different in data bus width from each other can be changed over selectively. Either the CardBus mode with a data bus width of 32 bits or the 16-bit mode is selectable by a selector switch provided in a side face. The PC card 1 is operated in the 16-bit mode for use with a 16-bit-compatible personal computer, and operated in the 32-bit mode for use with a 32-bit-compatible personal computer. Thus, one PC card is useable with various personal computers.

摘要： In a memory card, identification numbers identifying the memory card are permanently stored in fuse blown registers formed in each of two redrive chips, which function to read out data from memory chips of the memory card and store data in the memory chips of the memory card. Each identification number separately provides a unique identification of the memory card. The identification numbers are each stored with an error correction code by which single bit errors en the identification numbers can be corrected and the occurrence of multiple bit errors in the identification numbers can be detected. Both identification numbers, if valid, are used to identify the memory card and both of the identification numbers, if valid, are stored in association with memory quality events occurring on the memory card, so as to provide a redundant identification of the memory card on which the memory quality events occurred.

摘要： The present invention provides a card type recording medium such as an IC card, which contains storage units to store data and an access control unit to control an access to the data by an access subject. The access control unit is designed to include an access subject identification information generating unit to generate an access subject identification information for identifying the access subject, an access authority information read-in unit to read in access authority information set in correspondence with the data that the access subject requests to access, and a control unit to obtain an access authority from the access subject identification information and the access authority information, and to control an access to the data by the access subject on the basis of the access authority obtained. Thereby, the card type recording medium intends to simplify the setting and modifying work of an access authority, and to reliably perform the management and operation of a security system.

摘要： A memory card is disclosed which has a card body (2) having a concavity (9) formed at the forward end thereof in the inserting direction and in which terminals (5) are disposed and projections (10) are formed between the terminals (5) to prevent the terminals (5) from being touched or accessed from outside. A receptacle for the memory card is also disclosed. The memory card has a simple structure designed to positively protect the terminals and easily let out dust or the like from inside, thereby permitting to assure a positive connection with the receptacle.

摘要： A financial transaction card is transparent or translucent to human viewing yet detectable by automated card processing equipment. The card includes a substantially planar material sheet having upper and lower surfaces bounded by a continuous peripheral edge. The material sheet has one or more areas that are at least minimally transparent or translucent with respect to human-visible light. A filter associated with at least one of the areas provides sufficient opacity to light that is detectable by sensors in the automated card processing equipment to render the card detectable by the equipment.
