摘要:
A prepaid card management system includes a memory and a determining unit. The memory causes a card to store a fixed card number together with value information and stores the value information and the card number in correspondence with the value information when a service is finished. The determining unit stops a service when value information read out from the card upon starting of a service is larger than the value information read out from the memory in correspondence with the card number.

A portable prepaid card includes a substrate (14) on which a photoconductive layer (13), a liquid crystal layer (12), and a transparent electrode plate (11) are built up in this order. When an optical image is radiated on the photoconductive layer through the liquid crystal layer, the exposed regions and the unexposed regions of the photoconductive layer have different volume resistances. In this state, if a predetermined voltage is applied from the outside between the electrode plate and the photoconductive layer, a visible image corresponding to the radiated optical image is fixed in the liquid crystal layer.

An obliteration device comprising, in combination, a magnetic obliteration head (TM) and a mechanical means such as a toothed wheel (R) which is pushed by an actuator (EM), controlled by a microprocessor (n, P), into contact engagement with the magnetic support of the card to fully or partially etch and/or score the portion of support to be obliterated.

A card issuance apparatus (10) has an input means (11) for inputting data required for issuing a card (1), a memory means (17) for storing the data, a recording means (16) for recording the data in a recording section (2, 4) on the card (1), a comparing means for comparing the data stored on the card with the data stored in the memory means (17), and a cancellation means for cancelling the data stored in the memory means (17).
摘要:
A previous ticket is read by a previous ticket reader unit (11), and the contents of read information are displayed on a CRT display unit (9), and are modified by departure/destination station information input sections (1, 5) and a condition input section (3). Thereupon, a new pass is issued by a printer/encoder unit (27) in accordance with the modified information.

In a pay phone system, a plurality of pay phone apparatuses (40) and a remote central computer (54) are included. The pay phone apparatuses (40) communicate with the central computer (54) through telephone. lines and further via a telephone central exchange (52). The pay phone apparatuses (40) are operated by means of magnetic cards (55, 56 or 57) or optionally by means of coins. Each card (55, 56 or 57) includes information or data readable from the card and identifying the card and further representing an amount corresponding to an allowable telephone call duration. The pay phone system is operated in the following manner: The card (55, 56 or 57) is received in a card receiving slot (421 in the apparatus (40) and the data of the card are read from the card and stored in a first storage means of the pay phone apparatus. The first storage means of the pay phone apparatus is addressable from the remote central computer (54) for transferring data stored in the first storage means to the remote central computer. In a second storage means of the pay phone apparatus, data transferred from the remote central computer (54 are stored. In a comparator means of the pay phone apparatus, the data read from the card and stored in the first storage means are compared to the data stored in the second storage means. By the comparison, the card is identified as a legal card or as an illegal card identified by the data of the second storage means. In case the card is identified as an illegal card, the card is rejected from the pay phone apparatus. In case the card is identified as a legal card. a telephone call is permitted. In a debiting means, an amount corresponding to the duration of the telephone call is determined and in a subtraction means of the pay phone apparatus, the amount is subtracted from the data stored in the first storage means representing the amount corresponding to an allowable telephone call duration, and a reduced amount is generated and stored in the first storage means. When the amount determined by the debiting means exceeds the amount corresponding to the allowable telephone duration, the telephone call is interrupted. At the end of the telephone call, the data stored in the first storage means are written in the card by means of a writing means of the pay phone apparatus and identifies the card and further represents the reduced amount corresponding to an allow able telephone call duration. Periodically, the remote central computer (54) addresses the first storage means of the individual pay phone apparatuses and transfers the data stored therein to the remote central computer for processing therein. On the basis of the data transferred from the first storage means of the individual pay phone apparatuses, the remote central computer updates the data of the second storage means of the individual pay phone apparatus.
摘要:
Afin d'empecher toute falsification d'une carte de credit ou d'identite (60), on applique, sur une zone determinee, une marque de couleur definissant la longueur d'un trajet ou delimitant un trajet. La longueur du trajet est convertie en donnees de marquage numeriques et enregistree sur une piste d'enregistrement (65). Lors de la verification de l'authenticite de la carte (60), la longueur du trajet est de nouveau etablie et convertie en donnees de marquage numeriques qui doivent coincider avec les donnees enregistrees sur la piste d'enregistrement (65).
