摘要:
A security device for use in a card charging system where a service or product providing facility issues services or products by the use of credit from a card. The security device comprises signal transmission means for delivering signals to a purchasing facility to enable a user to acquire a service or product dependent on the credit debited from a card, a record keeping subsystem to certify the credit debited from the card and to identify which account is to receive the debited credit and signal processing and output means for generating signals indicating a successful transaction. The signals may be encoded by use of encryption techniques. A separable security subsystem is provided to ensure a record of transactions is available if power fails on the main security device.

In a card charging system, especially for public transport services, a host ticket facility is operable by both credit cards usable at a card read/write device and concessionary payment cards usable at a contactless card reader, and a security and transaction device located between the card readers and the host facility stores in separate storage devices full fares and concessionary fares which the host facility is able to calculate. A card charging system, especially but not exclusively for payment of public transport fares is described, having one or more card readers and a security and transaction device connected between the card reader(s) and a host facility and for transmitting information back to a clearing centre, wherein the security and transaction device includes a number of non-volatile storage devices for error counting and transmitting related performance data back to the clearing centre. A card charging system can include a security and transaction (TSM) device located between a smart card reader, such as a contactless card reader, and a host facility to enable a purchase to be made in return for a credit debited from the card, wherein the TSM device stores each individual use of a card and transmits information relating to the time and amount debited, and downloads such information to a clearing centre to enable the latter to keep a log of individual card usage and thereby enable fraud detection.

In a card charging system, especially for public transport services, there is included: (a) a card read/write unit for receiving one or more prepaid or credit cards; (b) a transaction recording-payment facility; and (c) a security module located between the card read/write unit and the transaction recording-payment facility, the recording-payment facility operable to receive signals from the security module to enable a purchase to be made in return for an amount of credit debited from said one or more cards, wherein a contactless concessionary card reading subsystem is connected to the security module, in addition to the card read/write unit for prepaid or credit cards. The system provides the benefit that it is capable of accommodating concessionary card reading subsystems and determining appropriate debiting associated therewith in addition to improved transaction recording and enhanced security.

A card charging system, especially but not exclusively for payment of public transport fares is described, having one or more card readers and a security and transaction device connected between the card reader(s) and a host facility and for transmitting information back to a clearing center, wherein the security and transaction device includes a number of non-volatile storage devices for error counting and transmitting related performance data back to the clearing center. A card charging system can include a security and transaction (TSM) device located between a smart card reader, such as a contactless card reader, and a host facility to enable a purchase to be made in return for a credit debited from the card, wherein the TSM device stores each individual use of a card and transmits information relating to the time and amount debited, and downloads such information to a clearing center to enable the latter to keep a log of individual card usage and thereby enable fraud detection. Where a (TSM) device is connected between a card reader and a host to enable a purchase to be made as described, amounts debited are communicated by the TSM to the clearing center in conjunction with a code uniquely associating that particular TSM with a particular host thereby to enable correct revenue apportionment.

摘要:
There is described a card charging system comprising: (a) one or more smart card reading devices; (b) a transaction recording-payment facility; and (c) one or more security modules located between the one or more reading devices and the transaction recording-payment facility. The transaction facility is operable to receive signals from the one or more security modules to enable a purchase to be made in return for an amount of credit debited from a card; the one or more security modules record individual use of the card in respect of time and amount debited. The system further includes a clearing center to which information is transmitted from the one or more security modules to order the clearing center to keep a record of the location of each security module, whereby the clearing center is enabled to keep up to date a log of individual card usage, the clearing center log including the time and location of each card transaction, as well as any remaining credit on the card, and wherein the clearing center incorporates means for identifying any inconsistencies in the log with respect to the card credit and the locations and times of transactions.
