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 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.

1. A card charging system comprising:(a) a card reader for reading a card; (b) a transaction-recording payment facility; and (c) a security module located between the card reader and the transaction-recording payment facility, the security module operable to communicate with the transaction-recording payment facility to enable a purchase to be made in return for an amount of credit debited from the card, the system further comprising a clearing centre to which debited amounts are communicated from the security module in association with a unique code assigned to the security module enabling correct revenue apportionment for the particular security module, wherein re-programming the security module to change its unique code can only be carried out in the physical presence of the security module and requires its direct connection to a re-programming device at the clearing centre.
