TRANSACTION SYSTEMS AND ASSOCIATED METHODS FOR ENCHANCED ACCOUNT BALANCE AND STATUS MANAGEMENT

摘要

A computer implemented method of performing a transaction using a payment account, typically handled by a payment account manager (PAM), comprises the steps of: receiving a first message from a top up terminal indicating that funds have been transferred to the payment account; setting or adjusting a funds limit of the payment account based on information in the first message; receiving an authorisation or pre-authorisation request from a first terminal and commencing a funds aggregation; receiving a second message indicating a pre-defined amount of funds which may be used in the transaction; blocking an amount of the funds limit of the payment account equivalent to the pre-defined amount; and sending an authorisation response to the first terminal. As a result, the PAM can send data to indicate that a card associated with the payment account is not fit for travel. In one aspect of the invention, a transit authority is able to write bypassing data to the card so as to bypass a deny list that would otherwise have blocked the card from being used for a transit journey.
