Maintenance of virtual credit card pool for airline passenger vouchers

摘要

Methods and apparatus are disclosed for the maintenance of a virtual credit card pool for airline passenger vouchers. An example system includes server(s) that are configured to determine a target distribution of virtual credit cards within the virtual card pool for a current date-and-time. The server(s) are configured to, in response to determining that the current date-and-time corresponds with a predefined restocking time, for each card value: identify a current number of virtual credit cards within the virtual card pool; identify a threshold number of virtual credit cards based on the target distribution; compare the current and threshold numbers; in response to determining that the current number is less than the threshold number, transmit a request for virtual credit cards having the card value to an external server; and add the requested virtual credit cards to the virtual card pool upon receipt.
