Abstract: A reward card platform includes a database storing funding accounts, reward card purchase transactions, and aberrant activity rules. A first user interface enables purchasing reward cards, including controls to specify reward card parameters. A second user interface enables specifying rules to detect aberrant activity. The second user interface includes user interface controls to specify the rule parameters, including: specifying a moving window of time; specifying an aggregation type; specifying filtering; specifying aggregation grouping; and specifying a threshold value for triggering an alert. The platform includes a rules execution engine that runs periodically to evaluate each of the rules. For each rule, the engine identifies transactions whose timestamps fall within the moving window of time relative to a current time and satisfies the filters, then computes an aggregation of the transactions according to the aggregation type and aggregation grouping.

Abstract: A reward card platform includes a database storing funding accounts, reward card purchase transactions, reward card brand options, and denomination options. The platform provides a user interface for purchasing reward cards from multiple third party suppliers. The user interface commits reward card purchase transactions using the funding accounts and specified reward card brand and denomination options. The platform obtains reward card items from supplier APIs corresponding to specified reward card brand and denomination options. The platform includes a buffer storing reward card inventory items.

Abstract: A method and system are provided for communicating digitized data associated with a purchase made by expenditure of a monetary credit account, such as a gift card account. The digitized data may be or comprise audio, photographic or video data. A gift card may be provided that relates to a monetary credit account that may specify an expendable monetary value, a benefactor who initiated the account, and a beneficiary who may use the monetary card. The gift card may record of at least part of the monetary credit account. The system may enable the generation of an electronic message that includes digitized data representing a purchased item and the message may be communicated to a photo-sharing webservice and/or an address associated with the benefactor. The digitized data may be a photograph, icon or a graphic image and the purchased item may be a service, good, license, lease, rent, or permission.
