METHOD AND SYSTEM FOR VIRTUAL ACCOUNT NUMBER-BASED TRAVEL EXPENSE CONTROLS AND ACCOUNTING.

摘要

A method for providing enhanced control of travel purchases includes: storing rule data entries, each entry including data related to an employer rule including a rule identifier and at least one data requirement; receiving a payment number request including a specific rule identifier, payment amount, and data fields; identifying a specific rule data entry where the rule identifier corresponds to the specific rule identifier; identifying a controlled payment number configured for use for a single payment transaction if data included in the data fields satisfies the at least one data requirement included in the specific rule data entry; transmitting the identified controlled payment number; storing a transaction record including the identified controlled payment number and data fields; receiving purchase data corresponding to a purchase made using the identified controlled payment number, the purchase data including the controlled payment number; and associating the stored transaction record with the received purchase data.
