Publication number: 20240070646Abstract: Disclosed herein are system, method, and computer program product embodiments for generating a virtual card number (VCN) associated with a credit card having a primary account number (PAN). The algorithm used matches the last 4 digits of the VCN to the last 4 digits of the PAN. By matching the last 4 digits of the VCN to the PAN, customer confusion is avoided, and VCNs may be more widely deployed, reducing the number of PAN reissuances that occur. The implementation of this feature is possible using the specific technique disclosed herein that uses multiple, rotating bank identification numbers (BIN) to expand the universe of available PANs to scales that can support a working implementation. The approach further describes accepting both a PAN card verification value (CVV) and a VCN CVV to authorize transactions. The approach also allows the synchronizing of expiration dates between a VCN and a PAN to further ease the burden of administering VCNs.Type: ApplicationFiled: January 31, 2022Publication date: February 29, 2024Applicant: Capital One Services, LLCInventors: Paul Y.
