METHODS AND SYSTEMS FOR PUBLIC KEY INFRASTRUCTURE (PKI) ENABLED PRE-AUTHORIZED CREDIT CARD TRANSACTIONS

Abstract:

Disclosed are systems and methods for public key infrastructure (PKI) enabled pre-authorized credit card transactions. For example, a method for granting limited transactional authorization from an account associated with a primary cardholder and a companion cardholder may include receiving a request to grant limited transactional authorization from the account for at least one transaction between the companion cardholder and a merchant, generating a response to the request, wherein the response includes at least one limitation, authenticating the response based on identification information of the primary cardholder, obtaining a private primary cardholder key upon authentication of the response, encrypting the response with the obtained private primary cardholder key, and transmitting the encrypted response for authorization of the at least one transaction according to the limitation.
