A transaction network contains a networked certificate authority, by which
one or more virtual certificates may be remotely defined and stored, such
as by an issuer user through a issuer web portal interface. An acquirer
user, through an acquirer web portal interface, may acquire one or more
virtual certificates, which contain a public key portion, as well as a
corresponding private key, which is established at the time of
acquisition, and is stored at the certificate authority. At a redemption
location associated with an acquired certificate, the acquirer (or an
alternate recipient of an acquired certificate to whom the acquirer has
communicated the established private key), submits the certificate
information, along with the established private key, to redeem the
certificate.
