摘要：
A portable consumer device includes a base, and a computer readable medium on the base. The computer readable medium comprises code for an issuer verification value and a supplemental verification value. The issuer verification value is used by an issuer to verify that the portable consumer device is authentic in an on-line transaction and the supplemental verification value is used to verify that the portable consumer device is authentic in an off-line transaction.
