A method includes receiving a request to verify a dynamic security code included in a transaction authorization request message. The transaction authorization request message was generated in connection with a payment account transaction. The method further includes performing a verification process with respect to the dynamic security code to generate a verification result. In addition, the transaction authorization request message may be modified by adding the verification result to the transaction authorization request message. Also, the modified transaction authorization request message may be transmitted to an issuer of a payment account designated for use in the payment account transaction.

In an IC (integrated circuit) card, a selection signal is received from a user-actuatable switch to select between two different payment card accounts, each represented by a respective account indicator number stored in the IC component of the card. In response to the selection signal, a light-emitting diode indicator on the IC card is illuminated to indicate selection of a corresponding one of the payment card accounts.
