1. A method of managing a payment device in a financial transaction between an issuer node and the payment device via a terminal across a payment network, the payment device being issued by an issuer or an agent of the issuer, the financial transaction being routed at an application layer from the issuer node to the terminal, comprising:

  • determining, by the issuer node, Issuer Authentication Data and extended Issuer Authentication Data associated with the payment device, wherein the extended Issuer Authentication Data comprises one or more updates to one or more updated values stored in a non-volatile memory of the payment device;

    packaging, by the issuer node, the extended Issuer Authentication Data in a first component configured to be executed by the payment device prior to receipt of a second component, wherein the first component comprises a first byte capacity;

    packaging, by the issuer node, the Issuer Authentication Data in a second component configured for completing the financial transaction and applying the Issuer Authentication Data, wherein the second component comprises a second byte capacity which is less than the first byte capacity of the first component;

    routing, by the issuer node, the first component through the payment network to the payment device;

    causing the payment device, upon receiving the first component, to provisionally store the extended Issuer Authentication Data in a volatile memory of the payment device without losing prior values corresponding to the extended Issuer Authentication Data stored in the non-volatile memory of the payment device; and

    causing the payment device, upon receiving the second component, to apply the extended Issuer Authentication Data to the non-volatile memory on the payment device to replace the prior values with the one or more updated values when the payment device has issued a confirmation that the financial transaction has been completed in accordance with the outcome requested by the issuer or the agent and upon successful verification of the Issuer Authentication Data.
