Claim 4:
5. A system for replenishing tokens in a payment device, comprising:
a payment device having a payment device processing unit and payment device memory, the payment device memory configured to store an authentication token for use in authenticating the payment device during a payment transaction;
a reader device having reader circuitry configured to interface with the payment device, the reader circuitry configured to obtain the authentication token stored in the payment device memory during the payment transaction when the reader circuitry is interfaced with the payment device;
a server communicatively coupled to the reader device to receive the obtained authentication token from the reader device during processing of the payment transaction, the server having a server processing unit and a server memory, the server processing unit configured to determine, based on the authentication token received from the reader device, whether to proceed with authorizing the payment transaction, the server processing unit configured to provide to the reader device a script and a new authentication token for the payment device, the script including an instruction for the payment device processing unit to store the new authentication token in the payment device memory; and
the reader device configured to provide the script and the new authentication token received from the server to the payment device via a communication path between the reader device and the payment device when the reader circuitry is interfaced with the payment device, the payment device processing unit configured to execute the script, when the reader circuitry is interfaced with the payment device, to store the new authentication token from the server in the payment device memory for use in a subsequent payment transaction.
