Claim:
A method for a payment processing transaction comprising: at a secure storage device not controlled by a merchant and not actively connected to a secure payment system, capturing from a payment device unencrypted payment device data and customer identification data, encrypting the unencrypted payment device data, and storing the encrypted payment device data; and at a merchant payment system, establishing a connection between the secure storage device and the secure payment system, using a client application on the merchant payment system to read the stored encrypted payment device data from the secure storage device to generate a first payment processing request including the customer identification data and the encrypted payment device data without storing the encrypted payment device data at the merchant payment system such that the encrypted payment device data is not visible to the merchant, submitting the first payment processing request to the secure payment system, receiving a unique identifier associated with a customer account that was generated in response to the first payment processing request, submitting a second payment processing request to the secure payment system such that the merchant is required to identify the unique identifier of the customer account and not unencrypted payment device data or encrypted payment device data of the payment device, receiving a status from the secure payment system that the second payment processing request is approved, declined, or has experienced an instance of process failure, and deleting the stored encrypted payment device data from the secure storage device.
