Abstract
An automated transaction system employs a card maintaining an account balance and a terminal for dispensing an article of value and debiting the card's balance. The card has a secure, resident microprocessor which executes an interactive handshake recognition procedure with a secure, resident microprocessor in the value dispensing section of the terminal prior to actuating a requested transaction. In the preferred form, the handshake procedure operates by an exchange of encrypted words between the card microprocessor and the dispenser microprocessor using corresponding encryption algorithms and a secret key number, and the card microprocessor providing a command signal to the dispenser microprocessor only upon successful completion of the procedure. The automated transaction system is particularly suitable as a postage metering terminal having a postmark printer as the value dispensing section. Postage is printed only if the handshake procedure is executed between the card microprocessor and the printer microprocessor. The postal terminal also receives a rate card for computing postage automatically, and prints an invisible authentication mark along with the postmark to discourage counterfeiting. The terminal can be configured to print standard form waybills for postal and private carrier services by loading waybill information from an IC ROM services card. The balance in the user card is refilled in a refilling terminal using a master card which maintains a master account balance and a supervisor card which is in the custody of an authorized person.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
