Abstract
In an authentication-data issuing system based on unique time, a master computer (1) creates authentication data on the basis of an elapsed time measurement indicated by an unique time generating device (6) and transmits the created authentication data to a lower-level computer (2A), which further delivers the authenticating data to a still-lower-level computer (3A). The lower-level computer and still-lower-level computer sequentially impart respective unique additional data to the authentication data and then transmits the resultant additional-data-imparted data to a lowest-level vending machine (5). The lowest-level vending machine (5) also imparts its unique additional data to the authentication data, received from the still-lower-level computer, to create unique authentication data and records the thus-created unique authentication data on a prepaid card (20) to be issued thereby. Simultaneously, the ultimately-created unique authentication data is sent from the vending machine, through the still-lower-level computer and lower-level computer, back to the master computer (1) for registration therein. When the thus-issued prepaid card (20) is used on a pachinko machine in a pachinko house under the control of the master computer (1), the pachinko machine reads the unique authentication data recorded on the card, and the thus-read data is collated with the data registered in the master computer (1) to ascertain the authenticity of the card.

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.
