Abstract:
In a data communication system having a first data terminal for communicating a first packet of data and at least a second data terminal also for communicating a second packet of data, the first data terminal selectably utilizable by a user and including a first processing device and a first adaptor port having electrical terminals disposed thereat and at least selectably connected to the processing device and the second data terminal also selectably utilizable by the user including a second processing device and a second adaptor port having electrical terminals disposed thereat and at least selectably connected to the second processing device, an improvement of apparatus for identifying the first data terminal, said apparatus comprising:a portable storage device having a storage location for storing an identifier address the identifier address associated with the user, said storage device releasably engageable at any of the first data terminal and the at least the second data terminal such that, when engaged at the first data terminal and the first packet of data is to be communicated, a value of the identifier address stored at the storage location of said storage device is obtained therefrom and formatted together with the first packet of data to identify the first data terminal, and the first packet of data to be communicated therefrom, with the value of the identifier address and said portable storage device selectably released out of engagement at the first data terminal and engageable thereafter at the second data terminal such that, when engaged at the second data terminal and the second packet of data is to be communicated, the value of the identifier address stored at the storage location of said storage device is obtained therefrom and formatted together with the second packet of data to identify the second data terminal, and the second packet of data to be communicated therefrom with the value of the identifier address; a supportive adaptor engaged with said storage device, thereby to permit engagement of said storage device at any of the first data terminal and the at least the second data terminal; the supportive adaptor, together with said storage device engaged therewith, releasably received at the adaptor port of any of the first and at least second data terminals to electrically connect said storage device with the electrical terminals of any of the first adaptor port and the second adaptor port, thereby to permit the identifier address, stored at said portable storage device, to Dam with the user.
