GT-400 Terminal User’s Guide
Principles of Operation
The GT-400 terminal uses low-level infrared light, optics and a CMOS (IC chip) camera to capture a
three-dimensional image of the hand. Using advanced microprocessor technology, the terminal
converts the image to an encrypted electronic template. It stores the template in a database with the
user’s ID number. To gain access, the user enters his or her ID number using the terminal keypad or
uses an optional, built-in card reader. The terminal prompts the user to place his or her hand on the
terminal’s platen. The terminal compares the hand on the platen with the user’s unique template. If the
templates match, the terminal records the transaction for processing.
Database Synchronization
Synchronization, when used in this guide, refers to the process by which the database is updated on
both the terminal and the host application. Synchronization only occurs on networked terminals. When
synchronization occurs, the terminal and the host application compare their databases and make sure
they both have the most current data. Every synchronization results in the host and terminal databases
being identical.
Examples
• A user punches in on the terminal. When synchronization occurs, the punch transaction is sent
to the host application.
• A user is created on the host and added to the terminal. When synchronization occurs, the
terminal requests any changes from the host and the host sends the new user to the terminal.
Command Menus
Command menus are the menus in the terminal that are used to configure the terminal. The command
menus can be accessed by pressing and then within three (3) seconds from the ready
screen. If the terminal is a new terminal and has no users, the command menus will immediately
appear. After the administrator has been created, verification will be required to access the command
menus.
Verification
Verification refers to the process of placing the hand on the terminal platen as a part of the
authentication process. Authentication consists of entering a user identification number on the
terminal's alpha-numeric keypad and verification of the hand.
