Schlage HandPunch
GT-400 - Versatile, Flexible

The new smaller, improved Schlage GT-400 HandPunch terminal uses the size and shape of each employee’s hand for verification, making it fast, efficient and easy to use. With a large LCD screen and programmable soft keys, perfect for interactive workforce management kiosks, the new HandPunch GT-400 provides a conduit for employee communication right at the terminal. Its Linux platform offers multiple time and attendance/workforce management software developers with easy interface options.

“Our first totally redesigned HandPunch terminal in ten years, the new GT-400, coupled with a software provider, is a most effective solution for workforce management and lends itself to a diverse array of facilities and workgroups,” reports Randi Marchezak, Schlage biometric solutions marketing manager, time and attendance. “It provides daily, tangible benefits such as accurate record keeping, risk management and increased employee productivity that drives bottom lines and brings peace of mind to both employers and employees.”

Using biometrics to automate the collection of time and attendance data can reduce buddy punching (one employee clocking in or out for another), manual data review and correction time, and payroll error. HandPunch terminals are used in more biometric time and attendance systems than any other biometric technology. Millions of people throughout the world clock in and out of work daily with a hand geometry reader. Deployed properly, the HandPunch delivers a payback very rapidly.

The HandPunch GT-400 uses hand geometry - the length, thickness, and curvature of fingers or simply the size and shape of a user’s hand - to verify each employee. Hand geometry increases reliability and reduces privacy concerns over fingerprint and other biometric technologies. It takes measurements of the hand and converts them into a 20-byte numerical template. This template is then matched with the enrollment template and the user’s identity is verified. Hand geometry technology is not affected by tattoos, jewelry, fingernails, lotions, dirt, smudges or dust. The reading and verification process takes less than a second with impeccable reliability. During the process, the communication panel can display relevant messages to employees, promoting communication with management.

Administrators can download new firmware and application functionality through an Ethernet connection, without removing the GT-400 from the wall and disrupting productivity. They can also remotely diagnose the terminal for troubleshooting and maintenance without removing it from the wall. Antimicrobial coating embedded in platen, keypad and plastics inhibits the growth of bacteria.
