About Us

GT Clocks has been serving the world’s leading Human Capital Management (HCM) solutions providers for almost 50 years. Continuous innovation has been at the heart of a strategy that has kept the organization at the forefront of technological advancement throughout that time.

From our humble beginnings, we now have operational hubs in both the US and Europe and clients across the globe. Our products and services have changed over time, but our philosophy remains the same; to be the supplier of choice for HCM partners seeking reliable and technologically advanced edge devices, data-entry terminals, or ‘timeclocks’ as many of our customers still call them. We don’t mind; we like being the ‘clock guys’.

We pride ourselves on the talented individuals that make GT Clocks different. From Operations through to Sales and Development we work collaboratively to deliver much more than just secure, smart environments.
