GAO Tek Inc. is an international leading provider of embedded development tools, telecommunication testers, electronic measurement instruments, video surveillance & alarm and other electronic products that serve the needs of electronic professionals in the world and is incorporated in both the USA and Canada.

GAO Tek is a result of the strong engineering talent and capabilities within GAO Group. It started operating in 2001 as GAO Engineering to supply development tools to engineers and developers in the embedded field. The business grew rapidly thanks to the quality and the high value to price ratio of its products. Over time the product offerings of GAO Engineering has expanded to cover telecom products, test and measurement instruments, IT products, as well as a strong line of highly popular RFID products. In July 2006, GAO Engineering was renamed to GAO Tek Inc. to reflect its ever broadening range of RFID product lines. To cater to the ever growing RFID related business and products a new company, GAO RFID Inc., was created and spun out of GAO Tek Inc.

GAO Tek employs state-of-the-art e-commerce technologies to facilitate online ordering by its customers and backs it with a no nonsense product guarantee and timely support by highly qualified technical staff. The competitive advantage of GAO Tek over its competitors lies in its ability to deliver value, benefits, and quality at substantially better prices.
