History

A concise historical narrative of NAICS Code 561621-05 covering global milestones and recent developments within the United States.

  • The "Card Key Systems" industry has a long history dating back to the 1970s when the first electronic access control systems were introduced. These systems used magnetic stripe cards to grant access to buildings and were quickly adopted by businesses and government agencies. In the 1980s, the industry saw a shift towards more advanced systems that used smart cards with embedded microchips. These cards could store more information and were more secure than magnetic stripe cards. In recent years, the industry has continued to evolve with the introduction of mobile access control systems that use smartphones to grant access. In the United States, the industry has seen significant growth in recent years due to increased demand for security systems in commercial and residential buildings. Notable advancements in the industry include the development of cloud-based access control systems, biometric authentication, and the integration of access control systems with other security systems such as video surveillance and intrusion detection.
