The Cassi-Rusco format originated as a proprietary access control technology designed to offer a more secure and controlled credential format than traditional magnetic stripe cards. It was widely adopted in commercial and government facilities where secure authentication was a priority. Over time, the **40-bit format** became a recognizable standard within older security systems, making Cassi-Rusco a trusted name in access control.

As security needs evolved, the limitations of Cassi-Rusco—such as the lack of encryption and vulnerability to duplication—led to the development of **more advanced credential technologies**. However, due to the widespread installation of Cassi-Rusco-compatible systems, the format continues to be used in many legacy environments today.
