Legacy clock-and-data and Wiegand protocols were widely adopted in the early 1980s as the de facto standard for interoperability between access control readers and physical access controllers.

Organizations that don’t move to OSDP-based PACS solutions leave themselves extremely vulnerable to security threats. Related: HID Global Releases Cloud-Based Credential Management Solution Organizations that understand the benefits of OSDP can more easily support both current and future technology requirements. At the same time, it delivers other advantages that increase the value of adopting it, including increased flexibility and operational efficiency for the long term. Upgrading to access control systems that adhere to OSDP standards significantly enhances overall security. An example is the Open Supervised Device Protocol (OSDP), which was introduced a decade ago as an alternative to clock-and-data and Wiegand protocols that are now antiquated and vulnerable.

Physical access control technology has advanced as new threats and vulnerabilities emerged, security protocols were updated, and requirements for integration grew. Standards Evolve to Improve Interoperability This enables today’s PACS solutions to boost building security and performance while giving users the same kind of digital convenience at the office and in other buildings as they have come to expect at home. These solutions incorporate everything needed to connect to and interact with a building’s other security systems, services and enterprise applications.

To make this possible the latest access control solutions have moved to open architectures and standard communications protocols that ensure product interoperability and implementation flexibility, while making it simple and economical to upgrade to new capabilities. The marriage of access control with mobile and Cloud technologies has enabled it to deliver a host of connected-workplace experiences that depend on common understanding of trusted identities that define who individuals are and what benefits can be granted to them, so they can understand, assist with and even predict what they intend to do.

Already the ubiquitous solution for safeguarding people, places and things, it is now also uniquely positioned to help unleash the full potential of smart buildings, hospitals and government offices.

The physical access control system (PACS) is rapidly becoming the hub of smart building innovation.
