Hirsch 4090 Prox PVC Disk - 26 Bit AWID26

The Hirsch 4090 Prox PVC Disk is designed for organizations using 125kHz proximity technology with 26-bit AWID26 formatting for physical access control systems. This compact adhesive credential offers a versatile solution for adding proximity functionality to existing ID badges, cards, or non-metallic surfaces without replacing current credentials.

Commonly used in commercial facilities, educational institutions, healthcare environments, government buildings, and industrial sites, the Hirsch 4090 disk provides reliable contactless access performance in a discreet, low-profile form factor. Its self-adhesive backing allows it to be securely applied to existing credentials or objects, making it a cost-effective option for upgrading access control systems.

Programmed using 26-bit AWID26 formatting, these credentials require a facility code ranging from 0–255 and a unique card number between 0–65,535. Organizations ordering programmed credentials will typically provide their existing facility code and numbering sequence to ensure compatibility with their current access control infrastructure.
