AuthorizID Corporate 1000 35-Bit Clamshell Proximity Cards – 125 kHz Wiegand RFID Access Control Credentials for HID-Compatible Systems

Corporate 1000 35-Bit Proximity Cards for Enterprise Access Control, Corporate Campuses & High-Security Facilities

The AuthorizID Corporate 1000 35-Bit Clamshell Proximity Card is a professional-grade 125 kHz RFID access control credential engineered for security integrators, access control installers, and enterprise security administrators who require reliable, HID-compatible credentials. Operating on the widely deployed Corporate 1000 35-bit Wiegand format, these cards deliver seamless compatibility with a broad range of enterprise access control panels and readers without the facility code limitations of standard 26-bit credentials.

The Corporate 1000 format uses a 35-bit data structure that supports a significantly larger card number space than the standard HID H10301 26-bit format, making it ideal for large organizations, multi-site deployments, and corporate campuses where duplicate facility codes and card numbers are a concern. These clamshell cards are compatible with systems from Lenel, Software House, Genetec, Honeywell, Bosch, S2 Security, and other major access control platforms that accept Wiegand input from Corporate 1000-encoded readers.

Built in the classic thick clamshell housing, these proximity cards are durable enough for daily badge use, clip attachment, and high-traffic environments. The clamshell form factor protects the internal RFID antenna and chip from physical damage, extending credential lifespan in demanding field conditions.
