It employs a <strong>proprietary protocol layer</strong> developed by <a href=\"/manufacturer/hid-global\">HID Global</a> that extends the ISO/IEC 14443 Type B physical interface with vendor-specific command structures and security mechanisms.</p><p>The chip utilizes load modulation for backscatter communication, with the reader generating the RF field and the tag modulating its impedance to transmit data. Anti-collision follows the ISO/IEC 14443 Type B bit collision detection scheme, though HID's proprietary implementation manages credential selection and session establishment beyond the base standard.</p><p>Memory architecture is organized into sectors with access control lists governing read, write, and authentication permissions. The <strong>Secure Identity Object (SIO)</strong> data model enables portable, multi-application credentials that can represent physical access control privileges across different systems.</p><p>Security operates through multiple layers: physical layer ISO/IEC 14443 Type B compliance, proprietary authentication commands, and application-layer encryption protecting credential data during transmission and storage.</p>","programming_notes":"<p>Reader compatibility requires <strong>HID Global iCLASS SE</strong>-enabled readers or multi-technology readers supporting the SE command set.
