Scramblepad Readers

Hirsch ScramblePad readers are high‑security access control endpoints designed to protect sensitive entry points with an advanced scrambled keypad that randomizes digit positions to prevent code pattern recognition or wear‑based attacks. Offered by Hirsch, these readers combine secure PIN entry with support for a wide range of credential technologies, including PIV, CAC, PLAID, legacy smart cards like MIFARE and DESFire, and proximity formats, providing flexible authentication options for demanding environments.

Built for integration with modern access control systems and compatible with protocols such as Wiegand, RS‑485/OSDP, Ethernet, and PoE, Hirsch ScramblePad readers are suitable for commercial, government, and high‑assurance facilities seeking robust PIN and multi‑factor authentication at the door. The family includes keypad‑only and combination keypad/reader models—some with embedded contact or contactless readers—making them ideal for installations requiring enhanced security without full infrastructure replacement.
