BQT 38bit

Everything you need to understand BQT 38bit

Card format Overview

A proprietary 38-bit card format used in access control systems, featuring a unique structure composed of 13-bit facility code, 19-bit access code, and 4-bit issue code, and 2 parity bits (even and odd), allowing for easy management and avoiding card number duplication for secure, contactless access.
