The ZKTeco C3‑200 Plus is a robust, IP‑based access control controller engineered to provide secure and scalable access management for up to two doors. Built on a Linux operating system with a modern communication framework, this controller supports RFID card authentication, password verification, and dynamic QR code access. With a high user capacity of up to 100,000 and the ability to store up to 500,000 transactions, the C3‑200 Plus is well‑suited for small to medium business environments in Pakistan looking for reliable and expandable security solutions.

The controller integrates versatile interfaces including TCP/IP, RS‑485 (with support for ZKTeco’s RS‑485 protocols and OSDP v2.1.7), Wiegand, and USB, allowing seamless communication with ZKTeco readers and third‑party devices. Enhanced data security is implemented through AES 256‑bit storage encryption and AES 128‑bit encrypted communication between the controller, readers, and expansion modules. Standard access control features such as anti‑passback, access levels, group management, and global linkage ensure comprehensive access policies.
