Embedded RFID Access Control Module 125kHz 13.56MHz 9–30V DC
Dual-Frequency Embedded RFID Access Control Module
Take command of your entry points with this versatile embedded RFID access control module. Supporting both 125kHz (ID/EM4100) and 13.56MHz (IC/S50) card frequencies, this compact controller is engineered for seamless integration into gates, doors, turnstiles, and custom access systems. With a wide operating voltage range of DC 9–30V, it fits into virtually any installation environment — from small offices to industrial facilities.
Note: The ID module operates at 125kHz; the IC module operates at 13.56MHz. Please purchase the correct variant for your card type. Remote control modules must be added separately when ordering.

Operating Instructions
Add Admin Card
Short-circuit S2 to the 0 end while powered off, then restore power. The red and green LEDs will alternate. Swipe two cards consecutively — a green LED flash confirms success. The first card becomes the "Add Management Card" and the second becomes the "Delete Management Card."
Add User Card
In normal working state, swipe the Add Management Card (green LED flashes), then swipe the user card you wish to enroll, then swipe the Add Management Card again to complete the operation.
Delete a User Card
In normal working state, swipe the Delete Management Card (red LED flashes), then swipe the user card to be removed, then swipe the Delete Management Card again to confirm deletion.
Delete All Cards
In normal working state, swipe the Delete Management Card (red LED flashes), then swipe the Add Management Card and wait 5 seconds. The green LED will recover, confirming all cards have been cleared.

Frequently Asked Questions
Q: What is the difference between the ID module (125kHz) and the IC module (13.56MHz)?
A: The ID module operates at 125kHz and is compatible with EM4100 cards and similar low-frequency credentials. The IC module operates at 13.56MHz and works with S50 (MIFARE Classic) cards and compatible high-frequency credentials. Choose the module that matches your existing card infrastructure.
Q: How many user cards can this RFID access control module store?
A: The module supports a user capacity of up to 2,000 cards, making it suitable for small businesses, office buildings, and medium-scale access control installations.
Q: Does this module work with standard Wiegand readers?
A: Yes. The module features a Wiegand 26 (Wg26) interface input, supporting reader cable runs of up to 100 meters — ideal for installations where the reader needs to be positioned far from the controller.
Q: What power supply do I need for this RFID module?
A: The module accepts a wide DC input range of 9V to 30V and draws 60–80mA during operation, so it is compatible with most standard DC power supplies used in access control systems.
