RFID Access Control Module 125KHz 13.56MHz | 2500 Users

Asia-Teco H2002D Dual-Frequency RFID Embedded Access Control Module

The Asia-Teco H2002D is a compact, standalone RFID access control board designed for seamless integration into building intercom systems and door entry installations. Supporting both 125KHz EM/ID cards and 13.56MHz IC cards, this dual-frequency module stores up to 2,500 users and operates entirely without a PC or network connection — making it an ideal embedded solution for residential buildings, offices, and secure facilities.

Made in Mainland China.

Key Features

• Dual-Frequency Compatibility: Reads both 125KHz EM/ID cards and 13.56MHz IC cards for flexible credential management.
• Large User Capacity: Stores up to 2,500 user credentials directly on the module — no server required.
• Standalone Operation: Fully embedded design integrates directly into building intercom systems or door control panels.
• Quick Card Read Range: Reads cards from 1–10 cm for smooth, contactless access.
• Low Power Consumption: Operates on DC 12V with a working current under 100mA.
• Wide Temperature Range: Functions reliably from -20°C to 60°C, suitable for indoor and semi-outdoor environments.
• Lightweight Build: Weighs only 80g for easy installation in tight spaces.

How to Set Up the Master Card

1. Step 1: Power off the module. Connect the S1 jumper cap to pins 2–3. Restore power — the green LED will flash three times.
2. Step 2: Consecutively swipe two blank cards (the first becomes the "add card," the second becomes the "delete card"). The red LED will flash in short bursts to confirm.
3. Step 3: Power off again. Reconnect the jumper cap to pins 1–2. Restore power. Master card setup is complete.

Adding & Removing Users

• Add a User: In standby mode, swipe the "Add Card," then swipe each user card to be enrolled, then swipe the "Add Card" again to exit.
• Delete a User: In standby mode, swipe the "Del Card," then swipe the user card(s) to remove, then swipe the "Del Card" again to exit.
• Delete All Users: In standby mode, swipe the "Del Card," then the "Add Card," then the "Del Card" again to exit.

Ideal Applications

• Residential apartment building intercom integration
• Office and commercial door access systems
• Embedded OEM access control board projects
• Gated community entry points
• Any installation requiring contactless card-based entry management

Frequently Asked Questions

Q: What types of RFID cards are compatible with the H2002D access control module?

A: The H2002D supports two card frequencies: 125KHz EM/ID cards and 13.56MHz IC cards. This dual-frequency design makes it compatible with a wide range of standard proximity credentials used in building intercom and door access systems.

Q: How many users can the RFID access control board store?

A: The H2002D embedded access control module can store up to 2,500 user credentials directly on the board without requiring an external server or software, making it ideal for medium-to-large residential and commercial installations.

Q: Can this module work as a standalone unit without a computer or network?

A: Yes. The H2002D is a fully standalone embedded module. All user management (adding, deleting, and clearing users) is performed using master cards and jumper settings directly on the board — no PC, internet connection, or management software is needed.

Q: What is the reading range of this RFID access control module?

A: The card read distance is 1 to 10 centimeters, enabling smooth and reliable contactless card detection for door entry and intercom access applications.
