RFID Access Control PCB Module 125KHz/13.56MHz – 15,000 Users

Dual-Frequency RFID Embedded Access Control Module – Up to 15,000 Users

The LUCKING DOOR H3003 RFID Access Control PCB Board is a compact, high-capacity embedded module designed for building intercoms, door access systems, and standalone security installations. Supporting both 125KHz EM/ID cards and 13.56MHz IC cards, this versatile module handles up to 15,000 registered users — making it ideal for residential complexes, offices, and multi-unit buildings.

Made in Mainland China.

Key Features

• Dual-Frequency Compatibility: Works with both 125KHz EM/ID cards and 13.56MHz IC cards for maximum flexibility.
• Large User Capacity: Stores up to 15,000 user credentials directly on the module — no external server required.
• Compact PCB Form Factor: Measures just 10 × 3.8 × 0.2 cm and weighs approximately 80 g, making it easy to embed into existing intercom or access panels.
• Low Power Consumption: Operates at DC 12V with a working current under 100 mA — energy-efficient for continuous 24/7 use.
• Wide Operating Temperature: Functions reliably from -20°C to 60°C, suitable for indoor and sheltered outdoor installations.
• Quick Card Read Distance: Reads cards from 1–10 cm for smooth, contactless entry.
• Easy User Management: Add or delete individual users or perform a full user wipe directly from the module using designated admin cards — no software needed.

Card Setup Guide

Initial Card Setup:

1. Power off the unit. Connect the S1 jumper cap to pins 2–3, then restore power. Wait for three green light flashes.
2. Swipe two consecutive blank cards (the first card acts as the "add card", the second as the "delete card"). The red light will flash in short bursts to confirm.
3. Power off again, reconnect the jumper cap to pins 1–2, restore power. Your admin cards are now programmed.

Adding Users: In standby mode, swipe the "Add Card," then swipe each user card you want to register, then swipe the "Add Card" again to exit.

Deleting a User: In standby mode, swipe the "Del Card," swipe the card 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" to confirm a full wipe.

Ideal Applications

• Building intercom systems
• Apartment complex or office door access
• Embedded OEM access control hardware
• DIY smart door entry projects
• Multi-tenant property management systems

Frequently Asked Questions

Q: What types of RFID cards are compatible with the H3003 access control module?

A: The H3003 supports both 125KHz EM/ID proximity cards and 13.56MHz IC smart cards. This dual-frequency capability makes it compatible with a wide range of existing access cards and key fobs commonly used in residential and commercial buildings.

Q: How many users can be stored on this RFID access control PCB board?

A: The module can store credentials for up to 15,000 individual users directly on the board. No external database or internet connection is required, making it a fully standalone solution ideal for large multi-unit buildings or office complexes.

Q: Do I need special software to add or remove users from the RFID module?

A: No software is needed. User management is handled entirely through the physical admin cards (Add Card and Del Card) set up during initial configuration. You can add individual users, delete specific users, or perform a complete user wipe using simple card-swipe sequences in standby mode.

Q: What power supply does the H3003 RFID access control module require?

A: The module operates on a DC 12V power supply with a working current of less than 100 mA, making it energy-efficient and compatible with standard access control power supplies used in most building installations.
