How to Set Up & Manage Cards
Initial Card Setup
- Power off the board and connect jumper cap to pins 2–3. Restore power — the green LED will flash three times.
- Consecutively swipe two blank cards: the first programs the "Add Card," the second programs the "Del Card." The red LED will flash rapidly.
- Power off again, reconnect the jumper cap to pins 1–2, then restore power. Your master cards are now active.
Adding & Removing Users
- Add User: In standby mode, swipe the "Add Card," then swipe each user card to enroll, then swipe the "Add Card" again to exit.
- Delete User: In standby mode, swipe the "Del Card," then swipe each user 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 clear all enrolled credentials.
Ideal Use Cases
- Building intercom systems and door access panels
- Apartment complex entry management
- Office and light commercial access control
- OEM/embedded security system development

Frequently Asked Questions
Q: What card types does this RFID access control board support?
A: The board supports both 125KHz EM/ID proximity cards and 13.56MHz IC (smart) cards, making it compatible with a wide range of existing credential systems. You can use either type depending on your current card infrastructure.
Q: How many users can be stored on this RFID access control module?
A: The board can store up to 2,500 unique user card credentials directly in its onboard memory — no external database or PC connection is required for day-to-day operation.
Q: Do I need special software to add or delete users?
A: No software is needed. User enrollment and deletion are managed entirely through physical "Add Card" and "Del Card" swipe sequences in standby mode, making on-site management fast and straightforward.
Q: Is this board suitable for outdoor intercom installations?
A: The board operates within a temperature range of -20°C to 60°C, making it suitable for embedded use in outdoor-facing intercom housings. However, it should be mounted inside a weatherproof enclosure if exposed to moisture or direct weather.
Q: What power supply does the RFID board require?
A: The module requires a DC 12V power supply and draws less than 100mA, making it compatible with most standard access control power supplies and energy-efficient for continuous 24/7 operation.
