Product details

The S4 Fingerprint + NFC + IC Card Access Control Board is the top model in this series, fitted with a metal-housing round fingerprint sensor — a tougher, weather-resistant reader with a threaded barrel that mounts cleanly through a door, panel or gate post. It unlocks three ways — by fingerprint, IC/RFID card, or your phone's NFC, and its wide DC 12V–120V input runs from almost any access-control power supply, car battery, or industrial DC source.

The board stores 50 fingerprints as standard (upgradable to 300 or 500) plus up to 10 admin fingerprints, and manages multiple IC/NFC cards alongside them. The onboard relay provides both normally-open (NO) and normally-closed (NC) dry contacts, so it can drive a 12V electromagnetic lock, electric strike, drop bolt, gate, siren, or appliance within the relay's rating.

Three switchable output modes cover almost any job: self-locking (toggle) (tap on / tap off), jog (momentary) (opens then auto-closes after a delay you set from 300ms up to 15 minutes, default 1 second), and inching (hold-to-run) (stays on only while a valid finger or card is held). Enrol and delete fingerprints or cards straight from the board using the admin finger/card, with buzzer + multi-colour LED feedback confirming each step.

Supplied with the control board in its enclosure, the metal fingerprint reader module (with cable), an IC antenna, and one blue IC key fob. Ideal for DIY access control, automotive, appliance and industrial control.

Frequently asked questions

How do I unlock it?

Three ways — fingerprint, IC/RFID card, or phone NFC. It stores 50 fingerprints as standard (upgradable to 300/500). See our full access control range.

Why is the S4 the top model?

The S4 is the top model in the S0 to S4 series. It uses a metal-housing round fingerprint sensor with a threaded barrel — tougher and more weather-resistant than plastic readers, and it mounts cleanly through a door or panel. Compare the full access control range.

What kind of lock can it operate?

The relay gives both NO and NC dry contacts, so it can drive a 12V electromagnetic lock, electric strike or drop bolt. Browse magnetic door locks.
