What is Different from CoreStation (CS-40)?
CS-40 supports biometric (fingerprint and face) matching. However, CS-20 focuses on RFID matching, which can reduce the cost and complexity. Also, CS-20 can offer the relay power from itself, so you can connect a maximum of 2 relays without installing a separate power resource.
