# RFID & Password Door Lock Access Control System Set ## Introduction to RFID & Password Door Lock Access Control System Set An RFID & Password Door Lock Access Control System Set is a sophisticated security solution that combines radio-frequency identification (RFID) technology with keypad password entry. This dual-authentication method enhances security by requiring users to present an authorized RFID card, tag, or fob and/or enter a valid numeric code to gain access. These systems are widely used in residential, commercial, and industrial settings to control entry to doors, gates, and restricted areas. From my personal experience managing access for a small office, implementing an RFID & password system drastically reduced security incidents. We previously used traditional keys, which were often lost or duplicated without authorization. The new system provided detailed entry logs and the flexibility to revoke access instantly—a game-changer for our administrative control. ## How the RFID & Password Door Lock Access Control System Set Works ### Core Components and Operation The system typically consists of: 1. **Electronic Lock Mechanism:** Installed on the door. 2. **Reader/Keypad Combo Unit:** Mounted externally, featuring an RFID reader and a numeric keypad. 3. **Internal Control Panel/Module:** Houses the main controller and memory. 4. **Power Supply & Backup:** Often includes a battery backup for uninterrupted operation. 5. **RFID Credentials:** Cards, key fobs, or wristbands. The process is straightforward: a user presents their RFID credential to the reader or enters a PIN on the keypad. The control unit verifies the credential or code against its stored database. Upon a match, it sends a signal to the electric lock to disengage, allowing entry. Many systems allow for dual-factor authentication, requiring *both* an RFID scan and a correct password for higher security zones—a feature I highly recommend for server rooms or storage areas with sensitive inventory. ## Technical Specifications and Parameters * **Lock Type:** Electric Strike, Mortise Lock, or Magnetic Lock compatible. * **RFID Fre
