How do hotel electronic door locks work？

Hotel Electronic Door Locks are intelligent locking systems that combine electronic technology, mechanical structure, and network communication. Their working principle can be broken down into the following core components:

1. Core Components

  • Lock Body: Includes the mechanical bolt and a motor-driven extension mechanism (used for automatic unlocking/locking).
  • Control Module: Built-in microprocessor (CPU) responsible for verifying identity information and controlling the lock’s action.
  • Identity Verification Unit: Equipped with different modules based on the lock type, such as a card reader, keypad, fingerprint sensor, camera (for facial recognition), etc.
  • Power Supply: Typically powered by batteries (such as 4 AA batteries), with some models supporting external power sources or low battery warning features.
  • Communication Module: Networked locks may support Wi-Fi, Bluetooth, ZigBee, or proprietary networks for remote management.

2. Workflow

Step 1: Identity Verification

  • Card Verification (Magnetic Cards / RFID Cards / NFC Cards):
    • Magnetic Cards: Store room number and expiration data via a magnetic strip; the lock’s magnetic head reads the data when the card is swiped.
    • RFID/NFC Cards: Use radio frequency technology, where the card reader senses encrypted data (e.g., room number, validity period) from the card chip.
  • Password Verification: The user enters a preset temporary password, which the system checks for correctness and validity.
  • Biometric Verification (Fingerprint / Facial Recognition): The sensor collects biometric data and compares it with a stored template (usually done locally, without uploading to the cloud).

Step 2: Data Processing

  • Control Module decrypts and verifies the input information:
    • Local Verification: The lock stores valid keys or permission lists and performs offline verification (no internet required).
    • Cloud Verification (for networked locks): Data is sent to the hotel server to confirm the status of permissions (e.g., validity period, whether the card is disabled).

Step 3: Locking and Unlocking

  • After successful verification, the control module triggers the motor to retract the bolt and unlock the door.
  • If verification fails, an error is displayed (e.g., red light, beep sound), and the bolt remains locked.

3. Network and Remote Management

  • Real-time Monitoring: The lock status (locked/unlocked, battery level) is synced to the hotel management system via the network.
  • Dynamic Authorization: The front desk can remotely grant or revoke access (e.g., extend room access, automatically disable access after check-out).
  • Access Logs: Locking/unlocking records (time, method) are stored for security auditing.

4. Security Mechanisms

  • Encryption Technology: Cards or passwords use dynamic encryption (e.g., DES, AES algorithms) to prevent duplication or cracking.
  • Tamper Alarm: The lock triggers an alarm if it is tampered with, and some models can send notifications to the management system.
  • Backup Unlocking: A mechanical keyhole or emergency power interface (e.g., Type-C charging) is provided in case the battery is drained.

5. Power Supply and Battery Life

  • Battery life typically ranges from 6 months to 2 years, with low battery warnings via indicator lights or mobile system notifications.
  • Some locks are designed with low power consumption (e.g., sleep mode) and only wake up during operations to save energy.

6. Extended Application Scenarios

  • Temporary Permissions: Cleaning staff can be given time-limited access, and hourly rooms will automatically expire.
  • Integrated Systems: The lock integrates with the hotel Property Management System (PMS) for automatic room assignment and synchronization with check-out.

Summary

Hotel electronic door locks replace traditional keys with electronic identity verification, combining encryption and networking technology to enhance convenience while ensuring security. The key features include “dynamic permission management” and “offline/online dual verification,” making them a crucial component in modern hotel automation.

What Does the Elevator Card Access System Bring to Hotels?

An elevator card access system is a security measure used in hotel management, commonly found in hotels, apartments, office buildings, commercial buildings, or other high-rise structures. By implementing a simple elevator access control panel, an intelligent elevator system enhances building security and access control effectively.

Private Elevators vs. Public Elevators

There are many differences between elevators equipped with access control systems and public elevators that lack such systems.

First, elevators with card access control require users to have a specific access card or key card to operate the elevator. This means that only authorized users with the appropriate credentials can access certain floors or areas, providing an extra layer of security. The card acts as a mobile credential, allowing users to enter the elevator and access restricted floors.

In contrast, public elevators do not require any form of identity verification. Anyone can use the elevator to access all floors of the building, which poses a security risk, as unauthorized individuals may enter restricted areas.

What Does the Elevator Card Access System Bring to Hotels?

Installing Elevator Card Access Systems

Why does an elevator card access system enhance security? What does it bring to hotels?

Access Control for People Moving In and Out

Once an elevator control system is installed, a public elevator becomes a private one; it essentially transforms into an intelligent elevator.

Private elevators have strict access control measures to ensure that only authorized individuals can use them. Several types of access systems are used, including key card readers, elevator keypads, or biometric scanners. Biometric technology is more advanced and secure, as it verifies the user’s identity before granting access, and registers the user in the security system.

Restricted Floors Offer Extra Protection

Private elevators often have floor restrictions, meaning only people with valid access cards can reach certain floors. This helps protect the security and privacy of individuals who need access to specific areas of the building.

Enhanced Security for Customer Access Experience

Compared to public elevators, intelligent and private elevators provide more safety features. The entire access control system includes monitoring systems, emergency communication functions, and cloud-based access systems, allowing management to audit elevator activity at any time.

Public Elevators Without Access Control Devices

Public elevators lack the monitoring capabilities of intelligent elevators, making hotel security lower and making it harder to identify individuals who may engage in suspicious behavior.

Open Access to All

Public elevators are designed for general use, with no special credentials required to access them. Typically, anyone who needs to use them, such as mall customers or visitors, guests, and employees in the building, can access them.

Limited Security Measures Lead to Vulnerabilities

While public elevators may have basic security features like emergency buttons and cameras, they lack the advanced access control systems of private elevators. This means unauthorized individuals can freely use the elevator and access any floor without restrictions.

Strangers Sharing Space Burdening Workflow Access

Public elevators serve more people, often used by multiple tenants or visitors within a building. Compared to private elevators, this can lead to longer waiting times and overcrowding during peak hours.

In summary, private elevators provide enhanced security by restricting access to specific individuals or groups, while public elevators are open to a wider range of users but have limited security measures. The choice between private and public elevators ultimately depends on the security requirements and functionality of each specific building.

How Does an Elevator Card Access System Work?

Currently, most elevator systems use card access control systems to restrict access. Elevator card access technology works through readers connected to the elevator control system. Users are provided with access cards that grant them permission to reach certain floors. When the user approaches the elevator and presents the access card to the reader, the reader scans the card and verifies the user’s credentials.

Once the reader validates the user’s credentials, access to the designated floor or area is granted based on the permissions assigned to that specific card. If an unauthorized individual tries to enter, the system will deny access, and the elevator will not operate.

Single Card Swipe: Covers All Areas Allowed by the Hotel

When checking into a hotel, the staff registers your information at the front desk and gives you a card. This card not only allows you to use the elevator to reach specific floors, but also unlocks the room’s smart door lock when inserted into the power switch. One card connects you to all the areas you need to access, providing both convenience and security for various hotel areas.

What Does the Elevator Card Access System Bring to Hotels?

From a hotel management perspective, implementing an elevator card access system in a building can significantly reduce the need for manual staff and save costs. With a centralized system for automated access control, security protocols can be streamlined, minimizing the risk of unauthorized access, and optimizing operational efficiency.

Reducing Labor Costs

The automated elevator card access system eliminates the need for dedicated staff to monitor elevator usage, and no manual authorization is needed to access different floors. This not only saves on labor costs but also avoids awkward situations with introverted guests who may prefer not to be disturbed.

Efficient User Management

The elevator card access system allows staff or management to easily add, delete, or modify user credentials without the need for physical key management.

Heartsease

Only authorized individuals can access specific floors, giving both residents and management peace of mind, and creating a safer, more reliable environment for everyone. It also reduces unauthorized access and noise, providing guests with a quiet living environment.

Preventive Maintenance

Scheduling regular maintenance checks for the intelligent elevator system helps identify potential issues early and avoid costly repairs. By proactively performing maintenance tasks, the elevator’s lifespan can be extended, preventing unexpected downtime that may affect operations.

In general, investing in an elevator card access system not only improves security and convenience but also offers significant cost-saving benefits for building owners and managers. By automating the access control process with advanced technology, employee management practices can be optimized, and long-term financial efficiency can be achieved in operations.
