I. Pain Points of Traditional Access Control in Scenarios like Hotels, Rental Apartments, and Self-Study Rooms:

With the popularization of QR code technology and the changing lifestyle habits of the younger generation, traditional access control management methods have exposed numerous pain points in short-term rental and temporary access scenarios such as hotels, rental apartments, and self-study rooms.

1.Difficulty in Access Card Management: Cards are easily lost, difficult to retrieve, and can be duplicated. Permissions cannot be cleared promptly after check-out/lease termination, posing significant security risks.
2.Uncontrollable Password Access: Passwords are prone to leakage and cannot be traced. Frequent modification also causes inconvenience to users.
3.Inapplicability of Biometric Recognition: Facial/fingerprint recognition involves privacy concerns. For temporary and highly mobile groups like hotel guests/students, the enrollment process is cumbersome, leading to a poor user experience.
4.Risks with Generic QR Codes: Most QR codes generated by third-party mini-programs can be freely shared or screenshotted, leading to a mismatch between the "payer" and the "actual user," causing management confusion and business disputes. (See the screenshot of our QR code access control mini-program interface with the sharing function not disabled below).


Shenzhen Cerberus Technology Co., Ltd., based on its deep accumulation in QR code access control technology, has launched an exclusive QR code access control solution featuring "Anti-Sharing, Traceable, and Over-the-Air Authorization" specifically for the unique needs of these scenarios, relying on the WeChat Mini Program. This solution aims to strictly bind access rights to the user's identity through technical means, without the need for an additional app, ensuring simple operation and flexible authorization, and preventing unauthorized lending. Simultaneously, it provides managers with an efficient and convenient remote management tool, significantly enhancing management efficiency and security.

II. Core Advantages of the QR Code Access Control Solution


2.1. Zero-Development Deployment: Our solution requires no additional technical investment or programming skills from integrators. They can focus on installation and commissioning, with a ready-to-use system upon account activation. This enables faster quoting and quicker project deployment.
2.2. Anti-Sharing Control: Proprietary QR code mechanism with one-click deactivation of sharing and remote unlock functions, ensuring authorized, individual use and preventing multi-person use from a single credential
2.3.Private Branding:  Supports customizing the Mini Program name and uploading the Company LOGO (640*300 pixels) to enhance the integrator's brand image.
2.4.Over-the-Air Authorization: Authorization is performed in the backend using the mobile phone number. Guests enter via Access Control with QR Code immediately without register at the management office.
2.5. Multiple Security Mechanisms: The QR code refreshes every 5 seconds, has a 5-minute validity period, and employs anti-screenshot + blacklisting strategies to ensure secure usage.
2.6. SAAS Cloud Management: No deployment is required. Managements can remotely authorize tenants/members through the SaaS cloud platform without issuing physical cards or enrolling fingerprints/faces on-site, greatly reducing the management burden. This is particularly suitable for scattered apartments and chain scenarios.
2.7. Full Platform Compatibility: Supports Windows/Linux/Android systems, allowing management via computer or mobile phone, enabling operation anytime, anywhere.
2.8. Privacy Protection: The QR Code solution completely avoids the privacy leakage risks associated with collecting biometric information like facial data, complying with personal information security.
2.9. Door Lock Status Monitoring: When installed with an Electric Strike Lock or Electromagnetic Lock that provides feedback signals, the real-time open or closed status of the door can be displayed.
3.0. Downward Compatibility: System upgrades do not affect existing configurations, ensuring long-term stable operation.
