Analysis of the application of three-in-one access control products of code scanning, card swiping and button pressing in hotels and homestays
With the rapid development of the smart hotel and homestay industry, the access control system is gradually upgrading towards integration and intelligence. The three-in-one access control products of code scanning, card swiping and button pressing have become a popular choice in the hotel and homestay industry due to their versatility and high compatibility. The following is a detailed analysis of its application methods, needs and advantages:

1. Hotel scenarios
Self-service check-in and permission allocation
Quickly complete identity verification by scanning code (dynamic QR code) or swiping card (IC card/ID card), combined with button password as a backup unlocking method. For example, guests can obtain dynamic QR codes through mobile phone APP, or collect physical cards at the front desk, and support emergency door opening by entering passwords145.

Hierarchical permission management
Differentiated permissions are set for different areas (such as guest rooms, gyms, and executive floors). Card swiping is suitable for long-term employees, code scanning is used for temporary visitor authorization, and button passwords are used as emergency backup plans23.

Elevator and access control linkage
After swiping a card or scanning a code, the elevator automatically unlocks the corresponding floor permissions, and the key password is used for manual operation in special circumstances (such as system failure).

2. B&B scenario
Distributed house management
The landlord generates dynamic QR codes for different houses through the cloud platform, and the tenant scans the code to check in; the physical card or password is suitable for long-term cleaning staff or maintenance workers.

Multi-room permission allocation
In the entire B&B, the main entrance uses code scanning or card swiping, and the room uses key passwords to achieve permission separation between public areas and private areas.

Flexible control of shared space
The public kitchen or garden is opened for a limited time by scanning the code, and the key password is used for night lock management.

Security and privacy protection

Dynamic QR code encryption technology prevents copying (such as RC4 algorithm);

Card swiping uses anti-copying IC card technology, and the password supports regular update;

Real-time alarm for abnormal unlocking behavior (such as multiple wrong password entries).

Convenience and user experience

Multi-mode unlocking adapts to different user groups (young people prefer to scan codes, while the elderly are used to swiping cards or passwords);

Contactless operation reduces the risk of cross-infection 

Efficient management and cost control

Remote permission issuance and revocation (such as automatic expiration of permissions after check-out);

Data statistics function optimizes operations (such as passenger flow peak analysis, energy consumption management).

Flexibility and scalability

Support linkage with hotel PMS system and smart home devices (such as automatic air conditioning when opening the door);

Modular design facilitates later upgrades (such as adding face recognition function).

Emergency and redundancy design

Backup power supply ensures normal use during power outages;

Mechanical keyhole as the final emergency plan.


3. Core advantages
Multi-mode compatibility, covering all scenario needs

Scan code: Dynamically encrypted QR code to prevent copying, support remote authorization and time-limited permissions;

Card swiping: High stability, suitable for high-frequency employee access;

Button: Low technical threshold, as a backup plan to ensure availability in extreme situations.

Safety redundancy design

The three-factor verification method complements each other to reduce the risk of single failure;

Record all operation logs in real time to facilitate tracing of abnormal events.

Significant cost-effectiveness

Reduce the cost of physical card production (scanning code relies on mobile phones);

Centralized management reduces manual maintenance costs.

Improve brand image and customer satisfaction

Technology-based operations enhance guest experience;

Contactless service meets the preferences of modern consumers.

Small and medium-sized B&Bs: give priority to offline password locks + code scanning functions to reduce network dependence4;

High-end hotels: need to be compatible with existing systems (such as elevator control, security linkage), and choose brands with strong scalability.
