Product Overview
The DO-QR88 Access Control RFID Card Reader with QR Code Scanner is a dual-technology identification terminal designed for building apartment access, commercial office entry, and secured facility management. This reader combines EM or 13.56 MHz RFID card reading with QR code scanning in a single compact unit, allowing system integrators and project contractors to deploy a unified access control solution without requiring separate hardware for card and credential-based entry. The device supports multiple output interfaces including Wiegand 26/34, RS232, RS485, and TCP/IP, making it compatible with most existing access control panels and third-party security systems. Procurement teams and distributors looking for a stable, long-term supply of multi-format access readers for large-scale deployments will find the DO-QR88 suitable for projects requiring both physical card authentication and digital QR code verification.
Product Advantages
Dual Authentication in One Unit
The DO-QR88 eliminates the need for separate card readers and QR scanners by integrating both reading technologies into a single housing. This reduces installation complexity, cabling requirements, and overall hardware costs for building apartment access control, office lobby security, and gated community entry points. Facility managers benefit from simplified inventory management and consistent user experience across multiple entry locations.
Wide Interface Flexibility
With support for Wiegand 26/34, RS232, RS485, and TCP/IP, this reader can be integrated into legacy access control systems as well as modern IP-based networks. System integrators do not need to replace existing controllers or panels when upgrading to QR-enabled access. This backward compatibility is a critical factor for commercial retrofit projects and large-scale phased deployments.
Fast Read Speed for High-Traffic Areas
The reading speed of under 200 milliseconds ensures smooth throughput in busy environments such as apartment building entrances, office lobbies, and staff access gates. Users present their card or QR code once and gain entry without noticeable delay, reducing queue buildup during peak hours.
Industrial-Grade Construction
The front panel uses tempered glass, providing resistance to scratches, impacts, and daily wear in public access areas. The combination of plastic rear housing and glass front offers a balance of durability and lightweight installation, suitable for both indoor and sheltered outdoor mounting positions.

Industrial Applications
Building Apartment Access Control
Property managers and housing associations deploy the DO-QR88 at main entrances and shared facility doors to manage resident and visitor access. Residents use RFID cards or fobs for daily entry, while visitors receive time-limited QR codes via smartphone or printed pass. This dual method reduces key management overhead and eliminates the need for physical key duplication.
Commercial Office and Co-Working Spaces
System integrators install this reader in office lobbies, meeting room doors, and floor access points. Employees use existing proximity cards, and temporary workers or guests scan QR codes sent to their mobile devices. The wide voltage input and flexible interface options simplify integration with existing building management systems.
Gated Communities and Residential Complexes
For perimeter gates and pedestrian access points, the DO-QR88 provides a reliable entry solution that works with both legacy RFID credentials and modern mobile-based passes. Distributors supplying hardware to residential security projects benefit from the unit’s compatibility with multiple controller brands via selectable Wiegand and serial output formats.
Educational and Institutional Facilities
Schools, universities, and government buildings use this reader for staff and student access to restricted areas. The SDK enables custom software development for integration with attendance tracking, visitor management, and time scheduling systems.
Industrial and Warehousing Entry Points
In manufacturing facilities and logistics centers, the DO-QR88 controls access to production floors, storage zones, and administrative sections. Bulk purchasers and project contractors choose this unit for its stable performance across varying environmental conditions and its ability to work with both card-based and digital credentials in mixed-use deployments.
