Product Overview

The DO-QR88 Access Control QR Code RFID Card Reader is a dual-technology identification terminal designed for secure entry management and personnel authentication. This unit integrates QR code scanning and contactless RFID reading into a single compact enclosure, allowing system integrators and project contractors to deploy a unified access control solution across commercial buildings, office premises, co-working spaces, and gated communities. The reader supports multiple output interfaces including Wiegand 26/34, RS232, RS485, and TCP/IP, ensuring backward compatibility with existing access control panels and third-party security systems. Manufactured by do rfid reader manufacturer with over two decades of production experience, the DO-QR88 is built for stable long-term operation in high-traffic environments where reliability and reading speed are critical.

Key Features

• Dual Identification Method – Simultaneously reads QR codes and contactless RFID cards (EM or Mifare) from a single device, reducing hardware duplication at entry points.
• High-Speed Reading – QR code and card reading speed is less than 200 milliseconds, enabling smooth flow during peak entry periods.
• Adjustable Reading Range – Supports a reading distance of 0 to 20 cm, with typical RFID reading range between 3 and 6 cm depending on tag type and environmental conditions.
• Multiple Output Interface Options – Choose between Wiegand 26/34, RS232, RS485, or TCP/IP to match existing access controller inputs, simplifying retrofit and new installation projects.
• Wide Voltage Input – Operates on DC 4 to 15 V, providing flexibility for various power supply configurations in different deployment sites.
• Tempered Glass Panel – Front panel constructed from tempered glass for scratch resistance and durable daily use in public access areas.
• Multi-Color LED Status Indicators – Red indicates operating status, yellow provides feedback confirmation, and green signals network connectivity, allowing quick visual troubleshooting.
• SDK for Secondary Development – Software development kit available for Windows and Linux platforms, enabling custom integration into proprietary access control or time-attendance systems.
• Compact 86×86 mm Form Factor – Standard wall-box size fits existing mounting frames, reducing installation complexity for large-scale projects.

Industrial Applications

Building contractors, security system integrators, and facility management companies deploy the DO-QR88 in environments where both card-based and QR code-based access control is required. Typical commercial applications include office lobby turnstiles, parking garage entry points, staff canteen doors, co-working space meeting rooms, gym membership gates, and residential apartment main entrances. The reader’s ability to handle two credential types from one unit reduces wiring complexity, lowers per-door hardware cost, and simplifies user enrollment processes for property managers. Wholesale buyers sourcing for multi-site rollouts benefit from batch consistency across units, ensuring uniform reading performance and identical mounting dimensions across all project locations.

System integrators working with existing Wiegand-based controllers appreciate the plug-and-play compatibility of the DO-QR88, which eliminates the need for controller upgrades during reader replacement projects. For new installations, the TCP/IP option enables centralized management and remote configuration via networked access control platforms. The available SDK also allows developers to embed QR code reading functionality into custom software solutions for visitor management, temporary access issuance, and event ticketing applications.

OEM / ODM Manufacturing Support

Do rfid reader manufacturer offers full OEM and ODM customization for the DO-QR88, allowing security hardware brands, system integrators, and distribution partners to configure the reader according to project-specific requirements. Customization options include front panel branding with company logos or property management identifiers, adjustment of output format to match proprietary controller protocols, modification of LED behavior for specific feedback sequences, and tailored firmware for unique timing or access logic requirements. OEM partners receive dedicated engineering support during the development phase, sample validation before mass production, and consistent batch quality across all delivered units. This manufacturing flexibility is particularly valuable for large-scale government, education, and corporate campus projects where uniform hardware appearance and behavior are mandatory.

Factory Production Advantages

As an experienced manufacturer of access control and RFID identification products, do rfid reader manufacturer operates with stable production capacity capable of fulfilling bulk orders for national distribution networks and international project shipments. Every unit undergoes pre-shipment quality inspection covering reading accuracy, output signal integrity, power consumption, and physical damage check. Tempered glass panels are sourced from qualified suppliers and tested for surface durability before assembly. The production line supports fast lead times: sample orders are typically completed within 1 to 5 working days, while bulk production orders for quantities up to 5,000 units require approximately 7 to 15 days depending on customization complexity. This turnaround reliability enables distributors and project contractors to meet tight construction schedules without hardware supply delays.

For logistics, do rfid reader manufacturer has extensive export experience and can arrange shipping via express courier (DHL, FedEx, TNT, UPS), air freight, or sea freight depending on order volume and delivery urgency. Trade terms including EXW, FOB, FCT, CIF, and CFR are all supported, and necessary customs documentation such as Certificate of Origin, FTA, Form F, and Form E can be provided to facilitate smooth clearance at destination ports. This end-to-end logistics capability reduces administrative burden for wholesale buyers and allows them to focus on their own deployment and sales activities.

Bulk Supply & Project Deployment Support

Wholesale customers and project contractors purchasing the DO-QR88 in volume benefit from stable pricing structures, reserved production slots for recurring orders, and technical documentation including wiring diagrams, SDK documentation, and installation guides. For large-scale deployments exceeding 100 units, do rfid reader manufacturer offers pre-configuration services where output interface, LED behavior, and reading parameters are set at the factory before shipment, reducing on-site commissioning time for installation teams. Compatibility with major access control controller brands is verified during pre-production sampling, so integrators can confidently specify the DO-QR88 for projects where integration with existing infrastructure is a prerequisite. Distributors seeking long-term supply partnerships receive priority support for inventory planning, sample allocations for new product evaluations, and responsive communication for technical inquiries during project execution.

Frequently Asked Questions

Q1: What interfaces does the DO-QR88 support for connecting to access control panels?
The reader supports Wiegand 26 and 34, RS232, RS485, and TCP/IP. The interface can be selected according to your existing controller input requirements.

Q2: Can the DO-QR88 read both QR codes and RFID cards simultaneously?
Yes, the reader is designed to process both credential types from a single unit, enabling mixed-mode access control without requiring separate readers for each technology.

Q3: Is the DO-QR88 compatible with third-party access control software?
Yes, the Wiegand output works with most standard access control panels. For custom integration, the SDK for Windows and Linux allows developers to interface the reader with their own software platforms.
