Product Overview

The DO-QR36 is a multifunctional access control reader engineered for modern commercial, industrial, and institutional deployment. This device integrates ID/IC card reading, QR code scanning, and TCP/IP communication into a single embedded mounted unit, enabling system integrators, facility managers, and security contractors to consolidate authentication methods without additional hardware layers. Designed for continuous operation in high-traffic environments, the DO-QR36 supports Wiegand 26/34 output, making it directly compatible with existing access control panels and third-party controllers commonly used in large-scale projects.

Purchased by access control system integrators, building security contractors, IT infrastructure teams, and wholesale distributors, this reader solves the business problem of fragmented identification methods. Instead of deploying separate card readers, barcode scanners, and network controllers, a single DO-QR36 unit handles RFID credential verification, QR code ticket validation, and network-based access management. For procurement teams evaluating long-term supply agreements, the do rfid reader manufacturer provides stable production capacity, batch consistency across bulk orders, and technical support for project-level deployment.

Key Features

• Dual Authentication Support – Reads both 125KHz EM standard ID cards and ISO14443A/B IC cards (including M1 S50/S70, FM1208 CPU cards, SRIX4K, and second-generation ID cards), plus QR and 2D barcodes from screens or printed media.
• Multi-Protocol Communication – RJ45 10/100M TCP/IP with extensible wireless WiFi and Bluetooth options. Supports TCP, UDP, and HTTP protocols for flexible network integration.
• Wiegand 26/34 Output – Emits card serial numbers and associated QR code data in standard Wiegand format, ensuring compatibility with most third-party controllers and legacy access control systems.
• Built-in Voice Output – Integrated amplifier and speaker with approximately 150 customizable voice prompts, enabling audible feedback for entry grants, denials, alerts, or instructional messages.
• Relay Outputs for Device Control – Two 250V/5A relay outputs, one dedicated to door unlock and one expansion output for controlling door openers, lights, water valves, or other auxiliary equipment.
• Comprehensive Inputs – One gate input, one exit button input, and one alarm input, all on a single 12V DC power supply operating at less than 600mA.
• 10,000 Transaction Log Capacity – Onboard storage for access events, useful for audit trails, attendance tracking, or security compliance reporting.
• 4,000 Card Capacity – Sufficient credential storage for medium to large facilities including office buildings, factories, warehouses, and institutional campuses.

Technical Specifications

Industrial Applications

The DO-QR36 is deployed across a range of commercial and industrial access control scenarios where multiple credential types must be accepted at a single entry point. Typical applications include:

• Office Building Access – Employees use ID cards or QR codes from mobile credentials; visitors receive time-limited QR codes for temporary entry.
• Factory and Warehouse Security – Workers authenticate via RFID cards while delivery personnel present QR codes for logged entry and exit.
• Parking and Transit Gates – QR codes from parking reservations or transit passes are scanned alongside RFID badges for staff access.
• Educational Campuses – Students and staff use IC cards or QR codes printed on enrollment documents; the device logs all transactions for attendance recording.
• Hospital and Laboratory Controlled Areas – Dual authentication options allow for strict access control while the 10,000-event log supports compliance audits.
• Event and Stadium Entry – QR codes printed on tickets are scanned at high throughput; the Wiegand output integrates with existing turnstile controllers.

For system integrators managing multiple sites, the TCP/IP interface enables centralized configuration and event retrieval. The relay outputs can trigger door strikes, barriers, or auxiliary devices directly, reducing the need for separate control modules.

OEM / ODM Manufacturing Support

The do rfid reader manufacturer offers comprehensive OEM and ODM customization for the DO-QR36, allowing procurement teams to adapt the reader to specific project requirements. Available customization options include:

• Voice Prompt Customization – Replacement or addition of voice files for branded welcome messages, multi-language instructions, or industry-specific alerts.
• Wiegand Output Configuration – Adjustment of data format mapping to match existing controller requirements or proprietary credential structures.
• Enclosure and Mounting Modifications – Adjustments to the embedded mounting bracket, housing color, or front panel labeling for brand consistency.
• Firmware Parameter Adjustments – Modification of timeout durations, relay activation sequences, and communication timeout values to match site-specific workflows.
• Custom QR Code Parsing Rules – Implementation of proprietary QR code formats for ticketing, membership, or visitor management systems.

OEM partners receive technical documentation, sample units for integration testing, and direct engineering support during the customization phase. The factory maintains stable production runs to ensure that bulk orders delivered across multiple phases maintain identical hardware and firmware revisions.

Factory Production Advantages

As a dedicated do rfid reader manufacturer with 17 years of production experience in the RFID and access control industry, the factory behind the DO-QR36 provides measurable advantages for wholesale buyers, distributors, and long-term project partners:

• Stable Production Capacity – Manufacturing facilities in Dongguan support continuous production runs with volume flexibility from sample quantities to full container shipments.
• Batch Consistency – Every production batch undergoes the same assembly process, component sourcing, and quality inspection, ensuring that readers ordered months apart perform identically in the field.
• Fast Lead Times – Sample orders ship within 1–5 working days. Bulk orders are produced and dispatched within 7–30 working days depending on quantity and customization complexity.
• In-House Quality Inspection – Each unit is tested for RFID read range, QR code decode accuracy, Wiegand output integrity, network connectivity, and relay function before packing.
• Export Shipping Support – Strong cooperation with DHL, FedEx, TNT, UPS, and EMS for air freight, plus sea freight forwarding for large-volume orders. Buyers may also arrange their own forwarder.

For procurement professionals evaluating long-term supply relationships, the factory provides consistent pricing structures, technical support for integration, and the ability to scale production as deployment projects expand across multiple sites.

Bulk Supply & Project Deployment Support

The DO-QR36 is available through wholesale and bulk supply channels specifically structured for system integrators, distributors, and contractors managing multi-site access control installations. The do rfid reader manufacturer supports project-based procurement with the following commercial advantages:

• Volume-Based Pricing – Tiered pricing for orders of 50, 100, 500, or more units, with discounts applied at each volume threshold.
• Phased Delivery Scheduling – Orders for large-scale deployments can be split into multiple shipments aligned with construction or installation phases.
• Technical Integration Support – Direct access to engineering resources for Wiegand compatibility testing, TCP/IP network configuration guidance, and relay wiring documentation.
• RMA and Warranty Service – 2-year warranty covering manufacturing defects. Warranty service is honored for damage not caused by human mishandling. Post-warranty repair service is available at cost.
• Sample Qualification – Free sample units are available for qualification testing (inquiry required). Buyers can verify integration with their access control panels and network infrastructure before committing to volume orders.

Distributors and system integrators benefit from a single hardware platform that supports both card-based and QR code-based credentials, reducing SKU complexity in their product catalogs and simplifying field installation training.

Frequently Asked Questions

Can the DO-QR36 work with my existing Wiegand-based access control panel?
