Product Overview

The DO-QR36-ID is a dual-technology contactless QR code and 125kHz ID card reader designed for access control and visitor management systems. This compact device combines RFID card reading with QR code scanning in a single 86x86mm form factor, making it a direct upgrade path for existing Wiegand-based access control installations. System integrators and project contractors deploy this reader in environments where both credential card users and mobile or printed QR code visitors need to pass through the same entrance point. By supporting EM 125kHz cards alongside QR codes, the reader eliminates the need for separate hardware for different credential types, reducing deployment complexity and per-door hardware cost.

Industrial buyers choose this reader for its compatibility with standard access control panels, visitor kiosks, and gate controllers that communicate via Wiegand 26 or Wiegand 34 protocols. The zinc alloy frame and acrylic panel provide physical durability for daily use in high-traffic commercial settings. For distributors and wholesalers supplying security equipment to building management companies, this product fills a specific requirement: a single reader that handles both existing 125kHz card users and new QR code-based visitor passes without replacing the entire access control infrastructure.

Key Features

• Dual Credential Support — Reads 125kHz EM ID cards and QR codes (including 1/2 code formats) from a single device, allowing phased migration from card-only to QR-enabled access without ripping out existing wiring or control panels.
• Standard Wiegand Output — Default communication uses Wiegand 26 or Wiegand 34 protocol, directly compatible with most third-party access controllers, gates, and turnstile systems. RS232, RS485, and TTL interfaces are also available for projects requiring serial communication.
• Fast Read Speed — 0.2-second card reading and QR code decoding speed ensures smooth pedestrian flow at office building entrances, community gates, and administrative hall checkpoints.
• Automatic Induction Scanning — The reader automatically detects and decodes a QR code when presented within the reading area, with a buzzer prompt confirming successful read. No manual button press required.
• Zinc Alloy Construction — Housing uses a zinc alloy frame with an acrylic front panel, providing impact resistance and daily wear protection for commercial deployment environments.
• Wide Operating Temperature Range — Rated from -20°C to 70°C, suitable for both indoor controlled environments and covered outdoor installations such as building entrance vestibules or parking gate stations.
• Visual Feedback Indicators — Blue LED indicates operational status, green LED confirms successful read, giving clear user feedback without relying solely on the buzzer.

Technical Specifications

Communication Interface and Wiring Definition

The DO-QR36-ID supports multiple communication interfaces to match different access control panel requirements. The default output is Wiegand 26 or Wiegand 34, which connects directly to most standard access controllers without additional conversion hardware. For projects requiring serial communication, RS232 and RS485 variants are available by request during ordering. TTL output is also offered for custom integration scenarios.

Wiegand 26/34 Wiring

• Red: 12V DC
• Black: GND
• Green: D0
• White: D1

RS485 Wiring

• Red: 12V DC
• Black: GND
• Brown: 485A
• Orange: 485B

RS232 Wiring

• Red: 12V DC
• Black: GND
• Blue: RX
• Yellow: TX

Distributors and system integrators should confirm the required interface with the project’s access control panel specification before bulk ordering. The factory can supply any of these wiring configurations on the same hardware platform, allowing a single SKU to serve multiple project requirements with a simple wiring change.

Industrial Applications

The DO-QR36-ID is deployed across a range of commercial and institutional access control scenarios where both cardholders and QR code visitors need to be processed through the same entrance point.

• Business Office Building Visitor Entry — Employees use existing 125kHz ID cards for daily access while visitors present QR codes issued by the reception kiosk or mobile app. The reader eliminates the need for separate card readers and QR scanners on the same door.
• Scenic Area and Tourist Site Staff Access — Staff enter using ID cards while temporary workers or contractors use time-limited QR passes. The dual read capability prevents the need for issuing temporary cards that may not be returned.
• Community and Residential Gate Management — Residents use their existing EM cards for gate entry while delivery personnel and guests scan QR codes sent via SMS or property management app. The reader integrates with existing Wiegand-based community gate controllers.
• Administrative Hall and Government Building Checkpoints — Employees use ID cards and visitors scan QR codes from appointment confirmation emails. The reader supports high-traffic throughput with 0.2-second response time.
• Supporting Gates, Turnstiles, and Visitor Kiosks — The reader can be mounted on pedestrian gates, full-height turnstiles, and self-service visitor kiosks, communicating with the host controller via Wiegand or serial output.
• Smart Home Integration — For residential smart home systems that accept Wiegand input, the reader provides both card and QR code access, allowing family members and service personnel different credential types.

OEM / ODM Manufacturing Support

As a dedicated RFID and QR code reader manufacturer, do rfid reader manufacturer offers OEM and ODM customization services for the DO-QR36-ID platform. Project contractors and system integrators who need custom enclosure colors, logo printing, modified reading ranges, or non-standard communication protocols can request these adjustments during the production planning stage. The factory supports customization of the acrylic panel design, housing material finish, and cable length.

For OEM buyers, the reader can be produced with your brand name and product labeling, with consistent batch-to-batch quality across production runs. ODM customers who require modified firmware behavior — such as custom data formatting on Wiegand output, specific QR code data parsing, or adjusted buzzer patterns — can work with the engineering team to define the requirements. The factory maintains stable production capacity for OEM orders ranging from hundreds to tens of thousands of units, with fast lead times for repeat orders once the specification is finalized.

Factory Production and Bulk Supply Advantages

do rfid reader manufacturer has been producing RFID and access control hardware for over 20 years, with dedicated production lines for card readers, QR code readers, and combination units. The DO-QR36-ID benefits from this manufacturing experience through consistent assembly quality, reliable component sourcing, and repeatable production processes.

For wholesale buyers and distributors, bulk supply is supported with batch consistency across multiple order cycles. Each unit undergoes functional testing including card read range verification, QR code decoding accuracy check, and Wiegand output signal testing before packaging. The factory can supply FOB, CIF, CFR, or EXW terms depending on the buyer’s logistics preferences.

For project contractors who need readers delivered in phases to match construction schedules, the factory can coordinate partial shipments while maintaining the same production batch quality. Large-scale deployment buyers benefit from the factory’s ability to maintain stable production capacity even during peak order periods, reducing the risk of supply chain delays affecting project timelines.

Bulk Order and Project Deployment Support

Project integrators and distributors ordering the DO-QR36-ID for multi-site deployments can rely on consistent reading performance, uniform wiring color coding, and identical firmware behavior across all units received. The factory supports bulk packaging options including individual box packaging, bulk carton packing with foam inserts, or custom kit assembly when the reader is packaged together with mounting screws, template, and documentation.

For large-scale projects requiring hundreds or thousands of units, the factory can provide pre-production samples for site testing and compatibility verification before mass production begins. Technical support is available for integration questions regarding Wiegand wiring, serial communication setup, and QR code format compatibility. Buyers who need to test the reader with their specific access control panel or visitor management software can request a free sample unit, paying only the shipping cost.
