Access Control QR Code RFID Card Reader – DO-QR888

Product Overview

The DO-QR888 is a dual-function access control reader engineered for commercial and industrial environments where both QR code scanning and RFID card reading are required in a single compact unit. Designed for system integrators, security contractors, and facility managers, this reader supports EM and Mifare card technologies alongside rapid QR code decoding, making it suitable for upgrading legacy access control systems or deploying new multi-factor authentication projects. Its slim 86×86 mm form factor fits standard wall boxes, simplifying installation in office buildings, parking garages, coworking spaces, hospitals, and industrial facilities where reliable identification and access logging are essential for operational security and compliance.

Product Advantages

• Dual authentication in one device – Eliminates the need for separate QR and RFID readers, reducing hardware costs and installation complexity for system integrators managing large-scale deployments.
• Wide voltage input (DC 4–15 V) – Compatible with most existing access control power supplies, making retrofitting straightforward for facility upgrade projects.
• Multiple interface options – Wiegand 26/34, RS232, RS485, and TCP/IP allow seamless integration with legacy controllers and modern networked access platforms, giving distributors and project contractors flexibility across different site requirements.
• SDK available for secondary development – Enables software developers and OEM partners to embed reader functionality into custom access management or time-attendance platforms, supporting branded solutions for resale.
• Tempered glass front panel – Provides scratch resistance and a professional appearance suitable for high-traffic commercial entrances, while simplifying routine cleaning and maintenance.

• Operating system support: Windows and Linux
• LED status indicators – red (power/working), yellow (feedback), green (network)
• Reading speed less than 200 ms for smooth user flow at busy entry points
• Reading distance 0–20 cm for cards and QR codes depending on environment and media
• Three LED colors provide clear visual feedback for users and security personnel
• Available SDK for custom integration and OEM/ODM projects

Technical Specifications

Industrial Applications

The DO-QR888 is deployed by security system integrators and facility management teams in environments that require fast, reliable dual-factor authentication. Typical applications include:

• Office building access control – Employees present QR code credentials from mobile apps or tap RFID badges for entry, reducing physical key and card replacement costs.
• Parking and gated communities – Supports resident and visitor access via temporary QR codes, while maintaining permanent RFID card access for regular users.
• Coworking and shared workspaces – Members use mobile QR codes for day passes, while monthly members use RFID cards, giving operators flexible credential management without adding reader hardware.
• Hospitals and clinics – Staff use RFID badges for rapid entry, while visitors receive temporary QR codes at reception, improving security and visitor tracking without slowing traffic.
• Industrial and logistics facilities – Combined card and QR reading allows gate operators to manage permanent employees and temporary contractors through a single reader, simplifying access policy enforcement.

For distributors and project contractors supplying to these verticals, the DO-QR888 reduces inventory complexity because one SKU supports both card and QR credential types, lowering stock holding while meeting diverse customer requirements.
