Product Overview
The Dual Frequency RFID Access Reader is a compact and reliable access control reader engineered by do rfid reader manufacturer for secure identification and entry management in commercial buildings, office complexes, parking facilities, and restricted industrial zones. This reader supports simultaneous operation at 125 KHz and 13.56 MHz, allowing system integrators and project contractors to deploy a single hardware platform that works across both legacy low-frequency card systems and modern high-frequency contactless smart cards. By combining dual-frequency reading in one enclosure, this reader reduces installation complexity, lowers inventory costs for wholesalers and distributors, and provides end users with a seamless migration path from EM4100-based credentials to NXP Mifare or DESFire-based security card systems. Designed for flush mounting in standard 86 mm electrical boxes, this reader meets common global wall box dimensions and supports Wiegand 26 or 34 output protocol, making it directly compatible with most third-party access control panels and controllers already deployed in the field.

Product Advantages for System Integrators and Distributors
System integrators and security project contractors choose this dual frequency reader because it eliminates the need to stock separate LF and HF reader variants for different customer sites. A single SKU covers both legacy 125 KHz credential populations and newer 13.56 MHz smart card deployments, reducing inventory complexity and simplifying on-site stock management for distributors and wholesalers. The standard Wiegand 26/34 output interfaces directly with existing access control panels from most major manufacturers without requiring protocol converters or custom firmware. For commercial properties managing mixed card populations during credential migration, this reader provides a transparent bridge between old and new technologies, avoiding costly multi-reader installations and reducing labour costs for deployment teams. The compact 86 mm form factor meets global wall box standards, making it suitable for retrofit upgrades in office towers, government buildings, data centres, and industrial staff entrances where minimal wall preparation is preferred.
Industrial Applications
- Office and Corporate Access Control — Employee entrance doors, meeting room doors, and lift lobby turnstiles where dual-frequency compatibility supports phased migration from proximity cards to secure smart cards
- Industrial Staff Entry Gates — Factory floor entrances and warehouse access points requiring durable readers that integrate with centralised attendance and security management systems
- Parking and Perimeter Gates — Pedestrian access gates adjacent to vehicle barriers where authorised personnel use contactless credentials for entry and exit logging
- Data Centres and Server Rooms — High-security internal doors where DESFire or Mifare credentials are required and legacy LF cards are still in use for temporary contractors
- Educational and Healthcare Campuses — Multi-building sites managing separate card populations across departments, requiring a single reader type for all entrance points
- Government and Institutional Buildings — Secure zones where credential standards are evolving and readers must support both current and legacy card technologies during the transition period
OEM / ODM Manufacturing Support
do rfid reader manufacturer offers full OEM and ODM customization for the Dual Frequency RFID Access Reader to meet the specific branding, protocol, and hardware requirements of large-scale projects and distributor networks. Customization options include enclosure colour and logo printing, customer-specific packaging and labelling, firmware adjustments for custom Wiegand bit formats or fixed card UID output, LED colour configuration, and beeper tone customisation. For OEM partners requiring private-label readers for their own security product lines, the factory supports end-to-end development from specification review to production validation and batch consistency testing. The production line is configured for both low-volume prototype runs and high-volume batch manufacturing, with each unit tested for frequency response, reading stability, and output integrity before packing. Technical documentation, wiring diagrams, and integration guides are provided in English and Chinese to support installers, system integrators, and project engineers during deployment.
Factory Production Advantages
As an experienced do rfid reader manufacturer, the factory operates with stable production capacity capable of fulfilling bulk orders ranging from several hundred to tens of thousands of units per month. The manufacturing process includes incoming component inspection, SMD soldering for the main logic board, assembly of the sensor module and antenna coil, functional frequency calibration, and final assembly into the plastic housing. Each unit passes a functional test station that verifies 125 KHz and 13.56 MHz reading performance across the full range of supported card types, Wiegand output integrity at both 26 and 34 bit formats, and correct LED and beeper operation. Production batch consistency is maintained through controlled sourcing of HF reader chips and LF transceiver modules, ensuring repeatable read range and stable electrical characteristics across all units delivered within the same order or across multiple replenishment shipments. For wholesalers and distributors managing long-term supply agreements, the factory offers reserved production capacity, raw material buffer stock, and coordinated shipping schedules that align with project milestones and installation timelines.
Bulk Supply & Project Deployment Support
Procurement teams managing large-scale access control rollouts benefit from the factory’s ability to supply consistent, batch-tested readers with fast lead times. Standard lead time is 3 to 7 working days after order confirmation for stock items, with production scheduling support for orders exceeding 1,000 units. Packaging options include individual boxed units for retail distribution or bulk carton packing for installer distribution. Shipping support covers EXW, FOB Shenzhen or Hong Kong, CIF, and CFR trade terms, with the factory experienced in preparing customs documentation such as CO, FTA, Form F, and Form E for international shipments. For project contractors who require staggered deliveries across multiple construction phases, the factory can coordinate partial shipments with consistent batch composition. This level of supply chain reliability is particularly important for system integrators who depend on uniform reader performance across hundreds of door points and cannot tolerate component variation between installation phases.
