Access Control Wiegand RFID Reader – 125kHz & 13.56MHz Multi-Frequency Card Reader

DO RFID Reader presents a robust access control RFID reader engineered for commercial and industrial deployment. This reader supports both 125kHz and 13.56MHz frequencies, enabling compatibility with a broad range of credential types including EM4100, TK4100, Mifare Classic, Mifare Plus, and NTAG series. With native Wiegand 26bit and 34bit output protocols, the reader integrates directly with existing access control panels, door controllers, and time attendance systems without additional configuration. Designed for system integrators, security contractors, and facility managers who require a reliable, field-proven card reader that works across mixed-technology environments.

Building owners and project planners often face the challenge of managing multiple credential formats across different buildings or tenant spaces. This reader eliminates that friction by supporting both low-frequency (125kHz) and high-frequency (13.56MHz) cards in a single device, reducing hardware inventory, simplifying installation logistics, and lowering total cost of ownership. Whether you are retrofitting an older facility with legacy 125kHz badges or deploying a new HF-based secure access system, this reader delivers consistent read performance and protocol stability.

Product Overview

The DO RFID Reader access control Wiegand reader is a multi-frequency, multi-protocol card reader purpose-built for physical access control, door entry, parking management, and personnel identification systems. It reads passive RFID tags operating at 125kHz (EM, HID-compatible formats) and 13.56MHz (Mifare, NTAG, ISO 14443A) with a single read head, eliminating the need for separate readers for different credential types. The Wiegand 26bit and 34bit interfaces are natively supported, ensuring direct drop-in compatibility with the vast majority of commercial access control panels on the market today.

System integrators and security distributors choose this reader because it reduces SKU complexity—one reader covers both LF and HF requirements—while maintaining the wiring simplicity of standard Wiegand output. This is particularly valuable for large-scale deployments where credential migration from 125kHz to 13.56MHz is planned, as the same hardware can read both technologies during the transition period.

Technical Specifications

Industrial & Commercial Applications

This Wiegand RFID reader is deployed across sectors where reliable credential verification and simple panel integration are essential. System integrators specify this reader for office building access control, multi-tenant residential entry, parking lot gates, warehouse personnel gates, and industrial facility perimeters. Distributors serving the security channel stock this reader as a universal replacement unit that reduces SKU count and simplifies customer support.

In manufacturing and logistics environments, the reader is used for staff identification at restricted zones, tool crib access, and time-and-attendance checkpoints. Its dual-frequency capability allows sites running legacy 125kHz badge systems to gradually migrate to 13.56MHz smart cards without requiring a forklift upgrade of all readers at once. This phased migration capability directly reduces capital expenditure and operational disruption for facility managers.

Commercial property owners and security contractors benefit from the reader’s standard Wiegand interface, which eliminates controller compatibility concerns. Whether integrating with Lenel, Honeywell, Bosch, HID, or other major access control platforms, the reader functions as a drop-in peripheral with no additional drivers or middleware required.
