Dual Frequency 125kHz + 13.56MHz USB RFID Card Reader

Product Overview

The DO-08N MF+EM dual frequency USB RFID card reader combines 125kHz and 13.56MHz reading capability in a single desktop unit, enabling system integrators and access control contractors to handle both EM ID cards and Mifare IC cards with one device. This USB RFID reader eliminates the need for separate readers when deploying hybrid card systems, reducing hardware costs and simplifying installation for commercial access control, attendance tracking, and identity verification projects.

Procurement teams and project managers choose this dual frequency USB reader when they need a single hardware interface to manage legacy 125kHz ID cards alongside newer 13.56MHz smart cards during system migration or multi-technology deployments. The plug-and-play USB connection allows direct integration with PC-based access control software, visitor management systems, and time attendance platforms without additional controller hardware.

Product Advantages

• Single device dual frequency support – Reads both 125kHz TK4100 ID cards and 13.56MHz Mifare IC cards, reducing inventory complexity for distributors and system integrators managing multi-technology environments.
• USB desktop convenience – Direct connection to any PC or laptop eliminates extra wiring and power adapters, simplifying deployment for office access control, membership management, and identity verification workstations.
• Fast card reading – 0.2-second read speed supports high-throughput environments such as employee check-in, visitor registration, and event access where queue speed matters.
• No manual data entry – Present the card to the reader and card data transfers directly to the application, eliminating keystroke errors and reducing staff workload during card issuance and attendance recording.
• Custom branding available – Logo printing on the reader surface enables OEM customers and corporate distributors to brand the hardware for their own product lines or internal deployment.

Technical Specifications

Industrial Applications

Access control systems – System integrators deploy this dual frequency USB reader at reception desks and security checkpoints to issue cards and verify credentials for employees and visitors. The dual frequency support allows organizations to phase in 13.56MHz smart cards while continuing to use existing 125kHz ID cards during transition periods.

Time and attendance tracking – Office managers and HR departments install the reader at entry points for clock-in and clock-out stations. The fast read speed and USB connectivity reduce bottlenecks during peak entry times and simplify software integration with attendance platforms.

Visitor management – Front desk staff use the reader to encode visitor badges and log entry times. The desktop form factor fits naturally on reception counters and integrates with visitor registration software running on a standard PC.

Membership and loyalty programs – Gyms, clubs, and co-working spaces use the reader at check-in counters to verify member cards. The dual frequency capability supports both legacy ID cards and newer smart cards without requiring hardware replacement.

Card issuance and encoding stations – Administrators use the reader at dedicated encoding workstations to program new cards before distribution. The USB connection allows direct communication with card encoding software for seamless data writing.

OEM / ODM Manufacturing Support

DO RFID Reader provides OEM and ODM services for the DO-08N MF+EM dual frequency USB reader, supporting bulk purchasers, distributors, and system integrators who require customized hardware for their product lines or project deployments. Customization options include:

• Logo printing on the reader surface according to customer design requirements
• Custom packaging for retail distribution or project kit assembly
• Firmware adjustments for specific card read protocols or data format requirements
• Bulk orders with consistent batch quality across production runs

OEM customers benefit from our manufacturing experience and production capacity, ensuring that each reader meets the same technical specifications across large-scale deployments. We support long-term supply agreements for distributors who need stable inventory replenishment and project-based ordering for system integrators with defined deployment timelines.

Factory Production Advantages

As an experienced RFID hardware manufacturer, DO RFID Reader maintains stable production capacity to support wholesale orders and project-scale deployments. Our factory production process includes:

• Consistent batch quality – Each production lot undergoes the same assembly and inspection procedures to ensure uniform read performance, housing fit, and USB connectivity across all units in an order.
• Fast lead times for bulk orders – Sample orders ship within 1–5 days, and bulk production orders complete within 7–30 days depending on quantity and customization requirements.
• Reliable component sourcing – Long-term supply relationships with component manufacturers ensure stable availability of reader modules, housings, and cables for continuous production.
• Quality inspection before shipment – Every reader is tested for read range, frequency accuracy, USB communication, and physical integrity before packaging to minimize field failures.
• Export packaging for international shipping – Readers are packed with sufficient protection for air and sea freight, reducing transit damage for overseas distributors and project customers.

Bulk Supply & Project Deployment Support

Wholesale buyers and system integrators choose DO RFID Reader as their dual frequency USB reader supplier for several practical reasons. The reader’s dual frequency support reduces the number of SKUs needed in inventory, simplifying stock management for distributors who serve customers with mixed card technology environments. The consistent read performance across temperature and humidity ranges (-25°C to 75°C and 10%–90% humidity) ensures reliable operation in both indoor office environments and semi-outdoor installation points such as gatehouses and entry kiosks.

For project contractors deploying access control or attendance systems across multiple sites, the USB plug-and-play interface reduces on-site configuration time. Each reader can be connected to a standard PC and begin reading cards within minutes, which is critical when commissioning dozens or hundreds of workstations under tight project deadlines.

Bulk order customers receive priority production scheduling and can coordinate delivery timing with their project milestones. We support phased shipment schedules for large deployments where readers need to arrive at multiple installation sites on specific dates.
