Product Overview

DO RFID Reader presents a comprehensive lineup of contact and contactless smart card reading solutions engineered for industrial identification, access control, payment systems, and automated data capture. As a dedicated RFID reader manufacturer, we supply two core products: the DO-39U USB Smart Card Reader for EMV and ISO 7816 chip card applications, and the DO-09D Desktop DIP RFID Reader for 13.56 MHz and 125 MHz contactless RFID tags. Both models are designed for system integrators, access control contractors, payment terminal distributors, and industrial project teams who require reliable, standards-compliant reader hardware for long-term deployment.

System integrators and procurement managers choose these readers because they eliminate driver compatibility issues, support multiple card protocols, and deliver consistent read performance across thousands of operational cycles. Whether you need a contact smart card reader for secure authentication or a driver-free DIP desktop reader for RFID tag identification, DO RFID Reader provides stable production capacity, OEM customization, and bulk supply for commercial and industrial projects.

Product Advantages

Both the DO-39U contact reader and the DO-09D contactless reader are manufactured with industrial-grade components and undergo batch consistency testing before shipment. This ensures every unit meets the same electrical and mechanical specifications, which is critical for large-scale deployments where replacement units must behave identically to the original hardware.

• Driver-Free Operation (DO-09D): The DIP switch configuration allows the reader to output card data directly without installing any software driver. This reduces integration effort for system integrators and eliminates operating system dependency issues across Windows, Linux, and Android environments.
• Multi-Protocol Support (DO-09D): Simultaneous support for 13.56 MHz and 125 MHz frequencies enables compatibility with MIFARE Classic, MIFARE DESFire, and EM4100 family tags, giving project managers flexibility to use existing card stocks without changing infrastructure.
• EMV Compliance (DO-39U): The DO-39U reader fully supports ISO 7816 Parts 1-3 with Class A, B, and C card voltages (5 V, 3 V, 1.8 V), making it suitable for financial payment terminals, PKI authentication, and government ID verification systems that require strict protocol adherence.
• 100,000 Insertion Cycle Durability (DO-39U): The contact card connector is rated for a minimum of 100,000 insertion cycles, which translates to years of reliable service in high-traffic environments such as retail point-of-sale, healthcare registration desks, and corporate access points.
• Fast Read Interval (DO-09D): With a read interval of less than 0.5 seconds, the desktop reader supports quick tag identification in applications like automated parking entry, personnel time tracking, and production line item verification.

FAQ

What is the difference between the DO-39U and the DO-09D readers?

The DO-39U is a contact smart card reader that requires physical insertion of an ISO 7816 chip card into the slot, making it suitable for EMV payment, PKI authentication, and secure ID verification. The DO-09D is a contactless DIP desktop reader that reads RFID tags via RF at distances up to 100 mm without physical contact, supporting both 13.56 MHz and 125 kHz tag types.

Does the DO-09D require driver installation?

No. The DO-09D is configured via DIP switches for output format and operates without any driver installation. It works with Windows XP, Windows CE, Windows 7, Windows 10, Linux, Vista, and Android operating systems using standard keyboard wedge or serial emulation.

Can the DO-39U read contactless RFID tags?

No. The DO-39U is a contact-only smart card reader. It reads and writes to ISO 7816 chip cards inserted into the slot. For contactless RFID tag reading, use the DO-09D or other contactless reader models from DO RFID Reader.

What is the maximum reading distance of the DO-09D?

The typical reading range for 13.56 MHz tags is up to 100 mm, depending on tag size, antenna design, and ambient RF environment. Larger tags and optimized placement can achieve maximum range.

Can I customize the output format of the DO-09D?

Yes. The DO-09D uses DIP switches to select output format such as decimal, hexadecimal, or reversed byte order. For custom output protocols or baud rate requirements, contact DO RFID Reader for OEM firmware customization.

What is the warranty period for these readers?

DO RFID Reader provides a 2-year warranty against manufacturing defects for both the DO-39U and DO-09D models. The warranty covers electrical and mechanical failures under normal operating conditions. Damage caused by improper use, physical impact, or unauthorized modification is not covered.

Can I get a sample before placing a bulk order?

Yes. Qualified system integrators, distributors, and project contractors can request samples for testing and validation. Sample orders are typically shipped within 1 to 5 days. Contact DO RFID Reader with your project details to arrange sample delivery.

How do I integrate the DO-39U with my payment terminal system?

The DO-39U uses a standard USB interface and complies with ISO 7816 Parts 1-3 for smart card communication. Integration typically involves driver installation (vendor-provided CCID driver) and application-layer protocol handling for EMV or proprietary card commands. Technical documentation and integration support are available from DO RFID Reader.

What is the minimum order quantity for OEM customization?

OEM minimum order quantities depend on the customization scope. Logo printing and packaging changes typically require 500–1000 units. Firmware or hardware modifications may have higher minimums. Contact DO RFID Reader with your requirements for a specific quotation.

How does DO RFID Reader ensure product consistency for large projects?

Each production batch undergoes functional testing including read range verification, protocol compliance check, power consumption measurement, and mechanical inspection. Components are sourced from qualified suppliers, and manufacturing processes are documented to maintain revision control across batches.
