USB Desktop UHF RFID Card Reader and Writer

Overview

The D-615 is a compact, plug-and-play desktop UHF RFID reader designed for fast and reliable tag encoding and reading. Featuring a USB driver-free design, it can operate as a virtual COM port or simulate a keyboard (HID) to directly input tag data into any software without complex wiring. It boasts a stable read range of 0-50cm and can process up to 50 tags simultaneously. With built-in LED and buzzer indicators, and comprehensive SDK/DLL support for secondary development (C++, C#, Java), it is the perfect cost-effective tool for access control, membership management, and desktop inventory.

Applications & Key Benefits

Desktop Membership & Access Control

• Application: Issuing and encoding RFID membership cards, employee ID cards, or hotel key cards at front desks.
• Key Benefit: Instant data entry. In USB HID mode, the reader acts like a keyboard, automatically typing the card ID into your existing management software. No complex programming is needed for basic card enrollment.

Retail & POS Checkout

• Application: Quick reading of UHF tags for retail items, VIP cards, or anti-counterfeiting labels at the point of sale.
• Key Benefit: Compact and clutter-free. Its small size saves valuable counter space, while the 0-50cm read range ensures fast, reliable scanning without the cashier needing to position the tag precisely.

IT Asset & Document Tracking

• Application: Desktop scanning of tagged files, folders, or small IT assets for localized inventory.
• Key Benefit: Multi-tag processing. It can read up to 50 tags simultaneously (with a cache of up to 330 tags), allowing you to quickly scan a stack of documents or a small box of equipment in a single pass.

Software & System Integration

• Application: Integrating RFID reading capabilities into custom ERP, WMS, or ticketing software.
• Key Benefit: Comprehensive SDK. The provision of DLLs, Android SDKs, and source code across multiple languages (C++, C#, Java, etc.) makes it extremely easy for developers to build custom applications and output formats.
