Dual Frequency USB Card Reader

The Dual Frequency USB Card Reader (Mifare 13.56MHz + UHF Long-Range RFID) is an enterprise desktop workstation engineered specifically for dual-band card identification, registration, access control enrollment, and POS transactions. Combining an ISO 14443A High-Frequency (HF 13.56MHz) engine and an EPC Gen2 Ultra-High Frequency (UHF 865–867MHz) transceiver, this device reads both smart credentials on a single compact USB pad.

[!IMPORTANT] Dedicated Read-Only Scanner (Not an Encoder/Writer):
This device operates strictly in Read-Only Mode. It is optimized for high-speed, error-free UID and EPC extraction directly into cursor focus via USB HID keyboard simulation. If your application requires writing EPC memory, reprogramming passwords, or encoding Mifare data blocks, please view our Dual Frequency UHF + 13.56MHz Desktop Reader Writer.

1. Dual-Frequency Radio Engine (13.56MHz + 865–867MHz)

• High Frequency (13.56 MHz): Natively reads UIDs from ISO 14443 Type A contactless cards including Mifare Classic 1K/4K, Mifare Ultralight, NTAG213/215/216, and Fudan F08 chips with 0–50 mm proximity touch.
• Ultra-High Frequency (865–867 MHz WPC India): Interrogates EPCglobal Gen2 / ISO 18000-6C long-range chips (Impinj Monza, NXP UCODE, Alien Higgs) within a calibrated near-field desktop range of 50–300 mm.
• Automated Frequency Discrimination: High-speed hardware polling alternates between HF and UHF interrogation cycles in under 50 milliseconds, reading whichever card frequency is presented with zero manual switching.

2. Plug-and-Play USB HID Keyboard Emulation

• Zero Driver Setup: Operates as a standard USB HID keyboard wedge on Windows 11/10/7, Linux (Ubuntu/Debian), macOS, and Android OTG.
• Instant Keystroke Output: Immediately outputs card serial number / EPC hex into active text fields in Microsoft Excel, TallyPrime, SAP S/4HANA, web browsers, or custom ERP systems followed by an automatic Enter key.
• Virtual COM Port Option: Switchable to high-speed virtual serial COM mode for headless POS terminals, gate controllers, and automated kiosk software using our OpenRFID SDK.

4. Ideal Enterprise & Institutional Applications

• Dual-Credential Campus Enrollment: Front-desk workstations registering hybrid student/employee cards used for both vehicular boom barriers (UHF) and library/turnstile access (Mifare).
• Time & Attendance Logging: Fast contactless tap-in scanning for factory muster points, IT park receptions, and corporate offices.
• Point-of-Sale (POS) & Canteen Management: Frictionless customer loyalty card lookup and prepaid cafeteria card identification.
• Visitor & Contractor Registration: Rapid scanning of visitor badges and parking passes directly into visitor management software without manual number typing.
