INTEGRATION NOTES
Where it fits
Evaluate this configuration for a USB-connected NFC terminal where your application also needs a local screen. Plan what the screen should show, when it should change and which software component will control it.
Integration choices
The manufacturer link for Round leads to the Round + OLED Display USB product. This page follows that exact listing. It identifies 13.56 MHz operation and ISO/IEC 14443 A/B plus ISO/IEC 15693 support; the SDK provides the reader integration path.
The bare Round OEM TTL UART module is a separate product. A UART display version is also listed separately. Keep the display, interface and enclosure selection explicit when comparing quotations.
Ask for a firmware-specific display example before committing to the application design. The cover is the manufacturer’s µFR Zero series illustration, so request a photograph and drawing of the selected Round display unit.
Prepare a quotation
Send the card or tag, host operating system, required NFC commands, expected screen content and quantity. Include the desired mounting position and any additional modules.

About this reader
Is this the Round reader without a display?
No. The verified manufacturer listing is specifically Round + OLED Display with USB. A bare OEM UART module and other interface variants require a separate selection.
Will the display show my application data automatically?
Confirm the display commands and firmware for your workflow. A display-equipped reader still requires software that produces the intended screen content.
