The MF 21P Desktop Reader is a versatile and powerful tool designed to simplify card-based operations. It seamlessly bridges the gap between physical NFC cards and your digital systems by functioning as both a robust Mifare card reader/writer and a convenient keyboard emulator.
This compact, desktop-ready device is the perfect all-in-one solution for developers, integrators, and businesses looking to implement or manage card-based access, loyalty programs, data collection, or secure logins with unparalleled ease.

Key Features & Capabilities:
Flexible Connectivity: Connects directly to your workstation or system via USB, providing both power and a reliable data connection. It’s plug-and-play ready for the keyboard emulation function.
Advanced Mifare Card Handling: Read from and write to all major Mifare card types (including Classic 1K/4K, Ultralight, DESFire), enabling you to manage UIDs, authenticate, and securely read/write data blocks for a wide range of applications.
Integrated Keyboard Emulation (HID): Its standout feature is the ability to emulate keystrokes. Any data read from a card (like a card number or a predefined string) can be instantly output as keyboard input, allowing it to work instantly with any software that accepts text entry—web browsers, login screens, CRM systems, time & attendance software, or custom databases—with zero software drivers required.
Desktop Convenience: Designed for ease of use on a desk, point-of-sale, or reception area. Its user-friendly form factor includes clear visual/audible feedback (LED & buzzer) for smooth operation.
