Frequently Asked Questions
What types of NFC tags can this encoder write to?
The Desktop USB NFC Encoder supports a wide range of HF RFID chips including NTAG213/215/216, NTAG424DNA, MIFARE Classic 1K/4K, MIFARE Ultralight/C, MIFARE Plus, and DESFire (optional). It is compatible with all ISO/IEC 14443 Type A tags and can write URLs, text, and custom data formats.
Can I write encrypted or locked data to NFC tags?
Yes, this encoder supports advanced encoding features including encrypted data writing, password protection, and permanent locking. The NTAG424DNA chip offers AES-128 authentication and SUN (Secure Unique NFC) message protection for high-security applications.
What operating systems are supported?
The Desktop USB NFC Encoder is compatible with Windows XP, Windows 7, Windows 8.1, Windows 10, Windows 11, Linux, and Android 4.0 and above. The USB HID interface ensures plug-and-play functionality without additional driver installation on most systems.
Can I export the UID list after reading multiple tags?
Yes, the encoder supports UID table export functionality. You can read multiple tags and export the collected UID data in various formats for integration with your access control or inventory management system.
What is the difference between USB HID and RS232 interface options?
USB HID (Human Interface Device) mode provides plug-and-play compatibility and appears as a keyboard input to your system, ideal for quick data entry. RS232 mode offers more advanced control and is preferred for integration with existing serial-based systems or custom software applications.
Do you provide SDK and technical support?
Yes, we provide comprehensive SDK, API documentation, and sample code for Windows, Linux, and Android platforms. Our technical support team is available to assist with integration, troubleshooting, and custom development requirements.
