4. Operating Instructions
The NS106 supports reading, writing, duplicating, decoding, and cracking various RFID and NFC cards. Ensure the software is running before proceeding.
4.1. Reading and Writing Ordinary 125KHz RFID Cards (EM4100, TK4100, EM4305, T5577)
- Read Original Card: Place the 125KHz original card (e.g., EM4100/TK4100) onto the card reading area of the NS106. In the software, click the "Read" button. The software will scan and display the card number. Remove the original card.
- Prepare Writable Card: Place a writable T5577 or EM4305 (125KHz writable chip) card or key fob onto the card reading area.
- Write Data: In the software, click the "Write" button. The data from the original card will be written to the new writable card. A success message will confirm the operation.

4.2. Reading and Writing 13.56MHz IC Cards (UID, FUID, CUID, UFUID, Half/Full Encryption)
- Read Original Card: Place the 13.56MHz original card (e.g., Mifare Classic) onto the card reading area. In the software, click "Read" or "Start decoding" (for encrypted cards). The software will attempt to read and decode the card data.
- Prepare Writable Card: Remove the original card. Place a writable UID, FUID, CUID, or UFUID (13.56MHz writable chip) card or key fob onto the card reading area.
- Write Data: In the software, click "Write Type-A" or "Write EMID" depending on the card type and desired operation. The decoded data will be written to the new writable card.

4.3. Duplicating Encrypted Cards (as shown in Video 1)
For encrypted 13.56MHz cards, the process involves decoding the original card before writing to a new one.
- Place Encrypted Card: Put the encrypted 13.56MHz card on the reader.
- Start Decoding: In the software, click "Start decoding". The software will go through various sectors to crack the encryption. This process may take some time.
- Decoding Success: Once decoding is successful, the software will indicate "Successful card reading. Auth with all sectors succeeded."
- Prepare Writable Fob: Remove the encrypted card and place a writable 13.56MHz UID key fob on the reader.
- Write Decoded Data: Click "Write Type-A" in the software. The decoded data will be transferred to the writable key fob.

6. Troubleshooting
If you encounter issues with your YiToo NS106, try the following troubleshooting steps:
- Device Not Recognized: Ensure the USB cable is securely connected to both the device and your computer. Try a different USB port or cable.
- Software Not Found/Launching: Verify that the device is properly connected. If the software doesn't appear automatically, manually navigate to the device's drive (usually a removable disk) and launch the executable. If the file is missing or corrupted, download it from the official link provided in the Setup section.
- Card Not Reading: Ensure the card is placed correctly on the reading area. Check that the card type is supported by the device (125KHz ID or 13.56MHz IC). For encrypted cards, ensure you are using the "Start decoding" function.
- Writing Failure: Confirm that you are using a writable card/fob (e.g., T5577/EM4305 for 125KHz, UID/FUID/CUID/UFUID for 13.56MHz). Ensure the original card was successfully read/decoded before attempting to write.
- LED Indicator Issues: The LED should be red in standby and green during card reading. If it's off or behaving unexpectedly, check the USB connection and power supply from your computer.

Figure 12: LED indicator status: Red for standby, Green for card reading.
