- AAA Batteries: Open the battery compartment on the back of the device and insert 4 AAA batteries (not included), ensuring correct polarity.
- USB Power Supply: Connect the device to a computer or a USB power adapter using the provided USB data cable.
Press the power button to turn on the device. The display will light up.
3.2 Connecting to a Computer (for Decryption)
For decrypting certain 13.56MHz encrypted cards, the device must be connected to a computer.

Figure 3.2: Connection diagram illustrating the copier connected to a computer via USB, with a representation of the software interface. The USB cable connects the copier to a computer for advanced functions like decryption and software interaction.
- Connect the USB data cable from the copier to an available USB port on your computer.
- The device may require specific software for decryption. Refer to the manufacturer's website or included documentation for software installation instructions.
4. Operating Instructions
4.1 Reading a Card
- Turn on the device.
- Place the card or keyfob you wish to read on the card sensing area (located on the back of the device, refer to Figure 3.1).
- Press the READ button.
- The display will show the card number and type if successful.

4.2 Writing/Duplicating a Card
To duplicate a card, you must first read the source card, then write the data to a compatible writable card or keyfob.
- Follow the steps in Section 4.1 to read the source card. Ensure the card data is displayed on the screen.
- Remove the source card.
- Place a compatible writable card or keyfob (e.g., UID keychain, T5577 card) on the card sensing area.
- Press the WRITE button.
- The display will indicate if the writing process was successful.
Note: For successful writing, ensure the target card is a writable type (e.g., UID cards for 13.56MHz, T5577 for 125KHz). Standard read-only cards cannot be written to.
4.3 Decrypting Encrypted 13.56MHz Cards
The device can decrypt most 13.56MHz encrypted cards when connected to a computer.
- Connect the copier to your computer via the USB cable (refer to Section 3.2).
- Launch the dedicated decryption software on your computer.
- Follow the software's instructions to initiate the decryption process. This typically involves placing the encrypted card on the copier's sensing area and allowing the software to analyze and decrypt the data.
- Once decrypted, the software will guide you through writing the decrypted data to a new writable card.
Important: Decryption capabilities may vary depending on the encryption complexity and the specific software version. Not all encrypted cards can be decrypted.
4.4 Frequency Support
The copier supports reading and writing across a broad range of frequencies:
- 125KHz
- 250KHz
- 375KHz
- 500KHz
- 625KHz
- 750KHz
- 875KHz
- 1000KHz
- 13.56MHz
It is compatible with various card types including ISO 14443 A cards, EM cards, T5577 cards, Ntag 213/215/216, and others.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Avoid using liquid cleaners or abrasive materials.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Replacement: If using AAA batteries, replace all four batteries simultaneously when the low battery indicator appears on the display.
- Software Updates: Periodically check the manufacturer's website for any available software or firmware updates for enhanced functionality or compatibility.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted batteries; USB cable not connected properly. | Replace AAA batteries or ensure USB cable is securely connected to a power source. |
| Cannot read a card. | Card not placed correctly; card type not supported; card damaged. | Ensure the card is flat against the sensing area. Try another card. Verify card type compatibility. |
| Cannot write to a card. | Target card is not writable; data not read correctly from source card; target card damaged. | Ensure the target card is a compatible writable type (e.g., UID, T5577). Re-read the source card. Try a different writable card. |
| Decryption fails for 13.56MHz card. | Card encryption too complex; software not installed or updated; device not connected to PC. | Ensure the device is connected to a PC with the correct software. Update software. Note that some advanced encryption may not be supported. |
| Display is blank or unresponsive. | Power issue; device malfunction. | Check power supply. Try restarting the device. If the problem persists, contact customer support. |
