2. Key Features
The CatXQ Smart Ring integrates advanced technology to offer a range of functionalities:
2.1 IC and ID Card Simulation
The built-in IC and ID modules allow for the simultaneous simulation of up to four smart cards. This includes common card types such as Access Cards, Elevator Cards, Time Cards, Parking Cards, Membership Cards, and Shopping Cards. The read-write process for these modules is identical to that of ordinary physical cards. Simply place the ring within the sensing range of the corresponding dedicated read-write device for authorization or copying.

2.2 NFC Module Functions
The integrated NFC module provides a suite of cloud-based services:
- Virtual Call: Initiate a virtual call to simulate receiving a phone call.
- Scene Notification: Trigger notifications based on specific scenarios or locations.
- Business Card Sharing: Share your digital business card instantly.
- Memo Sharing: Share notes or memos with compatible devices.



2.3 Durability
The smart ring is designed for everyday wear, featuring IP68-grade waterproof and dustproof capabilities. It is also anti-abrasive, ensuring no fading or deforming over time, making it suitable for various occasions.
3. Setup Guide
To begin using your CatXQ Smart Ring, follow these setup steps:
3.1 NFC Function Activation
Ensure NFC is enabled on your mobile device. For Android users, navigate to your phone's settings and turn on the NFC function. For iPhone users, confirm your phone model supports NFC (iPhone XS, XR, XS Max, 11 series, 12 series, 13 series, and newer models launched after September 2018 support NFC functionality).
3.2 App Installation and Device Pairing
- Ensure your mobile phone has WhatsApp installed and you are logged in.
- Scan the QR code provided in the operating manual (or on the product packaging) to automatically skip to WhatsApp.
- Click to send the preset chat content. This will provide a link to your device homepage (e.g.,
https://i.JAKCOM.com/User/Setting). - Click the link to enter your device homepage.
- Click the "Add Device" button.
- Input the activation code corresponding to the NFC module, found on the product packaging or manual.
- Once added, click your device name (e.g., JAKCOM_R4_05) to enter the function setting menu.
4. Operation
4.1 Using IC/ID Modules
To use the simulated IC/ID cards, simply move the ring's IC/ID module close to the sensing range of the reading device (e.g., a door access reader). The read-write process is the same as using an ordinary physical card.
4.2 Using NFC Functions
To activate NFC functions, touch the NFC sensing area of your cellphone with the smart ring. The NFC induction area is generally located in the non-metallic area on the back of your cellphone. When prompted to select a default app to open, please select "Web Browser" for optimal functionality.

5. Maintenance
The CatXQ Smart Ring is designed for durability and requires minimal maintenance:
- Cleaning: Wipe the ring with a soft, damp cloth to remove dirt or smudges. Avoid abrasive cleaners.
- Water and Dust Resistance: The ring has an IP68 rating, meaning it is highly resistant to water and dust. However, prolonged submersion in deep water or exposure to high-pressure water jets should be avoided.
- Storage: Store the ring in its protective case when not in use to prevent scratches and maintain its finish.
- Avoid Extreme Conditions: While durable, avoid exposing the ring to extreme temperatures or harsh chemicals, which could potentially damage the ceramic material or internal components.
6. Troubleshooting

- Sensing Area: Make sure you are touching the correct NFC sensing area on your phone (typically the non-metallic area on the back).
- Proper Placement: For IC/ID card simulation, ensure the ring is placed directly within the sensing range of the reader.
6.2 App/Setup Issues
- WhatsApp Installation: Confirm WhatsApp is installed and you are logged in on your mobile phone.
- Activation Code: Double-check that the activation code entered during device pairing is correct.
