3. Setup and Programming
These RFID cards are designed to be integrated with existing 125KHz access control systems. The setup process primarily involves programming the cards with your specific access control reader/writer.
Programming Instructions:
- Acquire a Compatible Reader/Writer: Ensure you have a 125KHz RFID card reader/writer device. This device is necessary to read the unique ID of the cards and, if supported by your system, to write specific data to them.
- Refer to Your System's Manual: The exact programming steps will depend on your specific access control system or RFID reader/writer. Consult the instruction manual provided with your access control system for detailed programming procedures.
- Enroll Cards: Typically, you will place an RFID card on the reader/writer, and the device will either read its unique identifier or allow you to write new data to it. Follow your system's prompts to enroll each card into your access control database.
- Test Functionality: After programming, test each card with your access control system to ensure it grants access as intended.
Note: While these cards are described as "readable" and having an "erasable life," their specific writability features depend on the capabilities of your 125KHz RFID reader/writer and access control system. Some systems may only utilize the pre-programmed unique ID of the card.
4. Operating the Access Cards
Once programmed, using the Sonew 125Khz RFID Access Cards is straightforward. They operate on proximity technology, requiring no physical contact with the reader.
Usage Steps:
- Approach the Reader: Hold the RFID access card within the reading range (typically 5-10 cm) of the compatible 125KHz access control reader.
- Wait for Confirmation: The reader will typically provide an audible beep or a visual indicator (e.g., an LED light changing color) to confirm that the card has been successfully read and access has been granted or denied.
- Enter/Exit: If access is granted, proceed through the controlled entry point.

5. Maintenance and Care
To ensure the longevity and reliable performance of your RFID access cards, follow these simple maintenance guidelines:
- Keep Clean: Wipe the cards periodically with a soft, dry cloth to remove dust and grime. Avoid abrasive cleaners.
- Avoid Extreme Conditions: Do not expose the cards to extreme temperatures (outside -20°C to 55°C), direct sunlight for prolonged periods, or high humidity.
- Prevent Physical Damage: Avoid bending, scratching, or puncturing the cards, as this can damage the internal antenna or chip.
- Store Properly: When not in use, store cards in a clean, dry place, away from strong magnetic fields or other RFID devices that could interfere with them.
6. Troubleshooting
If you encounter issues with your Sonew 125Khz RFID Access Cards, consider the following troubleshooting steps:
- Card Not Reading:
- Ensure the card is within the reader's specified reading distance (5-10 cm).
- Verify that the reader is powered on and functioning correctly.
- Confirm the card has been properly programmed and enrolled in your access control system.
- Check for any physical damage to the card.
- Access Denied:
- Confirm the card is correctly programmed for the specific access point.
- Check the access control system's logs for reasons for denial (e.g., invalid card, expired access).
- Ensure the card is presented correctly to the reader.
- Inconsistent Reading:
- Avoid holding multiple RFID cards together when presenting to a reader, as this can cause interference.
- Ensure there are no strong electromagnetic fields near the reader or card during use.
If problems persist, consult the manual for your specific access control system or contact the system administrator/installer.
