5. 설정
The Whadda WPI417 RFID cards are passive devices and do not require any initial setup or power. They are ready for use upon receipt. Integration involves connecting them with a compatible 13.56 MHz RFID reader/writer and a host system (e.g., microcontroller, computer) for reading and writing data to the card's EEPROM memory. Refer to the documentation of your specific RFID reader and development environment for detailed integration instructions.
6. 운영
To operate the RFID cards, bring a card within the identification distance (0-5 cm) of a compatible 13.56 MHz RFID reader. The reader will then be able to communicate with the card. Depending on your application, you can perform the following operations:
- 데이터 읽기: The reader can retrieve data stored in the card's 1K Byte EEPROM memory.
- 데이터 쓰기: Data can be written to the card's EEPROM memory, up to 100,000 re-writes.
- 신분증: The unique identifier of the card can be read for authentication or tracking purposes.
Ensure your RFID reader and software are configured correctly for 13.56 MHz operation and the specific protocol used by these cards (e.g., ISO/IEC 14443 Type A).
7. 유지관리
The Whadda WPI417 RFID cards require minimal maintenance. Follow these guidelines to ensure their longevity:
- Clean cards with a soft, dry cloth. Avoid abrasive cleaners or solvents.
- Store cards in a cool, dry place, away from direct sunlight and extreme temperatures.
- Avoid placing heavy objects on the cards to prevent bending or cracking.
- Do not puncture or scratch the card surface, as this may damage the internal antenna or chip.
8. 문제 해결
- 카드가 감지되지 않음: Ensure the card is within the reader's identification distance (0-5 cm). Verify the reader is powered on and functioning correctly. Check for strong electromagnetic interference in the vicinity.
- Read/Write errors: Confirm the RFID reader is compatible with 13.56 MHz passive RFID cards and the correct communication protocol. Ensure the card is held steadily within the reader's field during operation.
- Intermittent detection: This may be caused by environmental interference or a weak reader signal. Try moving the reader or card to a different location.
