Wooden cards are combined with RFID (Radio Frequency Identification) technology by embedding an RFID chip into the wooden card. This integration not only preserves the aesthetic and eco-friendly qualities of wooden cards but also adds the convenience of modern technology. Below is a detailed explanation of how wooden cards are combined with RFID technology:
1. Embedding the RFID Chip
- Chip Selection: RFID chips are typically very small, only a few millimeters thick, and can be easily embedded into wooden cards without affecting their appearance.
- Card Design: During the production of wooden cards, a dedicated space (usually a small groove or layer) is reserved for placing the RFID chip.
- Embedding Process: The RFID chip is placed within the layered structure of the wooden card and secured with eco-friendly glue or resin to ensure it does not shift or fall out.
2. Antenna Integration
- RFID systems require an antenna to receive and transmit signals. The antenna, usually made of copper or aluminum, is coiled and connected to the RFID chip.
- In wooden cards, the antenna can be embedded around the chip or placed as a thin layer within the card’s structure.
- The antenna design ensures stable signal transmission while maintaining the card’s aesthetics and durability.
3. Card Structure
- Wooden cards typically adopt a multi-layer design, such as:
- Outer Layer: Natural wood or wood composite, providing aesthetics and texture.
- Middle Layer: The RFID chip and antenna are embedded here to ensure signal transmission.
- Base Layer: Another layer of wood or protective material to enhance the card’s durability.
- This layered structure protects the RFID components while preserving the natural appearance of the wooden card.
4. Signal Transmission and Functionality
- When the wooden card is brought near an RFID reader, the electromagnetic waves emitted by the reader activate the RFID chip in the card.
- The chip receives energy through the antenna and transmits stored data (such as room numbers or access permissions) to the reader.
- The entire process is contactless, requiring only proximity to the reader for recognition, offering a seamless and convenient user experience.
5. Technical Compatibility
- The RFID technology in wooden cards can be seamlessly integrated with hotel door lock systems, membership management systems, or other smart devices.
- Common RFID frequencies include low-frequency (LF), high-frequency (HF), and ultra-high-frequency (UHF). Wooden cards typically use high-frequency (13.56 MHz) RFID technology, as it offers stable and secure short-range recognition.
6. Design and Aesthetics
- The design of wooden cards can completely conceal the RFID components, maintaining their natural appearance.
- Laser engraving or embossing techniques can be used to add hotel logos, room numbers, or decorative patterns to the card’s surface, further enhancing its visual appeal.
7. Durability and Protection
- To ensure the durability of the RFID chip and antenna, wooden cards are often treated to be water-resistant and scratch-proof.
- The use of eco-friendly resin or protective coatings extends the card’s lifespan while safeguarding the internal electronic components.
8. Eco-Friendliness and Sustainability
- Wooden cards themselves are an eco-friendly material, and the long lifespan of RFID chips reduces the waste associated with frequent replacement of traditional plastic cards.
- By using sustainably sourced wood and recyclable RFID components, wooden cards further emphasize environmental responsibility.
The combination of wooden cards and RFID technology is achieved by embedding the RFID chip and antenna into the layered structure of the wooden card. This design not only retains the natural beauty and eco-friendly qualities of wooden cards but also incorporates the convenience of modern technology. Wooden RFID cards are suitable for hotels, membership systems, access control, and other applications, offering users a premium, eco-friendly, and intelligent experience.
