RFID Technology

Definition

RFID technology, or Radio Frequency Identification technology, is a wireless communication system that uses electromagnetic fields to automatically identify and track tags attached to objects. This technology can transmit data between a reader and a tag, enabling various applications such as inventory management, supply chain tracking, and even access control. The flexibility of RFID tags allows them to be embedded in flexible printed circuits, enhancing their integration into various devices and systems.

5 Must Know Facts For Your Next Test

1. RFID technology operates using two main components: an RFID reader that emits radio waves and an RFID tag that responds with its stored data when activated.
2. Flexible printed circuits allow RFID tags to be made thinner and lighter, making them suitable for applications in wearables and other compact devices.
3. RFID tags can be passive, active, or semi-passive, with passive tags being the most common due to their low cost and maintenance-free nature.
4. The integration of RFID technology with flexible printed circuits can enhance the durability and performance of devices used in harsh environments.
5. RFID systems can operate over various distances, from a few centimeters for NFC to several meters for more robust RFID systems, depending on the type of tag and reader used.
