RFID Transponders, Tags

RFID transponder tags are compact devices that integrate both a receiver and a transmitter. These tags are specifically designed to communicate with radio frequency identification (RFID) readers, operating at specific frequencies associated with RFID technology. Here is a detailed description of the characteristics that define RFID transponder tags:

1. Style: RFID transponder tags come in various styles, each suited for different applications. The common styles include: Card: These tags resemble standard plastic cards, making them suitable for applications such as access control or identification cards. Coin: Coin-shaped tags are typically used in applications where a small form factor is required, such as inventory management or asset tracking. Encapsulated: Encapsulated tags are designed to be protected within a durable casing, providing resistance against environmental factors like moisture or physical impact. Glass encapsulated: These tags are encased in glass material, offering enhanced durability and resistance to harsh environments. Inlay: Inlay tags consist of a thin, flexible substrate with an embedded RFID chip and antenna, allowing for easy integration into various objects or surfaces. Key fob: Key fob tags are compact and often attached to keychains, providing a convenient way to carry and use the RFID tag. Nail: Nail tags are designed to be easily embedded into objects like wooden pallets or assets, enabling efficient tracking and management. Wristband: Wristband tags are worn on the wrist like a bracelet and are commonly used in applications such as event access control or healthcare.

2. Technology: RFID transponder tags employ different technologies to enable communication with RFID readers. This can include passive, active, or semi-passive (battery-assisted) technologies, depending on the specific requirements of the application.

3. Frequency: RFID transponder tags operate at specific frequencies that determine their compatibility with RFID readers. Frequencies can range from 100 kHz to 960 MHz, covering various RFID standards and applications.

4. Memory type: RFID transponder tags have onboard memory that stores data related to the tagged object or item. The memory can be categorized as:

Read-only: Tags with read-only memory contain pre-programmed data that cannot be modified. Writable: Tags with writable memory allow for data to be written and updated as required, providing flexibility in applications such as inventory management or supply chain tracking.

RFID transponder tags serve as the key component in RFID systems, enabling wireless communication with RFID readers. Their specific style, technology, frequency compatibility, memory type, and writability contribute to their versatility and suitability for various applications ranging from access control to asset tracking.
