Ideal Equipment Performance

Key Points: The selection of antenna cables is critical in an RFID system. Factors such as cable length, desired read range, and antenna gain are key considerations. By choosing the appropriate cable and taking these factors into account, you can minimize power loss and optimize the overall performance of your RFID system.

Key Points: Determining the need for high-memory RFID tags may depend less on the specific application and more on the availability of reliable database access. If an application can access a database to retrieve information about the tagged item, then a unique ID stored on the tag is usually sufficient. However, if database access is not feasible and data must be stored directly on the tag, then high-memory RFID tags are required.

Key Points: Pitch refers to rotation of the tag along the x-axis, yaw refers to rotation along the y-axis, and roll refers to rotation along the z-axis. Clearly understanding how these movements affect RFID tag readability is critical for optimizing the performance of any RFID system. Testing is essential to assess the impact of pitch, yaw, and roll on a specific application and to develop strategies to minimize negative effects.

Key Points: Film adhesives are used for most tags and standard applications, while foam adhesives are typically employed for more robust tags and applications requiring stronger bonding. Epoxy is used to cover embedded tags where maximum adhesion is needed. Screws or rivets are used with durable cards. Finally, when none of the above methods are feasible, wire or cable ties can be used.
