6 Factors that Affect RFID Read Range*

Key Takeaways: RFID read range is influenced by several factors, including antenna gain, antenna polarization, and RFID tag information. Antenna polarization plays a key role, with linear polarized antennas exhibiting a longer range when tags are aligned accordingly. Tag-related factors, such as size, orientation, angle, and placement, also impact the read range due to the interaction between the tag and the antenna.

RFID Antenna Cables: Getting the Highest Performance Possible

Key Takeaways: The importance of antenna cable selection in RFID systems is essential. Factors such as cable length, desired read range, and antenna gain are key considerations. By choosing the right cable and considering these factors, there is minimized power loss and increased optimization of your RFID system performance.

Which Applications Need High Memory RFID Tags?

Key Takeaways: Determining the need for high memory RFID tags may not be based on specific applications, but rather on the availability of reliable database access. If an application can access a database to retrieve relevant information about a tagged object, a unique ID on the tag is sufficient. However, if database access is not feasible and data needs to be stored on the tag itself, high memory RFID tags become necessary.

Pitch, Yaw, and Roll: Positioning RFID Tags

Key Takeaways: Pitch refers to the 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. Having a clear understanding of how these movements impact the readability of an RFID tag is crucial for optimal performance in any RFID system. Conducting tests is essential to assess the extent to which pitch, yaw, and roll affect your specific application and to identify strategies for minimizing any adverse effects.

Five Ways to Attach RFID Tags

Key Takeaways: Film Adhesive is used for most tags and standard applications, while foam adhesive is typically used with more rugged tags and in applications requiring a stronger adhesive method. Epoxy is used to cover embedded tags where you need the strongest adhesion possible. Screws/rivets are used in conjunction with durable tabs. Lastly, wire or cable ties are used where any of the above options are not feasible.

Locking Memory on Gen 2 RFID Tags

Key Takeaways: An EPC GEN 2 tag possesses two distinct passwords: an access password and a kill password. Both passwords consist of 32 bits and are stored in the reserved bank of the tag's memory. Upon being singulated, the tag assumes one of two states: secure (if the access password is all zeros) or open (if a non-zero access password has been programmed into the tag). It is important to understand that assigning a non-zero access password alone does not hinder anyone with a GEN 2 RFID reader from reading or modifying data on the tag.
