With RFID experiencing quick growth and adoption across a wide range of applications within Manufacturing, Transportation & Logistics, and Healthcare. RFID labels represent a key component in the success of any RFID solution.
What are the components of an RFID Label?
a.) Chip – This makes up an inlay along with the antenna. Microchips come with storage in the form of memory and this memory can store 3 types of information:
1) Data about the asset being tracked – This information is stored in the Electronic Power Code (EPC) memory bank. Common sizes for EPC are 96 and 128 bits but memory sizes can vary based on the microchip used
2) Data about the tag itself, such as the manufacturer
3) Data that makes the tag work, such as access and kill passwords
b.) Antenna – This makes up an inlay along with the microchip. In essence, an antenna is what allows the RFID tag to communicate with the RFID reader. The antenna receives signals from an RFID reader and sends data back to the reader. Antennas come in many shapes and sizes with the design being an important factor as it affects how the data is transmitted and read. Antennas are often designed for specific purposes because one size does not fit all, and different RFID applications require different sizes and shapes of the antenna. Optimal antenna design will depend on many factors, including the microchip in use, the material on which the inlay is applied, and the environment in which it will be used.
c.) Inlay – Microchip connected to an antenna on a flexible substrate
d.) Carrier - The carrier of an RFID tag is what contains the inlay in whatever format is most appropriate for the application and item being tagged. Carriers can be labels or non-adhesive tags, that can vary in size and rigidity. At Zebra, we offer over 100 pre-tested materials that can be used as the carrier for your RIFD tag, providing you with many options to meet the specific requirements of your application.
