RFID UHF Inlays and Tags

What is a UHF RFID tag?

When we speak about RFID technology, we refer to the acronym of Radiofrequency Identification. As can be sensed by its name, the fundamental purpose of the implementation of RFID systems is the traceability of objects or people by the individual identification of each subject. RFID systems are composed of an RFID reader, an RFID tag and a database.

RFID systems communicate and operate based on different standards and protocols. In addition, they work at different frequencies and, depending on this frequency, we can divide the RFID systems into three: LF, HF and UHF.

The low frequency (LF RFID) covers from 125 KHz to 134 KHz and offers a reading range of 10 cm. The high frequency (HF RFID) generally operates at 13.56MHz and has reading ranges of 10cm to 1m. Finally, the Ultra High Frequency (UHF RFID) covers 433MHz and between 860MHz and 960MHz. The reading range of the UHF systems can be up to 12 meters, and has a faster data transfer rate than the LF or the HF. You have more information about this in our article about how to understand a datasheet.

UHF RFID tags are the right choice when we want a quick reading of numerous items simultaneously at a distance of no more than 12 m and at a very low cost per RFID tag.
