How far can a UHF RFID reader read?

The range of a UHF (Ultra High Frequency) RFID reader can vary depending on several factors including the power output of the reader, the sensitivity of the RFID tags being used, environmental conditions, and potential interference. However, in general, UHF RFID readers can typically read tags at distances ranging from a few inches to several meters.

Under optimal conditions, some UHF RFID readers are capable of reading tags from distances of up to 30 feet or more. However, in real-world applications, factors such as tag orientation, presence of metal or liquids, and interference from other electronic devices can significantly reduce the effective read range.

It's important to consider these factors when designing RFID systems to ensure that the desired read range is achieved for the specific application. Additionally, conducting thorough testing in the intended environment can help determine the actual read range that can be expected.
