What are RFID tags? Comparing ultra-high-frequency (UHF) vs. high-frequency (HF) vs. near field communication (NFC) vs. low-frequency (LF) RFID tag types. An explanation of the difference between active, passive and .Learn the fundamentals of RFID technology and how it differs by frequency. Compare the read range, speed, sensitivity, and applications of low, high, and ultra-high frequency RFID tags.
What are RFID tags? Comparing ultra-high-frequency (UHF) vs. high-frequency (HF) vs. near field communication (NFC) vs. low-frequency (LF) RFID tag types. An explanation of the difference between active, passive and semi-passive RFID tags.In 2017, UHF RFID tags cost approximately $.05 to $.15 per tag, whereas HF tags range from $.50 to .00 per tag. Using a UHF RFID system eliminates the need for manual processes, thus increasing inventory visibility and automating workflows.
When choosing an RFID tag, one important but not-often-thought-of decision to make is the frequency of the tag, such as LF, HF or UHF. Which do you choose? low frequency (LF, 30 KHz to 300 kHz; typically LF systems work at 125 KHz)The two RFID frequency bands, HF vs UHF, have obvious differences in terms of application areas, technical characteristics and advantages. When enterprises choose to use which RFID frequency band, should fully consider their own needs and the performance and cost trade-offs.
Low Frequency RFID & High Frequency RFID have 8 key differences that set them apart - the actual frequency range , data rates, write capabilities, environmental concerns, read range, tag formats, RFID applications, RFID hardware. The two main types of UHF RFID tags are Labels/Inlays and Hard Tags. Labels/Inlays are thin, flexible, and cost-effective, while Hard Tags are more durable, come in various shapes and sizes, and are suitable for harsh environments.
The primary difference between RFID HF and UHF lies in the frequency bands they operate in. RFID HF operates in the High-Frequency range of 13.56 MHz, while RFID UHF operates in the Ultra-High Frequency range of 860-960 MHz.
High-frequency RF signals are more able to penetrate liquids because the longer wavelengths of HF systems are less susceptible to absorption. UHF's shorter wavelengths are more susceptible to absorption by liquids. In practical applications, HF tags are better suited for tagging water- or liquid-bearing containers.UHF RFID frequency also has an extremely high tag reading speed, which can identify hundreds of tags in a short time, which is particularly important in fast-moving logistics environments. However, metal and liquid environments easily interfere with UHF RFID signals, which may reduce reading distance and reliability.Summary. There are particular needs where each type of RFID card is a better fit for the specific application. However, UHF tags are the most popular for new developments in the RFID market. A more extended range of UHF cards makes it suitable for a variety of industrial applications. What are RFID tags?

To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). When. * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output. * will show the type, and the NUID if a new card has been detected. Note: you may see "Timeout in communication" messages.
