1. HF (High Frequency) and UHF (Ultra High Frequency) RFID chips
UHF (Ultra High Frequency) RFID labels and HF (High Frequency) Chips are no longer strange to users and have become more and more popular in the market. In addition, there are still other types such as LF (low-frequency) or NFC (near field communication).
These lines of RFID chips are identified based on frequency range, so the way they work and the purpose of use will be different. So let’s analyze the outstanding features of the two lines RFID HF and UHF RFID Tag.
2. RFID Label – HF RFID System
HF RFID tags or HFID’s (High Frequency Identification) are the most popular form of RFDI technology today, with a frequency range of 3 to 30 MHz , used in a variety of applications. Near-range HFID requires the chip to pass or operate within close range (less than one meter) of a scanner or RFID reader.
3. UHF RFID Label – UHF RFID System
UHF RFID labels are a newly developed technology with frequencies ranging from 300 MHz to 3GHz used for tracking from afar or over a distance. This type of frequency supports writing as well as reading chips. For example, if a person holding a ticket passes through a checkpoint, an RFID antenna can transmit specific access instructions to their ticket or pass for the event they are attending. UHF is considered a “Supply Chain Frequency” with low cost while superior range and reading speed.
So, talking about the differences between HF and UHF RFID systems, let’s look at the analysis table below.
| RFID LABEL TYPE | ||
| HF (High Frequency) | UHF (Ultra High Frequency)< /td> | |
| Frequency range | 3 to 30 MHz | 300 MHz to 3GHz |
| Popular frequency | 13.56 MHz (NFC) | 860 to 960 Mhz (UFH Gen 2) |
| Relative costs | $$-$$$ | $ |
| Reading Range< /td> | ≤30cm | ≤100m |
| Benefits</ td> | Higher memory capacity, NFC tags can work as both reader and tag | Low cost, large reading range and fast reading speed |
| Popular apps | Animal tracking, car inventory | Inventory control, item tracking, supply chain monitoring and optimization |
UHF RFID labels are an optimal choice for long-range management
