UFID RFID Tag: Difference And Advantages

Introduction To UHF RFID Tags

Ultra-High Frequency, UHF, is becoming more famous for solving complex RFID tag problems and meeting business wants across several industries. However, questions surrounding High Frequency (HF) and Ultra High Frequency (UHF) remain. Several still wonder either UHF or HF tags are the perfect solution for meeting trade goals. To understand why it is the case, one must first understand what UHF RFID Technology is, the differences between HF and UHF materials, and applications where you deploy these tags successfully.

UHF RFID Tags Vs. HF RFID Tags

People view HF up until now as a more reliable and established technology. However, modern developments set that UHF RFID products are equally reliable and often provide better performance across various applications. To know why that is, we first understand the difference between HF tags and UHF Tags.

HF and UHF tag products operate at various frequencies. The maximum read range for HF RFID tags is 13.56 MHz, and the maximum read range is around 3 feet. However, UHF RFID tag manufacturer operates between 858 to 930 MHz frequency band and can have a read range of about 30 feet; there are tags with a more extended read range, about 30ft is an average.

People consider HF Tags more “mature” tags, as they have been around for longer. While UHF RFID tag manufacturer provides dominant technology for supply chain applications, people believe that because of their “maturity” and a short read range, HF RFID tags are a better choice for item-level or near-field applications. However, it has become apparent that UHF tags are equally as reliable as HF tags and often can provide better performance in past years. Moreover, UHF products do not require near-field RFID tags to be read at a close range. Ultra High-Frequency tags can read both at close and long ranges: around 30 ft. tag can also read from an inch away. Due to their versatile read range, UHF RFID tags can enhance various applications and processes at different read distances. UHF RFID products are perfect for work-in-process applications comprising inventory tracking, anti-counterfeit applications, identification applications, and more. As these RFID tags can provide the range and coverage users want, UHF products are ideal for applications where a “universal” RFID tag is necessary or a tag that can read at both long and short distances.

Moreover, HF RFID tags are not an option where a more extended read range is essential. Therefore, it is necessary to consider future applications and extensions of RFID uses when planning on applying an HF RFID System.

Advantages Of UHF Tag Technology

Several benefits to using Ultra Hight Frequency tag Technology, the two most relevant are price and performance. The speed at which this technology can read and the distance over which UHF products can read are usually higher when compared to the HF tag. Additionally, because of mandates to their supplier to use UHF products for their supply chain tracking, from giants like Wal-Mart and Gillette, people believe that UHF products are cheaper. The idea is that as UHF RFID production volume increases, the cost may decrease.
