RFID Low Frequency VS. High Frequency : what is the different

RFID Low Frequency VS. High Frequency

In this article, you are going to learn about the RFID Technology‘s two approaches when defining the extent of the product’s application- the Low Frequency (LF) and the High Frequency (HF). As to why the LF and HF classifications of RFID products are essential for you as a potential customer or an avid reader of technological advancements,

 

let’s further discuss and differentiate the RFID Low Frequency vs High Frequency. In the paragraphs below, you will know who will emerge victorious in the battle between the RFID LF vs HF.

RFID LF vs HF: Their Definitions

I.RFID LF vs HF Their Definitions

By definition, the Lower Frequency or LF RFID is a type of RFID that operates within the frequency of 125 kHz and has a slower rate of data reading. On the other hand, the High Frequency or HF RFID is a type of RFID that operates within the frequency of 13.56 MHz. Unlike the LF types of RFID, HF RFID has a faster rate of data reading.

Aside from the LF and HF, there is also the Ultra-High Frequency or UHF RFID. This type of RFID can be considered by some manufacturers as different from HF. However, the UHF is one of the classifications of an HF RFID. It operates within 900-915 MHz but with the fastest rate of data reading compared to the HF.

Although UHF can be considered as another type of RFID frequency, it shares almost similar features to the HF. In other words, the UHF RFID are refined feature of the HF.

Typically, you would think that in the comparison of RFID Low Frequency vs High Frequency, the RFID High Frequency would be the best choice for you. Let’s get to know more about them. Comparatively, they differ in what they can offer, but it depends on your needs as a customer or as an organization.

 

RFID LF vs HF: The Difference?

RFID LF vs HF The Difference

The comparison between the RFID Low Frequency vs. High Frequency will continue by defining their differences.

 

The differences between the LF and HF vary in their usage, proximity of detection, and the tendency of electromagnetic interference.

The LF RFID has a higher electromagnetic wavelength. This means that it has minimal susceptibility to electromagnetic interference. This is the reason why the LF RFID has a slower rate of data reading.

The HF RFID has a medium electromagnetic wavelength. This means that the HF RFID can be on medium to high susceptibility to electromagnetic interference. This is why the HF RFID has a higher rate of data reading. As the rate goes higher, the tendency to be susceptible to electromagnetic interference will also soar as well.

Aside from the differences mentioned above, the LF RFID has limited features and uses available for the users to take advantage of. However, the HF RFID has many features. However, not all of the RFID manufacturers can produce HF RFID because of their expensive cost and lack of facilities to meet such demands.

 Write capabilities:

Write capabilities

When comparing the RFID Low Frequency vs. High Frequency, the write capabilities of these two types of RFIDs are quite different.

When we say RFIDs that are read-only data, these are typically RFID products that are in Low Frequency. This means that the RFIDs with read-only write capabilities have simple pre-encoded tags with memory banks embedded in their data.

Some RFIDs have read-and-write data, these are typically the RFID products that are in High Frequency. The RFIDs with read-and-write data can be overwritten hundreds of times. However, they can be used on advanced monitoring systems and those industries that utilize computer database systems.

 

 Work well in different environments

The contrast of the RFID LF vs. HF must also manifest in how it works in different environments. The RFID LF vs. HF has different efficiency when it comes to the environment it was installed or used.

Unlike the UHF RFIDs, the LF and HF do not have complications when used on metals, liquids, or other challenging work environments. The LF and HF RFIDs can work well in a challenging environment, but to a different extent.

The LF and HF RFIDs can work in a moist environment. However, the LF RFIDs can still be read even if the tag is near your skin, on the metal surface, and under the water. The LF is highly tolerant to challenging environments, unlike the HF RFIDs.

The HF RFIDs can work near the water and metal surfaces on a medium tolerance. However, it cannot work on all types of metal surfaces and it cannot also function under water. The LF RFIDs can only function in challenging environments, but they can only depend on their tags.

 

Reading Range

Reading Range

When identifying the contrast between the RFID Low Frequency vs. High Frequency, the reading ranges of these two RFIDs are completely different. Before purchasing any of these RFIDs, you must measure out their following reading ranges.

The LF and HF RFIDs can be read in short ranges. It means that it can be read with up to 3 feet. Typically, the LF RFIDs can be detected with up to 1 foot. However, the HF RFIDs can be detected with up to 3 feet.

When near the RFID scanners, the RFID LFs can be read at a distance of six inches, while the RFID HFs can be read on up to a ruler distance.

Although both can be read on a short range, the LF operates from 30-300 KHz with a slower data reading rate. The RFID HFs can operate within 3-30 MHz and have a quicker data reading rate, but it is sensitive to electromagnetic noise.

 

Vary regarding tag form

Vary regarding tag form

Aside from knowing their distinct features, you also need to identify the products that belong to the RFID LF and HF ,so you can better understand why certain applications are only present to RFID LFs or RFID HFs, respectively.

When we say RFID LFs, these are typically the RFID products that are specifically sold in soft or liquid materials. It means that they could go well on the mentioned substances.

On the other hand, RFID HFs are typically RFID products that are descriptively made from hard and flexible materials.

 

Different RFID Hardware Requirements

 

There are also different RFID hardware requirements that individuals or industries alike must have so it can be utilized on its full features.

To utilize RFID LFs, individuals or industries must have handheld RFID readers to make the transaction happen.

However, the RFID HFs can make a transaction flexibly by using the doorway-type RFID Scanner, USB-type RFID scanner, and even the NFC reader of your smartphones.

RFID LF vs HF: How it Operates

The comparison of RFID Low Frequency vs High Frequency does not just stop on how we should define or differentiate them. You must also evaluate how these two RFID types work. These two types of RFIDs can be classified into three: Active RFID, Passive RFID, and Semi Passive RFID.

 

Active RFID.

The RFID Low Frequency vs High Frequency must be identified whether the RFID device was battery-powered or not.In this case, the active RFID are those RFID products that have batteries within. It means that it will function through its battery that receives the signal, store your data, and activate the transaction.

 

Passive RFID.

The RFID Low Frequency vs High Frequency can also be identified through the visibility of the battery. Passive RFID are those RFID products that do not need the battery to function. It means that it functions by storing and protecting your data. Although it does not have a battery, the Passive RFIDs tend to have a slower transaction process.

 

Semi-Passive RFID.

The RFID Frequency vs High Frequency can be identified as the availability of a battery that possesses a significant role in the contactless transaction. Semi-Passive RFID are those RFID products that work without batteries but have a faster transaction rate. It means that the Semi-Passive RFIDs do work with many functions, not just on storing your identity alone.
