The Ultimate Guide to Choosing the Best RFID Animal Tag Reader

Animal tag readers, also known as pet microchips, use RFID technology for identification. RFID stands for Radio Frequency Identification (RFID). The technology helps in communicating critical information. Many businesses worldwide use RFID to track their assets, especially animal husbandry. But the question is this: how do you choose the best RFID animal tag reader? What are the quantities that you should check and the factors that you must consider? Here is an article mentioning the factors that influence the choice of the best animal RFID reader.

What Is an Animal RFID Tag Reader?

Let’s understand their meaning before we learn how to choose an animal tag reader. RFID animal tag reader is used for animal identification and management. Each reader comprises two components: smart label and reader.

The labels have an integrated process and antenna. It uses frequency waves to send a signal to the reader. Tags are attached to the animal and thus send continuous data signals to the receiver. As the reader gets information, software translates it into user-friendly language. Thus, the manager or owner knows the exact location and position of their cattle and animals.

Types of RFID Animal Tag Readers

There are two types of RFID tag readers available in the market. Both have their unique set of properties. And you should select the one according to your need:

Passive RFID Tags

Passive animal tags are cheaper than others and don’t have an internal power source. Thus, they are ideal for close-range scanning.

Active RFID Tags

The cost of active tags is higher due to the built-in battery. These animal tags have more features than others. Thus, they are suitable for long-range tracking and monitoring.

Uses of RFID Animal Tag Reader

The RFID tag reader is used for livestock management. It helps farmers track their animals’ health and breeding. In addition, it has other uses.

  • Veterinarians use RFID tag readers to maintain accurate records. Readers allow them to scan the information of their animal patients easily.
  • Further, even pet owners can trace their pets’ movements. If, by chance, their pets run away, you can quickly spot their present location.
  • If you are into wildlife conservation or research, you can also use an RFID animal tag. The reader will help you check animal populations and study their behaviors.

How to Choose the Best RFID Animal Tag Reader?

When choosing the best RFID animal tag reader, you should consider all the necessities, such as quality, durability, frequency range, etc.

Before finalizing the animal RFID reader, follow these steps:

  • Identify your primary requirements. Why are you looking for RFID animal tag readers? Whether for managing the livestock, farm management, etc. Also, decide what kind of environment you will be using the RFID reader.
  • Ensure that the RFID reader you are investing in is compatible with the RFID tags you are using. This will prevent extra costs.
  • Choose a reputed RFID reader manufacturer with enough data storage capacity and convenient transfers. Plus, warranty durability and construction of the RFID reader.

Factors Deciding the Best Animal Tag Reader

Here are the factors that will help you decide which animal tag reader is the best.

Read Range

The foremost factor is important in deciding the best animal reader. Read range helps decide how close the reader must be to catching the RFID signals. Finding the right read range based on your application is also important. For example, if you have a large farm covering a wide area, you need a longer range. Further, opt for passive RFID readers if you are operating from a short range. Otherwise, active RFID readers are a good choice for long-range signals.


Another factor you should consider before buying an animal tag reader is durability. Choose tags that promise durability even in harsh weather. Usually, when animals carry these RFID tags, they become vulnerable to dust, dirt, and water. You should always choose tags from reliable brands that can withstand rough weather. Opt for waterproof and rust-proof material.

Battery Life

Check the battery life if you are investing in active RFID animal reader tags with built-in batteries. It is crucial to invest in readers that offer long-lasting battery life. So they can withstand extended uses without the demand for frequent charging.

Data Storage

Before buying an animal tag reader, consider the RFID reader’s data storage capacity. Some readers can store data internally, while others support various data transfer modes, such as USB and Bluetooth. Thus, choose the data storage systems that seamlessly integrate with your systems.


Different RFID systems are available on the market. Each operates at different frequency ranges. You can choose from low-frequency (LF), high-frequency (HF), and ultra-high frequency (UHF). But, each frequency range has its advantages and limitations. Let us understand that:

  • Low-Frequency Range

The low-frequency range is 125-134 kHz. It offers short read ranges of up to 10 cm. Further, RFID readers in this range are less sensitive to signal interference. They are primarily used for livestock tracking.

  • High-Frequency Range

The high-frequency range varies up to 13.56 MHz. Such readers work effectively for moderate read ranges (up to 1 meter). They are preferred if you are looking for proximity scanning.

  • Ultra High-Frequency Range

As the name suggests, the ultra-high-frequency range is between 300 MHz and 3 GHz. These animal tag readers are perfect for longer read ranges, up to 12 meters. A plus point is that they support faster data transfer rates. Thus, they are perfect for large farms that demand large-scale animal tracking operations.


Lastly, ensure the compatibility of your RFID reader with the type of RFID tags you are using. Imagine investing in a reader only to discover that it doesn’t follow your tags. Isn’t that terrible? It can affect your management. Remember, even a simple compatibility issue can lead to ineffective data collection. It might also increase your operational costs.

A Way Forward

In conclusion, choosing the best RFID animal tag requires proper consideration. Understand factors such as versatility and durability. Remember to invest in a reputed RFID reader manufacturer that meets your needs and consider the benefits of streamlined operations.
