What is the most effective RFID tag to track livestock?

2 Passive RFID tags

Passive RFID tags are the simplest and cheapest type of RFID tags. They have no battery and rely on the reader's signal to activate and transmit their information. They have a short range, usually less than 10 meters, and a low memory capacity, usually less than 2 kilobytes. They are ideal for applications that require low-cost, high-volume, and short-distance identification, such as animal identification in slaughterhouses, markets, or feedlots. However, they have some drawbacks, such as being susceptible to interference from metal or liquids, having a low data transfer rate, and being difficult to read in crowded or noisy environments.

3 Active RFID tags

Active RFID tags are more complex and expensive than passive RFID tags. They have a battery that powers the microchip and the antenna, and can initiate communication with the reader. They have a long range, up to 100 meters, and a high memory capacity, up to 128 kilobytes. They are ideal for applications that require high-performance, long-distance, and real-time identification, such as animal tracking in large farms, ranches, or wildlife reserves. However, they have some drawbacks, such as being bulky, heavy, and costly, having a limited battery life, and being vulnerable to hacking or tampering.

4 Semi-active RFID tags

Semi-active RFID tags are a hybrid between passive and active RFID tags. They have a battery that powers the microchip, but not the antenna, and can respond to the reader's signal. They have a medium range, up to 30 meters, and a medium memory capacity, up to 64 kilobytes. They are ideal for applications that require moderate-performance, medium-distance, and intermittent identification, such as animal monitoring in dairy farms, breeding facilities, or quarantine zones. However, they have some drawbacks, such as being more expensive than passive RFID tags, having a shorter battery life than active RFID tags, and being affected by interference from metal or liquids.

5 How to choose the most effective RFID tag for your livestock?

When it comes to choosing the right RFID tag for your specific needs and goals, there is no one-size-fits-all answer. You need to take into account factors such as the size, shape, and weight of the tag, its durability and reliability, its cost and availability, and its performance, functionality, and scalability. As a rule of thumb, pick the type of RFID tag that offers the best balance between these factors and that delivers the most value for your money. Additionally, it’s wise to consult with experts, suppliers, and peers who have experience with RFID tags for livestock management.
