How to choose LF ear tag or UHF ear tag?

RFID animal ear tags use radio frequency identification technology and are specifically used to identify individual animals in the livestock industry. It is small and portable, can be fixed on the ears of livestock, and transmits unique electronic codes through wireless radio frequency signals to achieve precise tracking and management of each animal.

 

   When it comes to ultra-high frequency (UHF) and low-frequency (LF) RFID animal ear tags, they each have different advantages and disadvantages. Let's explore this in detail:

 

1. Low-frequency RFID animal ear tags:

 

Frequency band range: Low-frequency RFID usually operates in the 125 kHz or 134.2 kHz frequency band.

 

Application: Low-frequency RFID ear tags are often used for identification of individual animals in the livestock industry. It is widely used in large-scale cattle and sheep farms abroad. For example, when the domestic border inspection office counts imported animals for epidemic prevention, they will use low-frequency electronic ear tag readers installed at the passage doors to count each animal one by one to avoid cross-reading problems.

 

Advantage:

 

1. Stability: Low-frequency RFID ear tags show better stability in harsh environments, such as wet, dusty or places with high electromagnetic interference.

 

2. Adaptability: Suitable for most animals, including cattle, pigs, sheep, horses, etc.

 

3. Recognition distance: Although it is short, the recognition effect is good at close range.

 

4. Cost: Relatively low hardware cost, suitable for large-scale applications.

 

Low-frequency RFID animal ear tags will not cause cross-reading and are suitable for one-to-one identification.

 

Disadvantages:

 

1. Limited recognition distance: The recognition distance of low-frequency RFID ear tags is usually short and requires proximity to the card reading device.

 

2. Slow data transmission speed: Compared with high frequency, the data transmission speed is slow.

 

2. UHF RFID animal ear tags:

 

Frequency band range: UHF RFID typically operates in the 860 MHz to 960 MHz frequency band.

 

Application: my country's Animal Husbandry Bureau stipulates that ultra-high frequency ear tags can be worn in pig, cattle, and sheep breeding. When using a reader-writer to identify animals, it has the characteristics of batch reading, fast reading speed, and long reading distance.

 

Advantage:

 

1. Longer identification distance: UHF RFID ear tags have a longer identification distance and are suitable for scenarios that require long-distance reading.

 

2. Fast data transmission speed: UHF RFID ear tags can transmit data faster.

 

3. Multi-tag processing: Supports reading multiple tags at the same time.

 

4. UHF RFID readers are also more compact.

 

Disadvantages:

 

1. Higher cost: The hardware cost of UHF RFID ear tags is usually higher.

 

2. Affected by metals and liquids: Metals and liquids can interfere with UHF RFID signals.

 

3. When performing batch reading and inventory counting, cross readings and missed readings are prone to occur.

 

   In short, choosing an RFID ear tag suitable for a specific application scenario requires comprehensive consideration of its performance, cost and environmental factors. Low-frequency RFID ear tags are suitable for one-to-one identification and low-cost inventory of individual animals in the livestock industry, while ultra-high-frequency RFID ear tags are more suitable for scenarios that require batch reading, long-distance identification, and high-speed data transmission.
