EID Cattle Tags

Easier management for your dairy operation with DHI-Plus.

What is an RFID or an EID tag for cattle?

EID button and an ear tagRadio Frequency Identification (RFID) or Electronic Identification (EID) tags are a simple solution for dairy operations that need to identify a lot of cows in a short amount of time.

An EID tag is a small button that contains an embedded microchip that attaches to a regular cattle tag. Each tag and chip have the same unique 15-digit number—one for visual identification and one to use with an electronic reader.

Dairy workers scan the ear tag with a handheld RFID reader that energizes the device and reads the number coded in the microchip. That information is then sent from the reader to a handheld device that holds all the data on each individual cow. The tags are durable, and with proper placement should last the life of the animal.

How durable are EID cattle tags?

The EID tag only draws power from the electronic reader in order to transmit the ID number to the reader—this means that you never have to worry about a battery going dead. If applied properly, EID tags have a high retention rate and the need to replace the tags is generally low.
