Using ZDCARD RFID ear tags has many advantages:

1. It offers another form of identification for each animal. Sometimes visual tags get lost, become snagged on a fence, etc, whereas ear tags are small and are designed for high retention rates.
2. An animal can more quickly be identified in the chute (by scanning the tag with a reader) rather than needing to have the animal be completely still to read a visual tag or tattoo number.
3. Scanning RFID ear tags, instead of manually writing down an ear tag number, offers tremendous time-saving benefits while minimizing errors. As cattle are being worked or loaded into a trailer, their RFID ear tag can be scanned while they are on the move.
