Keeping track of livestock can be a daunting task. Especially if you have a big farm with lots of animals. Luckily there are technology which is great to use just for this purpose. Radio-frequency identification or RFID is a small tracking unit that is implanted in each animal. With a RFID reader and RFID inventory system you can then keep track of your livestock.
Unlike a barcode, the RFID device does not need to be in sight of the reader for it to pick it up. The two main type of power sources for a RFID device is the passive tag which collects energy from the nearby RFID reader’s reading radio waves. There is also a local device where the battery is close to the RFID devices, from which they draw their power. These type of power sources operate miles away from the actual reader.
RFID devices are used in various industries with great success.
