In the dairy gate example, which component is used to identify the cow via ID?

Reading the cow’s ID at the gate is done with an RF antenna as part of an RFID system. The cow wears a tag that contains a unique ID, and when the cow approaches the gate, the antenna/reader picks up that tag’s ID and sends it to the system to identify which cow is present and decide what action to take. Light sensors might detect that a cow is at the gate, but they don’t provide any identity. Pneumatic arms are the mechanism that physically move the gate, not for identifying the animal. A movement sensor in the cow’s pendant can track activity, but it doesn’t give a unique ID for identification.
