A bale identification assembly has a binding material with identification tags at spaced intervals is used by a knotter system to bind a formed bale. A read module with an antenna transmits interrogator signals and also receives authentication replies from identification tags. The bale identification assembly has a bale drop sensor with a paddle. As a completed bale passes through the discharge chute, the completed bale interacts with the paddle causing the bale drop sensor to activate. Activation of the bale drop sensor activates the antenna for a specified active cycle, and during its active cycle, the read module assigns any identification tag that is sensed to the completed bale that is leaving the discharge chute. A controller receives information from at least one crop sensor and/or bale sensor and associates the information about the completed bale with the identification tag on the completed bale.
