摘要 |
A method and apparatus are disclosed for identifying a characteristic of a bulk flowable material. An identification marker is inserted into a bulk flowable material. The identification marker carries information identifying a specified property or properties of the material. A marker dispenser can be located at one or more handling sites of the bulk flowable material. The identification markers can be pre-prepared or property-related information can be added to the marker prior to or subsequent to dispensing. The identification markers can be paper-like labels, for example, or more complex devices. The system can be used to track the lifespan of a material or to indicate a property of the material to others, such as whether the material is a genetically modified organism (GMO). A pre-printed marker source containing a single continuous bar code is also disclosed.
