The RadMarkTM bin identification system is based upon a simple concept. If you can see it you can identify it. A uniquely identifiable, x-ray visible, tag is placed under the rim of each bin. The identification code on the radiopaque tag matches the identification label on the bin. When the scanner operator selects a bin to be checked it is visually identified on the scanner screen by the ID number. The bin can then be easily segregated for further screening through visually matching the bin label.
