<p>A method and system for verifying the presence of an individualised object in an object conveying system is provided, where the object is one of a plurality of similar but otherwise distinctly individualised objects. The method includes the steps of: sequentially conveying a group of said objects past a first and optionally past a second identification station arranged to read an indicia representative of the individualisation of each object; reading of the indicia of a first such object when present at the first identification station; reading of the indicia of a second such object when present at the first or the second identification station; comparing the first and second indicia against a set of criteria and providing a positive or negative result of said comparison; and allowing said first object to be conveyed to a first location upon said comparison result being positive and otherwise conveying said first and second objects to a second location upon comparison result being negative.</p> |
