    Abstract: A method for detecting a two-dimensional bar code pattern using a bai code pattern reader, the bar code pattern being in the form of a matrix of rows and columns of data cells of either a first or second colour representing encoded data bits, and containing a set of at least two predetermined locating symbols at predetermined positions within the bar code pattern, wherein the method comprises the steps of: receiving a two-dimensional image containing the pattern, analysing the image to identify potential occurrences of the locating symbols within the image, validating the potential occurrences of locating symbols by analysing the potential occurrences to identify any set of occurrences whose size and relative positions within the image are consistent with the predetermined positions of the locating symbols within the bar code pattern, thereby identifying a set of locating symbols, and identifying the location of the bar code pattern within the image on the basis of the positions of the identified locating symbols. An apparatus for carrying out the method, and systems which utilise the bar code pattern, are also disclosed.
