Abstract: Methods and systems for generating and validating electronic tickets are disclosed. The systems include a server that is configured to host a centralized website through which a computer application may be downloaded into a plurality of user devices. The server is further configured to issue electronic tickets to the user devices that have downloaded the computer application; embed an encrypted visual identifier that is unique to an event in each electronic ticket; generate instructions to be issued to an event administrator that identifies a decrypted form of the visual identifier for each event; and include instructions within each electronic ticket that may be executed by an event administrator to convert the encrypted visual identifier that is shown in the electronic ticket of each user device into the decrypted form of the visual identifier.

Abstract: A method for detecting a two-dimensional bar code pattern using a bar 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 sym
