Abstract: A method for controlling display of a graphical representation of a physical user token in a digital wallet application of an electronic device, where the graphical representation is specified by a token server of a token-issuing entity is described.

Abstract: A method for providing improved feedback to a user during an electronic contactless interaction between a first contactless device and a second contactless device, where at least one of the first contactless device and the second contactless device is associated with a specific user, is described. The method comprises: receiving interaction data relating to the electronic contactless interaction, the data including at least an outcome of the contactless interaction and information identifying the user; determining, using the received interaction data, user preference data associated with the user; generating a control signal based at least on the outcome of the electronic contactless interaction and on the user preference data, the control signal configured to cause at least the first contactless device to generate feedback in dependence on the outcome and the user preference data; and outputting the control signal to at least the first contactless device.

Abstract: A computer-implemented method for identifying a user in each of two separate domains using a single user identifier via a single identification system so as to permit authorisation of at least one action, the method comprising: receiving a request to identify the user and authorise an action in the first domain; performing a first identification process to identify the user in the first domain, the first identification process comprising: receiving input data relating to a user at an identification system; obtaining a first user identification key from the input data for identifying the user in a first domain and for authorising an action based upon the identification in the first domain; identifying the user in a first domain by using the first identification key; authorising an action based at least in part on the identifying step: and terminating the first identification process; and performing a second identification process to identify the user in the second domain after the first user identification key

Abstract: A method of selecting a component of optimal design comprising automated steps of a) measuring the periphery of at least part of said component; b) producing a 2D co-ordinate dataset (20) from said measurements; c) processing the 2D co-ordinate dataset (20) so as to produce a representation of characteristics of the periphery of the component; d) assigning a value to the difference between the characteristics of the periphery of the component and characteristics of a component of optimal design; and e) conducting a parametric analysis of the differences between the characteristics of the periphery of the component and the characteristics of a component of optimal design. The method further comprises the step of using the results of the parametric analysis to determine whether the component meets a predetermined criteria for acceptability.
