Abstract: A method of measuring parameters associated with a website comprising a complex hierarchy of web pages is described. The method is used for a website adapted to support a user journey through multiple web pages to a user destination. The user journey is defined as a sequence of functional steps. A machine learning system is provided which is trained to provide a website navigation system adapted to navigate from a landing screen to a destination screen by performing each functional step in the sequence. The website is then navigated from the landing screen to the destination screen for that website using the website navigation system. One or more parameters resulting from, or associated with, one or more steps of the journey from the landing screen to the destination screen for the website are measured. A computing system suitable for performing the method, and a method of building a suitable website navigation system are also described.

Abstract: A digitized card data structure is stored in association with a digital card environment. The digitized card data structure corresponds to a card issued to a card holder. The digitized card data structure has a component for providing output to the card holder. Under a first condition the component provides a first output and under a second condition, the component provides a second output different from the first output.
