Described herein are frameworks and methodologies configured to enable integration of booking and access control for service providers. Embodiments of the invention have been particularly developed for allowing a user to gain access to an access controlled resource (for example a hotel room or the like) via a mobile device. This preferably occurs in the context of an arrangement where access rights are provided in real time upon completion of a booking. For example, some embodiments operate in the context of a mobile app and associated supporting infrastructure thereby to provide functionality to (i) find an available suitable resource; (ii) book that resource; (iii) provide payment; and (iv) gain access via the same mobile device. In some embodiments the technology leverages third party platforms for (i) to (iii), and provides (iv) based on output from processes at the third party platform(s). While some embodiments will be described herein with particular reference to that application, it will be appreciated that the invention is not limited to such a field of use, and is applicable in broader contexts.
