Abstract: Techniques described herein are directed to integration of multi-user interactions using data linkage. The techniques include receiving a request to initiate a transaction associated with a condition for purchase of an item and causing indicators of user profiles to be presented via a user interface. Input data indicating a selection of a user profile is received and an interactive element can be generated and embedded with data that allows for the user profile to participate in the transaction. Based on sending the interactive element to a user device, an indication that the user has requested to participate in the transaction can be received and payment of the transaction can be facilitated using an account associated with the first user profile, an account associated with the second user profile, and/or an account associated with a service provider.

Abstract: A computer-implemented method for facilitating payment of a total amount comprising multiple future instalments by a customer (3), the method comprising: receiving, at an instalment payment server (5), an indication from a mobile device (7) associated with the customer (3) to set up the payment by the multiple future instalments; generating first authorisation data indicative of an authorisation of the multiple future instalments; sending the first authorisation data to a mobile device (7). The method may include displaying on the mobile device (7) an optical machine readable representation of the first authorisation data; and scanning, by a merchant POS system (13) associated with a merchant (11), the optical machine readable representation of the first authorisation data from the mobile device (7).
