An apparatus for conducting an interaction through established connections using ultra-wideband comprises a processor associated with a server. The processor is configured to receive a request to initiate an interaction between a grouping and an entity device associated with an entity. The processor is further configured to receive user device information for each user device in the grouping based on universal device identifiers. The processor is further configured to determine an account associated with a user based on comparing the received user device information to the stored user device information. The processor is further configured to transmit the interaction to each user device within the grouping. In response to receiving a request from one of the user devices in the grouping to split the interaction, the processor is further configured to conduct at least a first part of a split interaction with the determined account associated with the user.
