A system for managing data, the system comprising: a memory operable to store one or more existing sets of data, each existing set of data being associated with one or more existing data attributes and a corresponding data set identifier, an interface for communicating with one or more service provider systems (110-1, 110-2,..., 110-n, 210, 310, 410, 510, 610), and a processor communicatively coupled to the memory and the interface, the processor being operable to: receive, from the one or more service provider systems (110-1, 110-2,..., 110-n, 210, 310, 410, 510, 610) via the interface, a change request including at least a data set ID and instructions to delete one of the one or more existing sets of data stored in the memory; query the memory for a set of data among the one or more existing sets of data having a data set ID matching the data set ID included in the change request; and process the change request in accordance with the instructions wherein the processor is operable to process the change request by: identifying, based on the data set ID, one or more mobile devices (130-1, 130-2,..., 130-n, 230, 330, 430, 530, 630) on which the set of data among the one or more existing sets of data having a data set ID matching the data set ID included in the change request is stored in a mobile wallet application (131-1, 131-2,..., 131-n); and transmitting a request to delete the set of data among the one or more existing sets of data having a data set ID matching the data set ID included in the change request from the mobile wallet application (131-1, 131-2,..., 131-n) stored on the one or more mobile devices (130-1, 130-2,..., 130-n, 230, 330, 430, 530, 630). a memory operable to store one or more existing sets of data, each existing set of data being associated with one or more existing data attributes and a corresponding data set identifier, an interface for communicating with one or more service provider systems (110-1, 110-2,..., 110-n, 210, 310, 410, 510, 610), and a processor communicatively coupled to the memory and the interface, the processor being operable to: receive, from the one or more service provider systems (110-1, 110-2,..., 110-n, 210, 310, 410, 510, 610) via the interface, a change request including at least a data set ID and instructions to delete one of the one or more existing sets of data stored in the memory; query the memory for a set of data among the one or more existing sets of data having a data set ID matching the data set ID included in the change request; and process the change request in accordance with the instructions wherein the processor is operable to process the change request by: identifying, based on the data set ID, one or more mobile devices (130-1, 130-2,..., 130-n, 230, 330, 430, 530, 630) on which the set of data among the one or more existing sets of data having a data set ID matching the data set ID included in the change request is stored in a mobile wallet application (131-1, 131-2,..., 131-n); and transmitting a request to delete the set of data among the one or more existing sets of data having a data set ID matching the data set ID included in the change request from the mobile wallet application (131-1, 131-2,..., 131-n) stored on the one or more mobile devices (130-1, 130-2,..., 130-n, 230, 330, 430, 530, 630). receive, from the one or more service provider systems (110-1, 110-2,..., 110-n, 210, 310, 410, 510, 610) via the interface, a change request including at least a data set ID and instructions to delete one of the one or more existing sets of data stored in the memory; query the memory for a set of data among the one or more existing sets of data having a data set ID matching the data set ID included in the change request; and process the change request in accordance with the instructions wherein the processor is operable to process the change request by: identifying, based on the data set ID, one or more mobile devices (130-1, 130-2,..., 130-n, 230, 330, 430, 530, 630) on which the set of data among the one or more existing sets of data having a data set ID matching the data set ID included in the change request is stored in a mobile wallet application (131-1, 131-2,..., 131-n); and transmitting a request to delete the set of data among the one or more existing sets of data having a data set ID matching the data set ID included in the change request from the mobile wallet application (131-1, 131-2,..., 131-n) stored on the one or more mobile devices (130-1, 130-2,..., 130-n, 230, 330, 430, 530, 630). identifying, based on the data set ID, one or more mobile devices (130-1, 130-2,..., 130-n, 230, 330, 430, 530, 630) on which the set of data among the one or more existing sets of data having a data set ID matching the data set ID included in the change request is stored in a mobile wallet application (131-1, 131-2,..., 131-n); and transmitting a request to delete the set of data among the one or more existing sets of data having a data set ID matching the data set ID included in the change request from the mobile wallet application (131-1, 131-2,..., 131-n) stored on the one or more mobile devices (130-1, 130-2,..., 130-n, 230, 330, 430, 530, 630).
