Disclosed herein are systems, methods, and non-transitory computer-readable storage media for sending transfer requests, receiving approvals, and carrying out transfers in a digital wallet application. A mobile payment engine receives a request from a client application associated with a first digital card to apply assets from at least one additional digital card to the first digital card, receives receiving approval to transfer assets from the at least one additional digital card to the first digital card, and transfers the assets to the first digital card. Transfers can be made between digital cards in the same client's digital wallet application and transfers can be made between multiple client device accounts.
