A computer-implemented method for customizing a user interface comprises receiving, from a touchpoint device, identification information entered by a user; accessing a record of the user from a database using the received identification information; determining whether the record has any application windows configured for the user interface on the touchpoint device; transmitting, by a server to the touchpoint device, at least a first financial application window and a second financial application window identified by the record of the user for display of the first financial application window and the second financial application window simultaneously on the user interface of the touchpoint device; receiving instructions from the user via the first financial application window to perform a financial transaction; and performing, by a server, the financial transaction while the touchpoint device displays at least the first financial application window and the second financial application window, wherein the first financial application window and the second financial application window are updated with real-time information.
