Abstract: Systems and methods for secure transaction interfaces. In one implementation, a processing device receives, within a user input interface and while a user communication agent is presented at a display interface of a device, a selection of a transaction initiation control, presents, in response to the selection of the transaction initiation control and via the user input interface, a transaction execution control, presents, in response to a selection of the transaction execution control, identifier(s) via an identifier selection control, receives a selection of the identifier(s), transitions, in response to the selection of the identifier(s), the user input interface into a numeric input interface, receives a numeric input via the numeric input interface, activates a transaction confirmation control within the user input interface, and executes, in response to a selection of the transaction confirmation control, a secure transaction with respect to the selected identifier(s) and the numeric input.
