A content request communication, e.g., generated using a first processor of a device, can be transmitted to a web server. A response communication including content identifying a first value can be received from the web server. The first processor can facilitate presentation of the content on a first display of the device. A communication can be received at a second processor of the device from a remote server. The communication can include data representing a second value and can be generated at the remote server using information received from the web server. Further, the second processor can produce a secure verification output that can be presented on a separate, second display, representing at least the second value. The presentation on first display can at least partially overlap in time with the presentation on the second display.
