1. A method of payment terminal operation, the method comprising:
- receiving a payment collection request from an application at a main processor connected to a secure display corresponding to a secure input device;
generating a payment initiation request in response to receipt of the payment collection request by the main processor;
sending the payment initiation request from the main processor to a secure processor separate and distinct from the main processor, wherein the payment terminal comprises the main processor, the secure processor, and a housing retaining the main processor and the secure processor;
switching the secure processor from operation in an unsecured mode to operation in a secured mode in response to receipt of the payment initiation request, wherein the secure processor forwards input coordinates received from a secure input processor to the main processor in the unsecured mode and ceases input coordinate forwarding in the secured mode;
receiving payment instrument data by the secure processor from payment hardware;
selecting a display element from a fixed set of predetermined display elements based on the payment instrument data by the secure processor;
sending a request to display the selected display element on the secure display from the secure processor to the main processor;
receiving, at the secure processor, input coordinates generated by the secure input processor based on input signals from the secure input device within a predetermined time duration after sending the request; and
interpreting the input coordinates based on a coordinate map associated with the display element by the secure processor, independent of display elements concurrently displayed on the secure display during receipt of the input signals.
