Abstract

A point-of-sale (POS) system used in performing a POS transaction between a merchant and a consumer. The POS system includes a display having a touch panel, a main processor and a memory device. The POS system also includes a secure enclave with a secure processor and a microcontroller. The main processor is configured to display a series of screens to guide a consumer through the POS transaction. The microcontroller provides the inputs from the touch panel to the main processor when the POS system is operated in a pass-through mode and provides the inputs from the touch panel to the secure processor when the POS system is operated in a secure touch mode.
