A consumer terminal for a point-of-sale (POS) system used in performing a POS transaction between a merchant and a consumer. The consumer terminal includes a touch screen display having a touch panel, a secure processor in a physically secure area and a main processor in a non-secure area. The main processor is configured to display a series of screens to guide a consumer through the POS transaction. Upon receiving a request for secure data from the main processor, the secure processor instructs the main processor to exit pass-through mode and enter a secure touch mode. Upon a determination that the request for secure data is complete, the secure processor instructs the main processor to exit secure touch mode and return to pass-through mode.

Point-of-sale system having a secure touch mode

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.
