Abstract
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 display, a touch panel, first electronics in a physically secure area and second electronics in a non-secure area. The first electronics are configured to display a series of screens to guide a consumer through the POS transaction. The second electronics comprises a microcontroller and a secure processor. Upon receiving a request for secure data from the non-secure processor, the secure processor sends a notification to the non-secure processor to exit pass-through mode and enter a secure touch mode. Upon completion of PIN entry, the secure processor instructs non-secure processor to exit secure touch mode and return to pass-through mode.
