Abstract

A payment terminal includes multiple chips that perform different processing functions within the payment terminal. A terminal chip performs general functionality of the payment terminal while a transaction chip communicates with payment devices such as chip cards and NFC payment devices and processes payment information. The transaction chip may operate in a low power during which communications and processing are limited, and a transaction processing mode in which transactions may be processed. The transaction chip may transfer between these modes based on wake-up messages provided by other devices or circuitry of the payment terminal.
