With public ledger digital cash payments comes a new type of point of sale (POS) system which has been implemented by several devices and apps. The "payment verification model" for POS minimizes security risk and associated fees while enabling merchants to adopt their point of sale system to different numéraires and different payment currencies. In this paper we outline this system and its advantages and operation. We provide the first systematic security taxonomy, privacy mitigation strategies, and accounting integration guidance specifically for payment verification POS systems.
