MASSPAY is a mobile payment system that allows any phone to make contactless payments without modifications or extra hardware. It addresses the problems of cash dominance and the complexity of existing mobile payment solutions. The system works by scanning a merchant's sticker or dialing their number, confirming payment details, and receiving an SMS confirmation. MASSPAY turns any phone into a payment instrument and aims to be simpler than alternatives while avoiding niche approaches. It is developed by an experienced team and aims to benefit both merchants and consumers by increasing sales and convenience without heavy investments.
