Abstract: The retailers of supermarkets today quite often use the transactional marketing strategy to entice their customers by issuing discount coupons. The proposed system aims at enhancing this reward-based system and automating customer shopping experience by building a 'pay as you choose the item' technology. Employing such a system would help in providing a faster, safer and more convenient means of transaction alongside improving the overall efficiency of the supermarkets achieving higher revenue with lesser manpower. The authors utilise the concept of blockchain to perform transactions using a cryptocurrency called value-coins. Such a digital system would be commonly available to all the outlets of the retailer.
Keywords: value-coins; proof of authority; PoA; digital signature; blockchain; consensus algorithms; layer pattern architecture.
