Blockchain Registered Reusable Bag Payment System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The adoption of reusable shopping bags in retail environments is slow due to lack of incentive, leading to environmental harm from disposable plastic bags, and existing payment systems do not effectively facilitate the use of reusable bags as a payment method.
Innovation Solution
A blockchain-based system where reusable shopping bags are registered as payment instruments, allowing customers to use them for transactions without cash or cards, accumulating credit for discounts or payments, and providing retailers with transparent data to incentivize their use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If reusable shopping bags are introduced to reduce plastic waste, then environmental harm is reduced, but customer adoption is slow due to lack of incentive
Solution Approach 1:
The system implements a feedback mechanism where reusable bags are equipped with tracking technology (RFID, NFC, or QR codes) that automatically records usage. This usage data is fed back to customers through mobile apps or web portals, showing them their contribution to reducing plastic waste. The feedback loop creates intrinsic motivation by making customers aware of their environmental impact, thereby increasing adoption rates without requiring external incentives.
Solution Approach 2:
A blockchain-based intermediary system is introduced to mediate between retailers, customers, and environmental impact tracking. The blockchain network verifies and records bag usage transactions transparently, creating a trusted platform that enables incentive programs. This intermediary layer facilitates credit accumulation and redemption systems, allowing customers to earn rewards for reusable bag usage, thus bridging the gap between environmental goals and customer motivation.
2Reliability
If traditional electronic payment systems are used with trusted third parties, then transaction security is maintained, but payment processing complexity and time are increased
Solution Approach 1:
The patent extracts the trusted third party (bank or payment processor) from the payment transaction flow by implementing direct peer-to-peer payments through blockchain technology. Cryptographic key pairs replace traditional authentication mechanisms, allowing customers to make payments directly from their digital wallets without intermediary involvement. This extraction simplifies the payment system architecture while maintaining security through cryptographic verification, reducing both processing time and system complexity.
Solution Approach 2:
The system creates digital copies of physical reusable bags on the blockchain as non-fungible tokens (NFTs) or digital assets. Each physical bag has a corresponding digital twin that stores its identity, ownership, and usage history. This digital copy enables automated recognition and verification at point-of-sale terminals, eliminating the need for complex manual verification processes while maintaining transaction security through blockchain's inherent cryptographic protocols.
3Loss of information
If blockchain technology is implemented for bag registration and payment, then transparency and incentive mechanisms are improved, but system complexity and implementation cost are increased
Solution Approach 1:
The blockchain system is segmented into modular components: a registration module for bag identification, a tracking module for usage monitoring, and a payment module for transaction processing. Each module operates independently but communicates through standardized blockchain interfaces. This segmentation allows retailers to implement only the necessary functions for their specific needs, reducing overall system complexity while maintaining transparency benefits. The modular architecture also enables phased implementation, starting with basic tracking and gradually adding payment and incentive features.

AI summary
Systems and methods of conducting a payment transaction via a blockchain registered container at a point of sale are presented. In one exemplary embodiment, a method is performed by a POS system having a sensing device operable to sense an identifier specific to a container configured to transport items after checkout. The POS system is communicatively coupled to a blockchain network that includes network nodes that are collectively configured to operate a blockchain. The container identifier is specific to a cryptographic digital asset stored on the blockchain as a container identifier code. Further, the cryptographic digital asset includes a code that represents an electronic payment instrument identifier configured to enable an electronic payment transaction based on the container identifier sensed from the container. The method includes sending, to the blockchain, a request for block data associated with the cryptographic digital asset based on the container identifier.
