Background and Purpose of the Project

In the context of the current service industry, the payment and receipt of tips is often a complex and opaque process. This state of affairs affects the quality of service and may lead to lower consumer satisfaction. Traditional tip payment methods, such as cash transactions or credit card payments, often involve longer processing time and privacy security. Trust between service providers and consumers is also affected by the lack of standardization and transparency.

To address these challenges, we propose the “Tips Payment and Receive System”. The core objective of this project is to revolutionize the tipping transaction process through digital means, thereby improving the efficiency and transparency of the entire service industry.

• NFC Payment Technology: Utilizing Near Field Communication (NFC) technology, consumers can complete payments through simple proximity contact with their cell phones, greatly enhancing the convenience and speed of payments.
• QR-Code payment method: Payment can be completed quickly by scanning a QR code, which is suitable for young users who are technically proficient, and at the same time convenient for those who prefer traditional payment methods.
• Face Recognition Payment System: Introducing advanced face recognition payment technology. This will enhance the security of the payment process and provide a contactless and efficient payment experience.
• Sensorless Payment Integrated with Mainstream Cashiering Systems: The system will be seamlessly integrated with existing mainstream cashiering systems, allowing consumers to pay automatically based on the total amount of their bill without any additional operations.

1.2 Main Functions and Innovations

A) Smart Contract Application

• Core technology: Adoption of smart contracts in blockchain technology to ensure the transparency and non-tampering of all transactions.
• Practical Application: Smart Contracts will automatically execute pre-set payment conditions and protocols, ensuring automation and standardization of transactions and reducing manual intervention and errors.
• Enhanced Trust: Through blockchain technology, trust between service providers and consumers is enhanced as all transaction records are transparent and unalterable.

B) Automated Billing

• Seamless Integration: The system seamlessly integrates with existing mainstream cashiering systems, automatically calculating tips and making reasonable payment suggestions.
• Enhanced Efficiency: Automated bill processing greatly reduces labor costs and improves the speed and accuracy of billing.
• User-friendly: Simplifies the payment process and provides users with a smoother and more convenient payment experience.

C) Rating and Feedback Mechanisms

• Interactive experience: Allows for mutual ratings between payers and receivers, which in turn motivates the provision of better quality services.
• Quality Assurance: The rating system helps to maintain the quality of service as it provides direct customer feedback to the service provider.

D) Highly anonymous encryption algorithms

• User privacy protection: Through encryption algorithms, the user’s transaction data is strongly protected, effectively preventing the leakage of personal information.
• Defense against attacks: The Cryptonight algorithm improves the system’s ability to defend against network attacks (such as double-flower attacks) and protects the stability and reliability of the entire payment system.

E) Renting Arithmetic Power to Earn Extra Revenue

• Innovative use: Users can use the tips they receive to rent arithmetic power and generate cryptocurrency revenue.
• Diversification of income: Provide a new source of income for workers in the service industry and increase the diversity of personal income-generating channels.
• Financial Inclusion: Lowering the barrier to entry into the cryptocurrency market and providing opportunities for ordinary users to participate in digital currency mining.
