Solution

🔑 The solution around which we will create the system design today:

Payment:

1.. A basic food delivery system design

• Swiggy can explore offering additional payment options to users, such as support for new payment methods or partnerships with other payment providers.
• This can help users who may not have access to traditional payment methods like credit cards, or who may prefer to use a specific payment method for security or convenience reasons.

2.. Address technical glitches

• Swiggy can work to address any technical glitches or security concerns related to online payments, such as issues with payment gateways or delays in processing payments.
• Swiggy can also implement additional security measures to protect users’ payment information and prevent fraud.

3.. Simplify the payment process

• Swiggy can simplify the payment process by reducing the number of steps required to complete a transaction, and by making the payment process more intuitive and user-friendly.
• This can help users complete their orders more quickly and easily, which can improve the overall user experience.

4.. Provide clear and transparent pricing information

• Swiggy can provide clear and transparent pricing information to users, including any fees or charges that may apply to their order.
• This can help users make informed decisions about their purchases and avoid any surprises when it comes time to pay.

By implementing these solutions, Swiggy can improve the overall user experience, build trust with customers, and differentiate themselves from their competitors in the highly competitive food delivery market.

High Level System — Design

A basic food delivery system design

Based on the proposed solutions for Swiggy’s payment feature, the high-level system design could include the following components and their functionalities:

1. Payment Gateway: The payment gateway component is responsible for securely processing and authorizing transactions between Swiggy, the user, and the user’s financial institution. It will also ensure that the transaction details are properly recorded and stored.
2. Payment Options: This component would offer multiple payment options to users, such as credit cards, debit cards, net banking, mobile wallets, and UPI. It would also partner with other payment providers to support new payment methods and expand the reach of the platform.
3. Security and Compliance: This component would ensure the security and compliance of the payment process, including data encryption and two-factor authentication. It would also monitor and prevent fraudulent activities and unauthorized access to users’ payment information.
4. User Interface: This component would provide a simple and intuitive interface for users to select and complete their preferred payment method. It would also display clear and transparent pricing information, including any fees or charges that may apply to their order.

Interactions & Dependencies

The interactions and dependencies between these components can be visualized as follows:

• The User Interface component would interact with the Payment Options component to display the available payment methods to users and enable them to select their preferred option.
• The Payment Options component would interact with the Payment Gateway component to initiate and process the payment transaction based on the user’s selected method.
• The Security and Compliance component would interact with all other components to ensure the security and compliance of the payment process, including user authentication, data encryption, and fraud prevention.

Data Flow

The data flow within the system would include the following:

Explanation:

• User selects the preferred payment option from the User Interface component.
• The User Interface component sends the user’s payment request to the Payment Options component.
• The Payment Options component selects the appropriate payment gateway and sends the payment request to the Payment Gateway component.
• The Payment Gateway component interacts with external payment providers and financial institutions to authorize and settle the transaction.
• The Payment Gateway component sends the payment confirmation to the Payment Options component.
• The Payment Options component sends the payment confirmation to the User Interface component.
• The User Interface component displays the payment confirmation to the user.

Assumptions

🚧 Assumptions made during the design process include:

• Assumption 1: The payment gateway component will be provided by a third-party payment processor, and will be integrated into the Swiggy platform.
• Assumption 2: The payment options module will provide users with a range of payment options, including support for new payment methods or partnerships with other payment providers.
• Assumption 3: The security module will include features such as two-factor authentication and fraud prevention measures to ensure that all payment information is securely stored and processed.
