LoyaltyCard Contract
This contract allows businesses to create and manage loyalty cards for their customers. Customers can earn points for purchases and redeem them for rewards.
Features
- Create and manage loyalty cards
- Track customer points
- Redeem points for rewards
- View customer loyalty card details
Usage
To use the LoyaltyCard contract, a business owner first deploys the contract. They can then create new loyalty cards for their customers. When a customer makes a purchase, the business owner can call the `addPoints` function to award points to the customer. Customers can then redeem their points for rewards by calling the `redeemPoints` function.
Implementation Details
The contract uses a mapping to store the loyalty card details for each customer. The `addPoints` and `redeemPoints` functions update the customer's points balance accordingly.
Best Practices
- Use a secure random number generator to generate unique loyalty card IDs.
- Implement access control to prevent unauthorized access to customer data.
- Consider using a decentralized storage solution to store loyalty card data.
