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

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.
