LoyaltyCard

A Solidity contract that implements a loyalty card system.

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.
