A Systematic Review of IoT Applications: Security & Privacy Issues

Abstract

Customers around the world are increasingly utilizing supermarkets to purchase goods. Supermarkets offer a large variety of products at competitive prices, making them a popular choice for shoppers. Supermarkets often have a wide variety of fresh produce, packaged groceries, bulk items, prepared foods, and sometimes a pharmacy and other services. Customers can conveniently purchase their desired products in one place and often find discounted prices, making the supermarket a cost-efficient option for grocery shopping. Shopping carts or baskets are often seen in supermarkets as a way for customers to carry their purchased items throughout the store. Shopping carts enable customers to quickly purchase more items than they could carry alone and the basket is used for smaller items. Depending on the store, customers can often rent the shopping cart or they can use their own reusable basket.
