    Customers visit a retail store and use their mobile phone camera to scan barcodes to add items to their shopping cart. The shopping cart is held in a cookie. They can remove an item from their cart, they can add more quantity of an item. Once they pay, the shopping cart is transferred to their invoice bill, and a corresponding reduction of the store inventory takes place. The project is completed in about 9/10 steps. Source code is given/included.

    This ASP.NET Core Project is a proof of concept that allows a user to keep a record of the locations that an android phone travels. The user has to first pair his device to this portal. For this the user has to install the android app [source code of the C# .NET MAUI project is attached]. When this app is opened the first time, it shows a pairing code. The user has to enter that pairing code in the ASP.NET Core Portal (see intro video). Custom middleware has been used to store location data of each user (tenant) in a separate database. Source code is given/included.
