The creation of POS systems is frequently contracted out by retailers to outside developers.
POS systems are a vital part of modern retail environments. They help merchants manage their sales records, track inventory, and process payments. As technology continues to advance, so too does the functionality of POS systems. Today, they are capable of performing a wide variety of tasks, including processing payments and tracking inventory.

As technology continues to evolve, POS systems will continue to play an important role in the management of retail operations.
What is Use Case Diagram?
A use case diagram is a visual representation of the different ways a user can interact with a system. It is a useful tool for software developers as it can help them to map out the functionality of a system and understand how different users will interact with it.
A use case diagram typically contains three types of elements:
Actors: These are the people or systems who will be performing the desired functionality.
Activities: These are the specific tasks that the actors will carry out.
Connections: These show how the activities and objects in one use case relate to those in other use cases
