This module gives you global information regarding the Point of Sales application. You will better understand its way of working and why it can sometimes lead to limitations. Indeed, the POS app has a technical component which needs to be understood before starting a project implementation.
We will start with an introduction to the POS app, followed by technical specificities and finally tackle some more functional aspects that are important to understand in order to realize a successful app implementation. 

This module targets users who already have basic knowledge. Therefore, you need to work on the following prerequisites : 

What are the different levels of access rights in the POS ? 
Giving the right access rights to the different users that are going to be using the database is a crucial step during the implementation process. The different levels of access will define what information the user can read, write, create or delete.
We have 3 levels of access in the POS app:
1.	POS Administrator : he has access to all configurations, features and reports. Some POS settings are referring to the “POS manager”: it is actually the “POS Administrator”. 
2.	POS User : He has no access to reports and configurations.
3.	Authorized Employee : if the “Authorized Employees” feature is activated, only POS Users that have their Employee name in the list will be able to log in the Point of Sale.
Further, the cash in/out feature won't be available for POS Users. For POS Administrators this feature will never be blocking (cash in/out).
