A specific profile is created, with multiple employees associated with it (in this example, the yellow profile).
This profile is specifically checked as the only one that can access the given point of sale.
Only the employees of the profile can be considered as salespeople.
It is possible to log in to PrestaShop with any employee account and then access the cash register.
If the option "Ask for salesperson identification at each sale?" is NOT enabled, the salesperson must identify themselves when accessing the cash register interface. As long as they do not leave this interface, they do not need to identify themselves again.
If this option is enabled, identification will be required before each sale.
In all cases, it is possible to change the salesperson by clicking on the salesperson icon in the upper right corner of the cash register interface.
