In Cashy-POS you can define up to 8 users or sellers in the user-settings.

The name given in the settings are shown on these buttons. Tapping one of the user-buttons immediately changes the user (shown on top of the transaction-screen) and all transactions are associated to this user until a new user has been chosen.

No password is needed to toggle between users.

A long tap onto one of the users buttons will print a short report containing the amounts of the different  payment methods cashed from this seller/user since last close-day in ‹Z›-mode
