Terminals are where sales are processed. ie the User adds the customer and product details to the transaction and records the payment.
Cash Drawers hold the takings. Sessions are used to record the takings for a period and a Cash Drawer is removed at the end of a session. When a session is ended a new one is automatically created and the previous session becomes available to balance.
A terminal can only be assigned once - to one cash drawer. A cash drawer may have multiple terminals assigned to it.
Shop A - two workstations with unique Terminal IDs sharing a Cash Drawer
These terminals and cash drawer are together at the front of the shop. Staff process sales from each terminal. Both share a Cash Drawer for receiving customer payments.
The takings in the Cash Drawer are a combination of the transactions from both terminals.
Shop B - two workstations with unique Terminal IDs and individual Cash Drawers
These terminals and cash drawers are in different parts of the building. Each terminal has its own Cash Drawer to receive customer payments - takings in each cash drawer relate only to the Terminal that it is linked to.
