Cash drawer
A cash drawer is a box that opens electrically when a cash sale is completed. It usually connects to an RJ11 port on the receipt printer, and the system opens it with an ESC/POS command.

In RAWA the drawer can open automatically on cash payment, or manually with permission, with every open logged in the shift report.
How the drawer opens
Most drawers connect to the printer with an RJ11/RJ12 cable, and on a cash payment the printer sends an electrical pulse that opens it. So the drawer needs no separate connection to the computer and opens with the cash receipt only.
Drawer discipline and control
An unmonitored drawer is a source of silent loss. Every “no sale” opening should be logged, and the cash counted at shift end compared with what the system expects.
- Tie drawer opening to cash payments only
- Require a reason for any opening without a sale
- Count cash at the close of every shift
- Give each cashier their own drawer in a separate shift

Do I need a USB drawer?
Usually no; drawers connect to the printer, and the printer to the system over the network or USB.
