How Does a Cash Drawer Work?
A cash drawer is a secure container typically used at the point of sale (POS) for storing cash, coins, and receipts. It connects to a POS system, opening automatically when a transaction is completed to allow cash handling and closing securely between uses. Understanding how a cash drawer operates optimizes workflow and enhances security in retail and hospitality businesses.
What Are the Components of a Cash Drawer?
Cash drawers commonly have a robust metal casing, coin and bill compartments, a lock for manual operation, and an interface cable (usually RJ11 or RJ12) for connecting to the POS receipt printer or terminal. Some drawers feature advanced mechanisms like reinforced locking and notification sensors.
How Does a Cash Drawer Connect to the POS System?
Cash drawers connect to POS terminals primarily via receipt printers using an interface cable. When a sale transaction is completed, the POS sends a signal through the printer to trigger the drawer to open. USB or Bluetooth-enabled cash drawers are also increasingly common for direct computer integration.
How Does the Opening and Locking Mechanism Work?
The POS software sends an electrical signal to the cash drawer's solenoid, which releases the latch and opens the drawer. Most drawers can also be locked manually for extra security or during closing hours, preventing unauthorized access.
What Security Features Help Prevent Theft?
High-quality cash drawers like those used with FAVORPOS offer lock-and-key systems, reinforced metal construction, alarm or notification functions when forced open, and audit trails through the POS. Access control via software permissions is another standard security solution.
How Can Common Issues with Cash Drawers Be Resolved?
If a cash drawer fails to open, check cable connections, printer status, software configuration, and ensure the solenoid is functioning. For stuck drawers, gently use the emergency release or manual key. Regular cleaning and maintenance prevent dust build-up and mechanical jams.
