Taking orders at the Register
Compose orders at the Muin POS register with keyboard shortcuts, barcode scanning, cash and card payments, and digital receipts for fast checkout.
The Register is where cashiers compose orders, take payment, and issue receipts. It’s designed for single-screen touch use but fully keyboard-accessible.
Register layout
- Left — product picker with search, category filter, and barcode input
- Right — cart with per-line quantity controls and discounts
- Bottom right — totals (subtotal, discount, tax, tip), customer capture, PAY button
Keyboard shortcuts
| Key | Action |
|---|---|
| Enter | Add focused product to cart |
| F1 | Open payment panel |
| Esc | Clear cart (with confirm) |
| Ctrl+D | Open discount modal |
| F9 | Focus barcode scanner |
Barcode scanning
Plug a USB HID barcode scanner (keyboard-wedge mode) into the terminal. Press F9 to focus the barcode field. Scanned codes auto-submit on Enter and add the matching product to the cart. If no product matches the barcode, a “not found” toast appears.
Payment methods
- Cash — enter the amount received; the system shows change due. Quick presets for $5, $10, $20, $50, $100, and Exact.
- Card — process the payment on your standalone terminal, then enter the reference number from its receipt. Muin records the transaction.
- Split — combine cash + card; both amounts must sum to the total.
Receipt
After payment, capture the customer’s email or phone to send a digital receipt. The order is then sent to the Kitchen display for prep (if preparation status is enabled on any line item).
Handling mistakes
- Use Void for orders that haven’t been paid yet — restores inventory.
- Use Refund (from the Orders manager view) for completed orders.
See Refunds & voids for the full refund workflow.
