A customer display for POS in Oman is the small screen that faces the shopper at the counter and shows each item, its price and the total to pay. It looks like a minor accessory, but for supermarkets, pharmacies, cafés and mobile shops in Muscat, Seeb and beyond, it builds trust at the moment money changes hands. This guide explains the main types, how they connect to your POS, and what to check before you buy.
Why a customer-facing display matters at the counter
When customers can see what the cashier is entering, there are fewer disputes and fewer mistakes. A shopper who notices a wrong quantity or a missed discount can say so before the receipt is printed, not after. That saves time on refunds and voids, and it protects the cashier too.
- Transparency: the customer sees each item and the running total as it is scanned.
- Faster payment: the amount due and change are visible, so cash and card payments go quicker.
- Fewer errors: wrong prices or double scans are spotted on the spot.
- Professional image: a tidy counter with a customer screen looks organised and modern.
- Promotion space: larger screens can show offers or your logo while the till is idle.
Types of customer displays for shops and restaurants
Pole displays and VFD displays
The classic option is a pole display: a small screen on an adjustable pole beside the POS. Most use VFD (vacuum fluorescent display) technology, with bright green-blue characters that are easy to read even under strong shop lighting. A common format is two lines of 20 characters, which is enough for an item name, price and total. The EASYPOS 2-line x 20-column pole display is a typical example used in grocery shops and mini-marts.
Printer-mounted customer displays
Some receipt printers have a matching display that connects to the printer itself, which keeps cables to a minimum on a small counter. The Epson DM-D30 customer display, for instance, is designed to work with Epson TM-m30 series printers, a neat set-up for cafés and boutiques.
Second screens on all-in-one POS terminals
Many all-in-one POS machines and Android POS terminals come with a built-in second screen on the back. This can show the bill in full colour along with images, offers or a QR code. It is a good fit for restaurants, bakeries and fashion stores that want the display to double as a small advertising screen.
How a customer display connects to your POS
Before buying, check how the display will talk to your computer or terminal. The common connection types are:
- USB: the simplest choice for most modern Windows POS computers.
- Serial (RS-232 / COM port): still common on POS hardware and many business desktops.
- Through the receipt printer: printer-mounted displays receive data from the printer.
- Built-in: second screens on all-in-one terminals need no extra cabling at all.
Just as important is the software. Your POS application has to send the item and total information to the display, so confirm compatibility first. Our team sets up customer displays with the iMPOS POS system and can advise which models fit your existing hardware.
Choosing the right display for your business type
| Business | Suggested display | Why |
|---|---|---|
| Supermarket or mini-mart | VFD pole display | Bright, readable at busy checkouts, low cost per counter |
| Pharmacy | VFD pole or second screen | Clear prices and totals for each customer |
| Café or restaurant | Second screen or printer-mounted display | Shows the order and can display menus or offers |
| Mobile or electronics shop | Colour second screen | Space for promotions and warranty messages |
For restaurants, a customer screen also helps at the order counter, where guests can confirm their items before payment. If you run a food business, see how Riyalo RestoPOS handles counter orders, dine-in and takeaway billing.
Placement and set-up tips
- Position the screen at the customer's eye level and angle it away from the cashier.
- Avoid direct sunlight from shop windows, which can wash out the display.
- Keep cables tidy and secured so the pole cannot be knocked over.
- Test the display with a sample bill, including discounts and VAT, before opening.
- Show amounts in Omani rial with the correct decimal places, and check Arabic text support if you need it.
Frequently asked questions
Does a customer display work with any POS software?
Not always. The POS software must support the display and its connection type. Check with your POS provider before buying, or ask us to confirm compatibility.
Is a VFD display or a second screen better?
A VFD pole display is affordable and very readable for price and total. A second screen costs more but can show the full bill, colours and promotions. Busy grocery counters usually choose VFD; cafés and showrooms often prefer a second screen.
Can I add a customer display to my existing POS counter?
In most cases, yes. If your computer has a free USB or serial port and your software supports it, a pole display can be added in a short visit.
