Overview of POS terminals for a retail store in 2025-2026

The POS terminal is the heart of an automated retail outlet. The right choice determines service speed, cashier convenience, and reliability. We look at which POS terminals are relevant in 2025-2026 and what to pay attention to when buying, so you don't overpay or regret it.

What is a POS terminal

A POS terminal (point of sale) is the cashier's workstation where a sale is processed. In the modern sense, it is a computer with a touchscreen, to which a fiscal printer or software fiscal registrar, barcode scanner, cash drawer, bank terminal, and scales are connected. It is important not to confuse a POS terminal as a cashier workstation with a bank POS terminal for card payments — these are different devices.

Types of POS terminals

All-in-one units

The most popular format: screen, computer, and often printer in a single housing. They save space, look neat, and are easy to maintain. Ideal for shops, pharmacies, and coffee shops with a fixed checkout point.

Modular (PC-based)

A separate system unit, monitor, and peripherals. Flexible in upgrades and repairs, suitable for large shops and supermarkets that need power and multiple checkouts.

Mobile POS (mPOS)

A tablet or specialized terminal with its own battery. Indispensable for off-site sales, delivery, takeaway coffee shops, and operation during power outages.

Tablet checkouts

A tablet on a stand with a checkout application. A budget-friendly and compact solution for small outlets and the service sector.

What to pay attention to when choosing

1. Customer flow. For high traffic — a productive processor and a quality touchscreen that withstands thousands of touches per day.
2. Compatibility with software fiscal registrars. The terminal must work correctly with your software fiscal registrar and fiscal printer.
3. Ports and peripherals. Enough USB and COM ports for a scanner, drawer, scales, and customer display.
4. Screen quality. A capacitive touchscreen is more convenient than a resistive one; an anti-glare coating matters in bright light.
5. Reliability and warranty. A POS runs 10-12 hours every day, so reliability is critical.
6. Autonomy. Its own battery or the ability to run from a UPS is a plus during blackouts.
7. Operating system. Windows, Android, or a specialized OS — depends on the checkout software.

Peripherals you can't do without

• Fiscal printer or software fiscal registrar — for printing receipts and transmitting data to the State Tax Service.
• Barcode scanner — speeds up ringing up goods and eliminates errors.
• Cash drawer — for securely storing cash.
• Bank terminal — for card payments.
• Customer display — shows the amount, mandatory in many formats.
• Scales — for shops with weighed goods.

Price categories

Budget segment

Tablet checkouts and simple mPOS. Suitable for small businesses, sole proprietors, and outlets with low traffic. Minimal investment, basic functionality, quick start.

Mid-range segment

Quality all-in-one units with a good screen and sufficient performance. The optimal price-to-reliability ratio for most shops, pharmacies, and coffee shops.

Premium segment

Powerful all-in-one units and modular systems with extended peripherals, customer displays, and metal housings. For supermarkets, chains, and outlets with intense traffic.

POS for different types of business

The right terminal depends not only on the budget but also on the specifics of the outlet:

• Grocery store. You need a scanner, scales with label printing, a customer display, and a fast all-in-one unit for queues.
• Pharmacy. Accuracy, integration with medication accounting, and all-day reliability matter.
• Clothing and footwear store. An all-in-one unit with a scanner is enough, with a focus on size handling and a loyalty program.
• Takeaway coffee shop. A compact tablet checkout or mPOS with its own battery.
• Off-site sales and delivery. A mobile POS with built-in connectivity and autonomy.

New or used equipment

The temptation to save on a used POS is understandable but carries risks: no warranty, a worn touchscreen, incompatibility with modern software and software fiscal registrars. For an outlet your income depends on, it is safer to buy new equipment with a warranty and service support. A used option is justified only as a backup checkout.

Checkout software is no less important than hardware

Even the best terminal is useless without convenient checkout software. Pay attention to compatibility with your BAS/1C accounting, the availability of a loyalty module, support for promotions and discounts, cashier speed, and integration with software fiscal registrars. Often it is the software that determines which POS will suit you.

Common mistakes when buying

• Saving on a terminal for a high-traffic outlet — a weak POS slows down the queue.
• Buying without considering compatibility with software fiscal registrars and checkout software.
• A shortage of ports for all the needed peripherals.
• Ignoring autonomy in conditions of unstable power supply.
