Quick answer: Nextar publishes real hardware requirements, which is more than most POS vendors do — a 64-bit dual-core processor at 3.4GHz or higher, 8GB of RAM, and Windows 10 Pro or higher. Take the Pro part seriously: Nextar states that “Home versions have internal permission limitations that can cause conflicts with the installation of peripherals such as printers” — and since Nextar prints through the Windows driver, a permissions problem there is a printing problem.
The NB-POS750 (15.6″ 1920×1080, Intel Core i3/i5/i7, 4–8GB, mSATA SSD, Windows 10/11) fits, provided you order it with 8GB and a Pro edition of Windows. Do not economise on either.
The requirements, and what each one is really telling you
| Nextar states | What it means when ordering |
|---|---|
| 3.4GHz or higher, 64-bit, at least two cores | Any current Intel Core generation. Ask your supplier for the exact CPU model, not just “i3” — base clocks vary. |
| 8GB of usable RAM (or more) | Order 8GB, not 4GB. Nextar explicitly notes the OS eats into what is usable. |
| 30GB free for the Nex server, 10GB for a terminal | Any SSD size we ship covers this. SSD over HDD is called out as a real performance difference. |
| Windows 10 minimum, Windows 10 Pro or higher recommended | Specify a Pro edition. See below — this one is not a formality. |
| Not Windows Server, not Windows 7/8/8.1 | Discontinued by Microsoft; Nextar will not guarantee behaviour on them. |
| Customised operating systems not recommended | Avoid stripped-down or “lite” Windows images that some POS suppliers preinstall to save a licence. |
Why Windows Pro is not optional here
This is the point worth reading twice, because it connects two things that look unrelated.
Nextar does not talk to your printer directly. It hands the receipt to the Windows print spooler, which means the printer's Windows driver has to be installed properly and working — we covered this in detail in the Nextar receipt printer guide.
Now put that next to Nextar's own note about Windows editions: Home versions have permission limitations that can cause conflicts with installing peripherals such as printers.
So the two facts compound. On a POS whose printing depends entirely on driver installation, an edition of Windows that can obstruct driver installation is a poor foundation. The licence difference is small; a till that will not print is not.
When you order a terminal, ask what edition is preinstalled and get the answer in writing. Some suppliers ship whatever is cheapest, and “Windows 10” on a quotation does not tell you which edition.
One machine or several?
Nextar supports a server computer with auxiliary terminals on a local network. The specification differs by role:
| Role | Specify |
|---|---|
| Nex server (single till, or the main machine) | 8GB, SSD, 30GB+ free. This one holds the data. |
| Auxiliary terminal | 8GB still recommended, 10GB+ free. Lighter storage is fine. |
Two practical notes for the multi-terminal case, both learned the hard way by people who skipped them:
- Wire the terminals. Ethernet for anything fixed. A shop floor full of people and metal shelving is a poor environment for a database connection over Wi-Fi.
- Give the server a fixed IP address — DHCP reservation in the router, or a static address outside the DHCP pool. If it changes after a power cut, every auxiliary terminal loses the server at the same moment.
It works offline, and that matters
Nextar states that Nex on your computer “was developed to work without the internet”. Internet is needed to download and install it, to validate the subscription, and to sync with the web and mobile apps — but the till itself keeps selling when the connection drops.
For a shop in a region with unreliable broadband, this is a genuine advantage over a purely cloud POS, and it changes what you should protect. With a cloud POS, losing internet can stop trade. With Nextar, losing power stops trade — so put the terminal, the router and the receipt printer on the same UPS and you have covered the realistic failure.
It also means the backup question is yours to answer. Your sales history lives on that machine. Ask Nextar how their backup and sync works on your plan, and make sure someone is actually doing it.
What matters in the terminal itself
- Resolution. Nextar is a desktop application with menus, grids and dialogs. 1920×1080 shows a working screen without paging; 1366×768 does not.
- Projected capacitive touch. Light touch, millions of cycles, wipes clean. Resistive film wears where staff press most.
- SSD. Nextar names it as a real performance difference, and it is.
- Ports. Count them: receipt printer (USB, per Nextar's recommendation), scanner, network, and possibly a label printer. All four at once is common in a small retail shop.
- Heat. A metal chassis handles a hot, un-airconditioned shop better than plastic. Relevant across much of Brazil.

Ordering advice for Nextar — three things, all easy to get wrong:
- 8GB memory, not 4GB. Nextar asks for it by name.
- A Pro edition of Windows, for the printer permissions reason above.
- Ask us for the exact CPU model so you can check it against the 3.4GHz dual-core requirement. We will tell you; a supplier who only says “i3” is not answering the question.
The rest of the till
- Receipt printer for Nextar — the Windows spooler route, and the 72mm print width trap.
- Barcode scanner for Nextar — USB plug-and-play, nothing to configure in Nex.
- Cash drawer for Nextar — wired to the printer; 12V versus 24V.
- Label printer for Nextar — including the compatibility caution Nextar publishes.
Frequently asked questions
What are the minimum requirements for Nextar POS?
Nextar states a 64-bit dual-core processor at 3.4GHz or higher, 8GB of usable RAM, 30GB free for the server (10GB for a terminal), and Windows 10 minimum with Windows 10 Pro or higher recommended. Confirm current figures with Nextar, as requirements change between versions.
Will 4GB of RAM do?
Nextar asks for 8GB and notes that the operating system reduces what is usable. The memory upgrade is a small part of the terminal price and the wrong place to save.
Does it have to be Windows Pro?
Nextar recommends it, and gives a specific reason: Home editions have permission limitations that can conflict with installing peripherals such as printers. Given that Nextar prints through the Windows driver, we would treat Pro as a requirement rather than a recommendation.
Can I run Nextar on Mac, Linux, or an Android POS terminal?
No. Nextar states it is compatible only with Windows computers and is not available for Mac or Linux. Android POS hardware is the wrong platform.
Does Nextar need an internet connection to sell?
No. Nextar states the desktop software was developed to work without internet. Internet is needed for installation, subscription validation, and syncing with the web and mobile apps.
Can I use a second-hand office PC instead?
It will run, and plenty of small shops start that way. What you give up is the touchscreen workflow, the ports laid out for POS peripherals, a chassis built for a counter, and thermals designed for all-day operation in a warm room. If the shop is open six days a week, the arithmetic usually favours purpose-built hardware within the first year.
A note on this guide. The hardware side above — specifying memory and storage for the role, screen resolution for a desktop POS interface, touch technology, network and power planning — is what we know from the products we supply. The Nextar requirements and the Windows edition caution are drawn from Nextar's published documentation and quoted rather than paraphrased; requirements change between versions, so confirm current details with Nextar. If something here did not match your installation, tell us and we will correct this page. We would rather publish something accurate than something impressive.
