Question 1

What's the difference between an ARM-based and an Intel-based POS system?

Accepted Answer

ARM-based systems (using chips like the RK3399) run Android and are well-suited to cloud-based POS software — they're cheaper, quieter, and consume less power. Intel-based systems run Windows and are necessary if your POS software requires a full desktop OS, or if you need to integrate with Windows-only back-office or accounting systems. For most independent retailers and hospitality businesses using modern SaaS POS platforms, ARM is perfectly sufficient and significantly cheaper.

Question 2

Is a 15.6" screen large enough for a busy till?

Accepted Answer

For the vast majority of retail and hospitality environments, yes — 15.6" at 1920×1080 resolution is the industry standard for a reason. It's large enough to display a full order summary, product images, and payment options simultaneously without overwhelming a standard counter. Only consider stepping up to 21.5" if your staff regularly need to view complex order queues, or if your POS software displays a lot of information on a single screen.

Question 3

Can I use any POS software on these systems?

Accepted Answer

It depends on the operating system. Android-based systems (most Elo, Newland, and Capture units) are compatible with Android POS apps — Square, Lightspeed, Shopify POS, and many others. Windows-based systems (most HP units) run desktop POS software and are compatible with legacy systems. Always confirm OS compatibility with your software provider before purchasing hardware. Some POS software vendors also sell certified hardware bundles, which can simplify the decision.

Question 4

Should I avoid buying a POS system without checking the software licence cost first?

Accepted Answer

Absolutely — this is one of the most common and costly mistakes. The hardware price is just the beginning. Many businesses are surprised to find that their chosen POS software costs as much per year in subscription fees as the terminal itself. Before committing to hardware, confirm the total annual cost of your software licence, any transaction fees, and whether the software vendor charges extra for features like stock management or multi-location support.

Question 5

How important is the IP rating on a POS terminal?

Accepted Answer

Very important if your terminal is near food, drink, or a kitchen environment. An IP54-rated system can handle splashes and dust — adequate for a café counter. IP65 or above is recommended for bar environments or anywhere liquids are regularly handled nearby. Most standard retail POS systems have no IP rating at all, which is fine for a dry shop floor but a risk in hospitality. Check the spec sheet carefully, as manufacturers don't always highlight this prominently.

Question 6

What peripherals do I need alongside a POS system?

Accepted Answer

At minimum, most businesses need a receipt printer, a cash drawer, and a card payment terminal (which is typically provided separately by your payment processor). Depending on your setup, you may also want a barcode scanner and a customer-facing display. Many all-in-one POS systems include a customer display port, but check before assuming. Browse POS system accessories and POS printers to compare prices on the full kit.

Question 7

Which POS system brands offer the best value in 2026?

Accepted Answer

Elo Touch Solutions offers the best balance of price and commercial-grade quality for most businesses — their 15.6" and 21.5" all-in-ones are well-regarded and widely used in UK retail and hospitality. Capture is the strongest option if budget is the primary concern and you're equipping multiple tills. HP is the right choice only if you specifically need Windows, enterprise support, or high-volume processing power — otherwise you're paying a significant premium for specs most businesses won't fully utilise.
