Key Takeaways
- POS hardware breaks into a few core categories: terminals, card readers, printers, scanners, cash drawers and displays. You don’t need all of them, only what matches how you actually take payments.
- Choosing between a proprietary terminal and a tablet-based setup matters more than any single peripheral, because it decides how locked in you are if you ever switch providers.
- A UK-specific deadline most hardware guides miss: older card machines and EPOS systems connected via analogue phone lines need checking, because the UK’s PSTN network switches off by 31 January 2027.
- Barcode scanning for retail should follow GS1 standards, the same ones used across UK and global retail, so products scan correctly everywhere, not just on your own till.
- A bundled cloud POS with hardware, software and support included avoids most of the compatibility headaches of assembling equipment from several vendors yourself.
Open five POS provider websites and you’ll find five different hardware line-ups, each described as essential. A terminal here, a “smart reader” there, a kiosk being sold as a must-have. It’s not that any of them are wrong. It’s that nobody’s explaining which pieces actually apply to your business.
This guide breaks POS hardware down by what each piece actually does, what you genuinely need based on how you take payments, and one UK-specific deadline that catches a lot of businesses off guard.
What Counts as POS Hardware?
POS hardware is the physical equipment your point-of-sale software runs on and connects to. It falls into a handful of categories:
- Terminals or tablets that run the POS software itself
- Card readers that process payments
- Printers for receipts and, in food service, kitchen tickets
- Cash drawers for handling cash securely
- Barcode scanners for retail checkout
- Customer-facing displays for order totals and tip prompts
Most small businesses use some combination of these, not all of them. A cafe might need a terminal, a card reader and a receipt printer. A retail shop adds a barcode scanner and cash drawer. A restaurant adds a kitchen printer or kitchen display system on top of that. Working out which category matters starts with looking at how transactions actually happen in your business, not with a shopping list.
POS Terminals: All-in-One vs Tablet-Based
There are two broad approaches to the terminal itself.
Proprietary all-in-one terminals combine a screen, card reader and sometimes a printer into one purpose-built device. They’re simple to set up and built for daily commercial use, but they’re usually locked to one POS platform. If you switch providers later, the hardware often can’t come with you.
Tablet-based setups run POS software on a standard tablet, paired with a stand and separate peripherals. They’re cheaper to start with and the tablet has some resale or repurposing value if you switch systems, but you’ll need to add card readers, printers and stands separately, and confirm each one is compatible with your software.
Neither approach is universally better. The right choice depends on whether you’re likely to change providers in the next few years and how much you value a single, integrated unit versus flexibility.
Card Readers and Payment Terminals
Card readers fall into two types. Mobile card readers are small, portable, and connect to a phone or tablet, ideal for market stalls, pop-ups and anywhere payments happen away from a fixed counter. Countertop card readers sit at a fixed till and typically support chip, contactless and sometimes PIN entry for larger transactions.
Whichever type you choose, contactless and chip support are now the baseline expectation in the UK, not an upgrade. If you’re buying used or older equipment, confirm NFC contactless support specifically before committing, since some older devices predate it entirely.
Receipt Printers, Kitchen Printers and KDS
Receipt printers are almost always thermal: fast, quiet and ink-free. Kitchens are the exception. Heat from cooking equipment can fade thermal paper, so many kitchens still use impact printers or, increasingly, a kitchen display system (KDS) that replaces paper tickets with a digital screen showing live orders.
A KDS isn’t just a nicer version of a printer. It removes illegible handwriting and lost tickets, lets kitchen staff reprioritise orders on the fly, and gives you timing data you can use to spot bottlenecks during a busy service. For any food business running more than a handful of covers a day, it tends to pay for itself in reduced chaos alone.
Cash Drawers, Barcode Scanners and Customer Displays
A few smaller pieces round out most setups:
- Cash drawers open automatically on a cash sale and are worth keeping even in a mostly card-based business, since a secure, organised drawer still matters for the cash transactions that do happen.
- Barcode scanners speed up retail checkout and cut manual entry errors. If you’re assigning your own product barcodes, following the GS1 UK standards means your products scan correctly not just at your own till, but anywhere else that uses the same standard, including online marketplaces.
- Customer-facing displays show the running total and tip prompts. For businesses where tipping matters, a visible prompt at the point of payment tends to outperform a paper receipt alone.
One Thing Most Guides Miss: The UK’s PSTN Switch-Off
Here’s a detail that’s genuinely easy to miss if you’re reading a US-written hardware guide, because it doesn’t apply anywhere else.
The UK’s old analogue telephone network, known as the PSTN, is being switched off nationwide by 31 January 2027. BT Business confirms this affects more than phone calls: alarms, door entry systems, CCTV and EPOS machines that still connect through a traditional analogue line will need to move to a fully digital, internet-based connection before the switch-off completes.
If your business still runs an older card machine or till system that dials out over a phone line rather than the internet, this is worth checking now rather than in early 2027. A modern cloud POS running over broadband or 4G sidesteps the issue entirely, but it’s exactly the kind of hidden dependency that’s easy to overlook until a line stops working.
Buying, Leasing or Bundling: What Actually Makes Sense for a Small Business
There are three ways to acquire POS hardware, and each suits a different situation:
- Buying outright costs more upfront but avoids ongoing payments and contract lock-in. Over the life of the equipment, it’s usually the cheapest route.
- Leasing lowers the upfront cost but almost always costs more in total, and can tie you to a provider for longer than you’d otherwise choose. Read the end-of-term terms carefully, since some leases don’t transfer ownership even after years of payments.
- Bundled packages combine a terminal, card reader and key peripherals at one price, with compatibility already sorted for you. For most small UK businesses, this is the easiest starting point, since it removes the research needed to assemble a working hardware stack from multiple vendors.
Matching Hardware to Your Business Type
The hardware conversation gets a lot simpler once you stop treating it as a separate purchase from your POS software.
Blue Lotus X ships hardware, software and support as one package rather than a checklist you assemble yourself. A countertop POS covers a fixed till setup for retail or a cafe counter, while a self-service kiosk suits a quick-service operation that wants customers ordering and paying without a queue at the till. Both connect to the same back-end reporting and inventory system, so there’s no separate compatibility check to run.
Whether you’re setting up a single restaurant floor or a small retail counter, the goal is the same: hardware that matches how you actually take payments, without becoming a second project on top of choosing your POS software.
FAQ
What hardware do I actually need for a small POS setup?
At minimum, most small businesses need a terminal or tablet, a card reader, and a receipt printer. Cash drawers, barcode scanners and kitchen displays are added based on whether you handle cash, sell barcoded products, or run a kitchen.
Should I buy a proprietary terminal or a tablet-based POS?
A proprietary terminal is simpler to set up but usually locks you to one POS platform. A tablet-based setup costs less upfront and offers more flexibility if you switch providers, but requires separate peripherals and compatibility checks.
Does my card machine need to support contactless payments?
Yes, in practice. Contactless and chip support are now the baseline expectation for UK card payments. If you’re buying used or older equipment, confirm NFC contactless support before purchasing, since not all older devices include it.
What is the UK PSTN switch-off, and does it affect my POS hardware?
The UK’s analogue phone network is being switched off by 31 January 2027. Older card machines and EPOS systems that connect via a traditional phone line, rather than the internet, may be affected and should be checked for compatibility ahead of the deadline.
Is it cheaper to buy or lease POS hardware?
Buying outright is usually cheaper over the life of the equipment, since leasing spreads the cost but almost always totals more and can include long-term contract commitments.
