POS Hardware Guide

What counts as EPOS hardware?

EPOS hardware means the physical equipment used around an electronic point-of-sale process. Depending on the business, that can include a touchscreen till or terminal, payment equipment, receipt or order printers, barcode scanners and customer-facing self-service devices.

That does not mean every venue needs all of them. A small café taking orders at one counter has a different workflow from a shop scanning packaged products or an attraction serving both pre-booked visitors and walk-ins. Hardware should earn its place by supporting a specific job.

Start with the transaction, not the equipment

Before asking for hardware recommendations, write down three or four common customer journeys. Follow each from the moment somebody is ready to buy until the transaction and any necessary handover are complete.

Hypothetical café example: a customer orders two coffees and lunch at the counter. A colleague enters the order, the customer pays, the preparation team needs the relevant order information and the customer may need a receipt. That sequence tells you more about the required hardware than saying, “We need a café till.”

Hypothetical retail example: a customer brings four packaged products to a checkout. Staff need to identify the correct products, complete the sale and take payment. If those products carry suitable barcodes and the proposed setup supports scanning them, a scanner may have a clear role. A business selling mostly individually configured services may reach a different conclusion.

Include the awkward transactions

Do not map only a perfect sale. Add a customer who changes their mind before payment, an item that cannot be found immediately, a receipt that fails to print or a transaction whose payment status needs checking. Ask what staff should see and which device they use at each point.

This exposes a common purchasing mistake: buying hardware because it appears standard rather than because the business has identified a task for it.

Choose touchscreen tills and terminals for the counter

The staff-facing terminal is often the most visible part of an EPOS setup. Its suitability depends on what employees need to do, where they stand and which peripherals or services the proposed configuration must work with.

Measure the counter rather than judging equipment from a product photograph. Mark the intended position of the display, payment equipment, printer and any scanner. Check that staff still have room for the physical parts of the job: handing over products, serving food or drinks, packing purchases or speaking comfortably with customers.

Also consider sightlines. Staff should not have to turn so far towards a screen that they lose contact with the customer for routine transactions. Cables, power connections and other equipment should have a planned position rather than being solved after installation.

Test the interface with a real order

Ask for a demonstration using transactions similar to yours. Have a colleague enter a normal order, correct an entry using the appropriate process and complete the transaction. The aim is not to count taps for the sake of it; it is to see whether the physical terminal and software make sense together for the people who will use them.

Add printers and scanners where they solve a real task

A receipt printer and barcode scanner can be useful parts of a point-of-sale setup, but neither should be treated as universally essential. Start with the information or action you need and then establish whether the device is the appropriate way to handle it.

For receipt printing, identify which transactions require or use a printed receipt in your operation, where the printer will sit and how staff replace paper. Confirm the exact printer is supported with your proposed EPOS setup rather than assuming any printer with a familiar connection will work.

For scanning, take examples of the products you actually sell to the demonstration. Ask the supplier to show how the proposed scanner and software handle those products. If you use different barcode formats or have unusual product labelling, raise that before purchasing rather than discovering incompatibility at the counter.

Kitchen and service printing needs its own map

If your operation prints orders for a kitchen or another preparation point, decide which information needs to reach each location. A food order, drinks order and customer receipt serve different audiences. Ask the supplier to demonstrate how your proposed setup routes the relevant information instead of assuming that adding another printer automatically creates the workflow you want.

Treat payment equipment as part of the complete setup

Payment is a distinct part of the customer journey and should be discussed using the actual payment arrangement being proposed. Ask which payment terminal or devices are supported, how the staff member starts the payment process and what information passes between the payment and EPOS processes, if any.

Do not assume that every card terminal communicates automatically with every point-of-sale system. If reducing manual amount entry matters to your business, make that a specific requirement and ask for the proposed configuration to be demonstrated.

Test an ordinary payment and ask what staff should do when the outcome is unclear. The correct process depends on the systems and payment provider involved. Employees should know how to establish transaction status using the agreed procedure rather than automatically trying the payment again.

Position payment equipment for the customer

Physical placement matters too. Put customer-operated equipment where it can be presented naturally without stretching cables across the counter or asking customers to reach around other hardware. If the counter serves customers with different accessibility needs, include the practical placement of payment equipment in your layout review.

Decide whether self-service belongs in the journey

A self-service kiosk is not simply another till facing the customer. Introducing one changes who completes parts of the transaction, so start by identifying the task you want customers to perform themselves.

For a food venue, that might be selecting from the available menu and placing an order through a supported self-service process. At a leisure venue, the relevant journey might be different. In either case, test how a first-time customer understands the starting choices, completes the transaction and knows what to do next.

Also plan the exception route. Where does someone go if they cannot find the product or booking they expect? What happens if they abandon the transaction? Who helps when the customer is unsure of the payment outcome? A kiosk should form part of an operating plan rather than becoming an isolated screen staff have to monitor informally.

Check compatibility, layout and support before buying

Hardware selection is partly about individual specifications, but the more important question is whether the proposed components work together in the configuration you are buying. Give the supplier details of any equipment you intend to reuse and ask for compatibility to be confirmed at model level.

Do the same for connections. USB, network, Bluetooth or other connectivity descriptions do not by themselves guarantee that two products will work together in your EPOS environment. Ask how the specific devices are intended to connect and what network, cabling or configuration is required.

Ask what happens when something fails

Record the support route for each important part of the setup. Staff should know who to contact when a till will not operate normally, a printer stops responding or a peripheral cannot be used. Where equipment comes from different providers, establish which supplier handles which problem.

Maintenance advice should come from the documentation for the exact equipment involved. Avoid generic cleaning or repair routines copied from another model. Train staff in the routine actions they are expected to perform and make the escalation point clear when those steps do not solve the issue.

Build your own EPOS hardware list

There is no universal bundle containing everything every business needs. A better list comes from the customer journeys you mapped at the beginning. For each device, write down the task it performs. If you cannot complete that sentence, ask whether the equipment is genuinely required.

EPOS hardware planning checklist

• Map several common transactions from customer request to completion.
• Include at least one correction, exception or failed peripheral scenario.
• Count the staff service positions that genuinely need point-of-sale access.
• Measure each counter before choosing screen and peripheral positions.
• Identify which transactions need customer receipt printing.
• Test real product barcodes if scanners form part of the proposed setup.
• Map where food or other preparation orders need to appear.
• Confirm the exact hardware models are supported with the chosen EPOS software.
• Confirm how payment equipment fits into the proposed transaction process.
• Check power, network and cable requirements at the installation locations.
• Test self-service with a first-time customer scenario if kiosks are being considered.
• Ask what staff should do when each important device is unavailable.
• Record warranty, support and replacement arrangements offered with the proposed equipment.
• Use current supplier or manufacturer specifications when comparing models.

Frequently asked questions

What is EPOS hardware?

EPOS hardware is the physical equipment used as part of an electronic point-of-sale setup. Depending on the business, it can include staff terminals, payment equipment, printers, scanners and self-service devices.

Does every small business need a till, scanner and receipt printer?

No single hardware list suits every small business. A scanner makes sense where supported product barcodes form part of the checkout process, while a printer is relevant where the business needs printed output. Choose each device for an identified task and confirm compatibility with the proposed system.

Can I reuse EPOS hardware I already own?

Possibly, but compatibility should be checked for the exact model and proposed configuration. Give the supplier model details, connection information and any other requested specifications before relying on existing equipment.

Should I choose EPOS software or hardware first?

It is usually more useful to define the operational requirements first and assess the complete setup together. Software and hardware depend on each other: a device is only useful if the chosen system supports it in the way your workflow requires.

How should I compare hardware proposals?

Ask suppliers to demonstrate the same realistic transactions, then compare compatibility, physical layout, required connections, customer and staff workflow, support arrangements and current model specifications. This gives you a more meaningful comparison than looking at device specifications in isolation.
