Quick answer:
A POS terminal is the physical hardware that takes a payment at checkout. It reads a customer’s card by chip, tap or swipe, sends the transaction for authorization, and returns an approval or decline. The device can be a wired countertop unit, a handheld reader paired to a phone, or a touchscreen smart terminal with its own printer.
Terminal is not a synonym for POS system. The terminal takes the payment; the system around it manages inventory, receipts, staff logins and reporting. Current standalone terminals range from $59 for a Bluetooth card reader to $349 for Shopify’s smart terminal.
Hardware is the part of a point-of-sale purchase that is expensive to undo. You can switch software plans in an afternoon, but a counter full of the wrong devices sits there for years.
Terminal choice also decides whether you can take payment on the shop floor, whether a queue can be split at peak hours, and who covers the loss when a fraudulent chip card is presented. Here is what the hardware actually does, what the current models cost, and how to choose between them.
What is a POS Terminal? The Basics
When a customer pays by card in your store, the piece of equipment they tap or insert their card into is the POS terminal. It reads the card, encrypts the data, and sends it to the issuing bank for approval. The terminal authorizes payments; it does not run your store.
Everything else you think of as “the POS”, the product catalog, the stock counts, the end-of-day report, sits in the software layer described in the entry on a full POS system.
You will hear the same device called a payment terminal, credit card terminal, card machine or PIN pad terminal. The labels are used loosely, but the job is identical. What separates one terminal from another is not the payment flow itself. It is where the device can go, whether it has its own screen or borrows one from a phone, how it prints, and how it connects to your store’s network.
POS Terminal vs POS System
The distinction matters because vendors quote the two things in the same breath. A terminal carries a one-time price. A system usually carries a monthly one.
A terminal is one component of a system, not a smaller version of it. A single store can run several terminals on one system, and a market stall can run a single terminal with almost no system behind it.
| Layer | What it does | What you pay |
|---|---|---|
| POS terminal | Reads the card, requests authorization, prints or sends the receipt | One-time hardware price, plus a per-transaction processing rate |
| POS software | Catalog, stock levels, discounts, staff permissions, sales reporting | Usually a monthly subscription per location or per register |
| Card reader | Reads the card only, with no screen or software of its own | One-time price, lower than a terminal |
The middle row is the one retailers underestimate. A cheap terminal attached to expensive software is still an expensive checkout, which is why the types of POS systems available for retail are worth reading alongside any hardware quote.
The Main Types of POS Terminal
Five hardware categories cover almost everything you will be sold. They differ mainly in mobility and in how much of the checkout they can handle alone.
| Type | What it is | Who it suits |
|---|---|---|
| Countertop terminal | Stationary, usually wired to power and network, parked at a fixed till | Stores with a settled cash wrap and steady daily volume |
| Mobile or handheld terminal | Battery powered, connects over Bluetooth, Wi-Fi or cellular | Floor staff, markets, pop-ups, curbside handover |
| Smart terminal | Self-contained touchscreen device running apps, often with a built-in printer | Retailers who want one device to be the whole checkout |
| PIN pad | Customer-facing keypad and screen, standalone or attached to a register | Grocers and high-volume stores where the cashier keeps a separate screen |
| Self-service kiosk | Unattended terminal the customer operates alone | Convenience, quick service, and stores fighting queue length |
The line between a handheld terminal and a card reader is worth holding onto. A reader is an accessory with no screen and no software of its own, so it needs a phone or tablet to be useful, which is the setup covered under mobile POS.
Smart terminals blur the categories deliberately. Many of them are portable, print receipts, prompt for tips and run a full sales app, which is why they now sell as a first and only device for small stores. A self-checkout kiosk sits at the other end, taking the staff member out of the transaction entirely.
What Is Inside a POS Terminal
Terminals look like plain plastic boxes, but the internals are where certification and cost come from.
- Card reading paths: a chip slot for contact payments, an NFC antenna for tap, and on older units a magnetic stripe track. A terminal that reads chip and tap keeps your store on the right side of the EMV rules.
- Secure element: tamper-resistant hardware that encrypts card data at the moment of capture, so plain card numbers never travel across your store network.
- Connectivity: ethernet or Wi-Fi on countertop units, Bluetooth and cellular on portable ones. Connectivity is the single most common cause of a terminal that “stops working”.
- Display and printer: a smart terminal carries both, a PIN pad carries a small display only, and a plain reader carries neither.
Payment hardware sold in the US is expected to hold PCI PTS approval, the security approval scheme for PIN entry devices. Buying an uncertified device from an unfamiliar reseller is one of the few genuinely dangerous shortcuts in retail hardware.
What POS Terminals Cost in 2026
Published hardware prices from the major direct-sale providers, current as of August 2026:
- Square Terminal, $299 one time, or $27 a month for 12 months on Square’s financing, with no monthly software fee on the basic plan.
- Square Reader for Contactless and Chip, $59, a Bluetooth reader that pairs with your phone or tablet.
- Shopify POS Terminal, $349, a handheld smart terminal bundled with a Terminal Dock.
- Shopify Eddy Tablet Stand, $149, the counter stand for an iPad-based checkout.
- SumUp readers from $99, at an in-person rate of 2.6% plus 10 cents.
- PayPal Reader from $79 and PayPal Terminal from $199, the current US names for the hardware sold as Zettle elsewhere.
Square’s in-person rate across its hardware is 2.6% plus 15 cents per tap, dip or swipe, the number that ends up mattering more than the device price. Clover hardware is a different case: it is sold through payment processors and resellers rather than direct, so the price you are quoted depends on the deal and the contract attached to it. The Clover POS review covers how that channel works.
One current change is worth knowing before comparing Shopify hardware. Shopify POS Go has been discontinued, and it has two different successors that are easy to confuse. For handheld selling, Shopify’s migration guidance points to the Verifone Victa Mobile at $399. For countertop use, the POS Go hardware itself was rebranded: the $349 Shopify POS Terminal pairs the reader that used to be called POS Go with its dock.
Existing POS Go units keep mobile selling until May 26, 2027, after which they switch permanently to countertop terminal mode and lose the built-in barcode scanner, which only works in mobile mode. Shopify states there is no trade-in program for the device, according to Shopify’s own help documentation. If you are weighing a secondhand POS Go against the Shopify POS hardware guide, price in that sunset date.
Worked Example: Kitting Out a Two-Till Shop
A homeware shop needs two fixed checkouts plus one device staff can carry to a customer on the floor. Two realistic bills of materials:
| Build | Items | Hardware total |
|---|---|---|
| Square route | 2 x Square Terminal at $299, 1 x Square Reader at $59 | $657 |
| Shopify route | 2 x Shopify POS Terminal at $349, 1 x Eddy Tablet Stand at $149 | $847 |
The gap between the two builds is $190, once. Now place processing alongside it. At Square’s 2.6% plus 15 cents, a shop turning over $18,000 a month in card sales across 900 transactions pays $468 in percentage fees and $135 in per-transaction fees, so $603 a month, or $7,236 across a year.
So the entire hardware decision is a one-time $190 set against $7,236 of processing in the same twelve months. That is the takeaway: pick the terminal that fits how your store actually sells, then negotiate the rate, because the rate is where the money goes. For a wider cost picture, compare against how much a cash register costs.
Choosing a Terminal for Your Store
Four questions settle most terminal decisions.
- Where does payment happen? A fixed counter points to a countertop or smart terminal. Floor selling, markets and curbside point to handheld hardware.
- Does it read chip and tap? Anything that only reads a magnetic stripe leaves your store carrying fraud losses it does not have to carry.
- Does it print? A built-in printer removes one cable, one power socket and one thing that fails on a Saturday.
- Will the fleet match? One model across every till cuts training time and makes a broken unit a swap rather than a project.
Beyond that, buy the device the software you have already chosen supports properly. The Square Terminal review and the complete guide to Square POS hardware are useful for seeing how a single vendor’s devices are meant to fit together before you commit a counter to them.
