POS Hardware Guide: Terminals, Tablets, Card Readers & More

Types of POS hardware setups

Before diving into individual components, it helps to understand the broad categories of POS hardware setups, because the right configuration depends on how and where you do business. There are three types of POS hardware setups:

1. Countertop and fixed setups are the traditional configuration: a terminal or tablet mounted at a register, connected to a card reader, receipt printer and cash drawer. This is the standard for brick-and-mortar retail stores, restaurants with a fixed checkout counter, salons and similar businesses where transactions happen at a dedicated station.
2. Mobile setups pair a smartphone or tablet with a portable Bluetooth card reader. These are built for businesses that don’t operate from a fixed location — think food trucks, farmers markets, pop-up shops, field service providers and delivery operations. Mobile setups are lightweight, battery-powered, and designed to work over cellular or Wi-Fi connections.
3. Self-service kiosks are customer-facing terminals where customers place their own orders and pay without interacting with a cashier. These have become increasingly common in quick-service restaurants, fast-casual dining and some retail environments. Kiosks typically use a large touchscreen mounted on a floor stand or wall mount, paired with an integrated card reader.

Many businesses use a combination of these setups. A restaurant might have fixed registers at the host stand and bar, mobile tablets for tableside ordering and a self-service kiosk for takeout orders. A retailer might use countertop terminals for the main checkout and mobile readers for line-busting during peak hours. Your hardware plan should reflect your actual workflow, not just the primary checkout scenario.

POS hardware guide

Below, learn about the essential equipment that makes up POS hardware, from all-in-one terminals to peripherals like barcode scanners and customer-facing displays.

POS terminals

POS terminals are all-in-one proprietary devices designed specifically for point-of-sale use. Products like the Clover Station, Square Register and Toast terminal fall into this category. These units typically combine a touchscreen display, a built-in or tightly integrated card reader, and sometimes a built-in receipt printer into a single countertop unit.

The primary advantage of a dedicated POS terminal is simplicity. Because the hardware is purpose-built for the vendor’s software platform, there are minimal compatibility concerns. Setup is straightforward, the devices are designed for the rigors of daily commercial use, and the countertop footprint is typically clean and compact. Many terminals also include a customer-facing screen for order review and tip prompting.

The trade-off is ecosystem lock-in. Proprietary terminals are designed to work exclusively with their associated POS platform. If you decide to switch from Clover to Square, for example, your Clover hardware won’t be compatible with the Square software. This is an important consideration for businesses that may want to change POS providers in the future. Proprietary terminals also tend to carry a higher upfront cost than tablet-based alternatives.

Typical price range: $300 to $2,000 or more, per terminal, depending on the model and included features.

Tablets and tablet stands

Many of the most popular POS platforms — including Square, Lightspeed, Shopify and Toast — are designed to run on standard iPads or Android tablets. Using a tablet as your POS terminal offers a lower entry cost, a familiar user interface for staff and the flexibility to repurpose the tablet if you change systems. Android support is limited on POS platforms, so confirm compatibility with your chosen software before purchasing.

To convert a tablet into a functional register, you’ll pair it with a stand or commercial enclosure. Basic swivel stands typically cost $30 to $100, while commercial-grade enclosures with integrated card reader mounts, cable management and theft deterrence range from $100 to $400, with premium kiosk-style setups exceeding that range. The enclosure you choose should be sturdy enough to handle daily use, position the screen at a comfortable angle for your staff, and ideally allow the tablet to rotate toward the customer for signature or tip prompting.

The main limitation of tablet-based setups is that they require more peripheral hardware to build a complete system. Unlike an all-in-one terminal that may include a built-in card reader and receipt printer, a tablet requires those components to be added separately. In high-volume environments, tablets may also be less durable than purpose-built commercial hardware, though a quality enclosure helps mitigate this.

Typical price range: $300 to $1,000 for iPads; $100 to $400 or more for Android tablets.

Card readers

There are two main types of card readers.

Mobile card readers

Mobile card readers are small, portable devices that connect to a phone or tablet via Bluetooth (or in older models, the audio jack). They accept chip (EMV), contactless/NFC (tap) and sometimes magstripe payments. These readers are often provided free or at very low cost by the POS provider as an incentive to use their platform, since the provider earns revenue from the processing fees on every transaction.

Mobile readers are ideal for businesses that need portability: market vendors, food truck operators, pop-up retailers, freelance service providers and anyone who needs to accept payments away from a fixed location. They’re also useful as a backup reader for brick-and-mortar businesses in case the primary terminal malfunctions.

Typical price range: $0-$100, with basic magstripe readers often free and Bluetooth-enabled chip and contactless readers typically costing $30 to $80. 

Countertop card readers

Countertop card readers are designed for fixed checkout locations. They sit on the counter facing the customer, who inserts their chip card, taps their contactless card or phone, or swipes their magstripe. Many countertop readers also support PIN entry for debit transactions. These readers connect to the POS terminal via USB, Bluetooth or Wi-Fi, depending on the model.

Typical price range: $50 to $400 or more, depending on build quality, connectivity options, and whether the device includes a display screen and software-driven features. 

Accepting contactless payments — including tap-to-pay cards, Apple Pay, Google Pay and Samsung Pay — is now a baseline expectation in most markets. Customers increasingly prefer the speed and convenience of tapping their card or phone rather than inserting a chip card and waiting for the transaction to process. Virtually all current-generation card readers support NFC contactless payments, but if you’re purchasing used or older-model equipment, verify NFC capability before buying.

Receipt printers

Receipt printers come in two main types. 

1. Thermal printers are the most common in POS environments — they’re fast, quiet, and require no ink or toner (they use heat-sensitive thermal paper). 
2. Impact printers use ink ribbons and are louder, but they’re necessary in kitchen environments where heat from cooking equipment can cause thermal paper to darken or fade, making printed orders unreadable.

Connection options include USB, Bluetooth, Wi-Fi and Ethernet. Match the connection type to your POS system’s supported interfaces and your physical setup. Wi-Fi and Bluetooth printers offer more flexibility in placement since they don’t require a cable run to the terminal, but wired connections (USB or Ethernet) tend to be more reliable in high-volume environments.

Many businesses are reducing their reliance on printed receipts by offering emailed or texted receipts, but most still need at least one receipt printer for handling returns, printing kitchen orders or accommodating customers who prefer paper.

Typical price range: $100 to $500 or more, depending on features and durability. 

Cash drawers

A cash drawer is a straightforward piece of hardware that opens automatically when a cash transaction is processed through the POS system. It connects to the system through the receipt printer via an RJ12 cable — not directly to the POS terminal. When the POS sends a print command for a cash transaction receipt, the printer triggers the drawer to open.

Standard-size drawers fit under most counters and offer full bill and coin compartments. Compact models are available for tight spaces or mobile setups. Even businesses that process the vast majority of their transactions via credit card typically keep a cash drawer on hand. Cash transactions, while declining in share, still occur, and having a secure, organized drawer is necessary for starting-till management and end-of-day reconciliation.

Typical price range: $50 to $250, depending on durability and integration features.

Barcode scanners

Barcode scanners speed up checkout and reduce manual entry errors by reading product barcodes and automatically adding the corresponding item to the transaction. Handheld scanners are the most common type and are available in wired (USB) and wireless (Bluetooth) configurations. Presentation or countertop scanners are hands-free devices mounted at the checkout station — the cashier or customer passes the item over the scanner, similar to a grocery store self-checkout.

When choosing a scanner, consider whether you need 1D or 2D scanning capability. Standard 1D scanners read traditional barcodes (UPC, EAN). 2D scanners can also read QR codes and codes displayed on smartphone screens, which is useful if you accept mobile coupons, digital loyalty cards or ticket-based entry. Barcode scanners are essential for retail businesses with barcoded inventory, but are generally not needed by restaurants, salons or service-based businesses.

Typical price range: $50 to $300 or more, depending on scanning capability and durability. 

Kitchen display systems

A kitchen display system (KDS) replaces paper ticket printers in a restaurant kitchen with a digital screen that shows incoming orders in real time. Orders placed at the register or through online ordering appear on the KDS immediately. Kitchen staff can view order details, track how long each order has been in the queue, prioritize items and mark orders as complete — all without handling paper tickets.

The benefits are significant for any food-service operation. A KDS eliminates the problems associated with paper tickets: illegible handwriting, lost or misplaced tickets, and the inability to easily reprioritize the queue. Digital displays also provide timing data that helps kitchen managers identify bottlenecks and improve performance over time.

KDS hardware typically consists of a commercial-grade display (or a standard tablet running KDS software) mounted in the kitchen. Not every POS platform supports a KDS integration, so confirm compatibility before purchasing. Some systems use proprietary KDS hardware, while others allow you to run KDS software on any compatible tablet.

Typical price range: $150 to $900 or more per screen, depending on size, durability, and whether the unit is a basic display or a full commercial-grade touchscreen KDS terminal.  

Customer-facing displays

Customer-facing displays are screens positioned toward the customer during checkout. They serve multiple functions: showing the itemized order total for transparency, presenting tip prompts, displaying marketing messages or loyalty program information, and allowing the customer to confirm their order before payment.

Some POS terminals include a built-in customer-facing screen. Others offer it as an add-on display that mounts on the existing terminal stand. Customer-facing displays have become particularly important for businesses that rely on tips. The visual tip prompt on a customer-facing screen has been shown to increase tip rates compared to paper receipts alone, making the display a revenue-generating investment for restaurants, cafes and service businesses.

Typical price range: $75 to $500 or more for standalone displays, depending on features and configuration.

Networking and connectivity hardware

Cloud-based POS systems depend on a reliable internet connection, which makes your networking infrastructure an important part of the hardware equation. A quality router and modem are the foundation. For your primary POS terminal, a hardwired Ethernet connection is more stable and reliable than Wi-Fi, particularly during peak transaction periods when network congestion could cause processing delays. Wi-Fi is acceptable for mobile devices and secondary terminals.

Some POS systems offer an offline mode that allows the terminal to continue processing transactions even when the internet connection drops. Offline transactions are stored locally and sync to the cloud once connectivity is restored. This feature is important for businesses in areas with unreliable internet service, as well as for mobile and outdoor operations where connectivity is inherently variable. If offline capability is critical to your business, confirm that your POS platform supports it and understand any limitations. Some offline modes accept only certain payment types or restrict the number of transactions that can be processed before syncing.

For businesses where losing the ability to process payments would be catastrophic, consider maintaining a backup mobile hotspot you can switch to if your primary internet connection goes down. The cost of a basic cellular hotspot plan is minimal compared to the revenue lost during an outage.

Accessories and add-ons

Beyond the core hardware components detailed above, several accessories may be relevant depending on your business type. Tablet mounts — countertop, wall-mount or floor-stand configurations — are needed for any tablet-based setup and for self-service kiosks. Scales are necessary for businesses that sell by weight, such as delis, bakeries, candy shops and produce markets. Label printers are used in retail for price tags and in food service for packaging labels. Some restaurant POS systems also support caller ID integration, which pulls up a customer’s order history when a phone order comes in.

Before purchasing any accessory, verify compatibility with your POS platform. Not every add-on works with every system, and using unsupported hardware can create reliability issues that are difficult to troubleshoot. Your POS provider’s website will typically list approved or recommended accessories.

Buying, leasing and bundling POS hardware

There are three main approaches to acquiring POS hardware, and each has distinct trade-offs.

1. Buying outright requires the highest upfront investment but gives you full ownership of the equipment with no ongoing hardware payments. You’re free to use the hardware as long as it works and you’re not locked into a contract. For most small businesses, buying is the most cost-effective option over the life of the equipment.
2. Leasing lowers the upfront cost by spreading payments over a contract term, but the total cost over the life of the lease is almost always higher than the cost of purchasing outright. Leases may also lock you into a long-term agreement with the POS provider, making it expensive to switch if you’re unhappy. You’ll need to read the lease terms carefully; pay attention to the total cost of the lease, what happens at the end of the term (do you own the hardware or have to return it?), and whether there are early termination fees.
3. Bundled packages from POS providers combine a terminal, card reader and key peripherals at a discounted price compared to buying each component separately. Bundles are convenient and ensure compatibility, but they limit your ability to mix and match components from different manufacturers. For most small businesses, provider bundles are a good middle ground: You get a compatible kit at a reasonable price and avoid the research required to assemble a custom hardware stack.

Be careful with refurbished hardware. Buying refurbished tablets and standard peripherals (printers, scanners, cash drawers) can save money without significant risk. However, refurbished proprietary terminals may not be transferable between merchant accounts or be eligible for warranty support from the POS provider.

How to choose the right POS hardware for your business

The right POS hardware configuration depends more on your business type and daily workflow than on any feature comparison chart. Start by considering how transactions actually happen in your business, and let that drive your hardware decisions. 

The chart below identifies the hardware to prioritize based on business type and the key factors to consider when deciding between solutions.

Regardless of business type, balance your upfront budget against long-term cost and durability. The cheapest hardware may need replacing sooner, while overbuying features you won’t use wastes money. Focus on compatibility with your chosen POS software, build quality appropriate for your environment and the total cost of ownership over the expected life of the equipment.

A custom POS setup

POS hardware is modular by design, and you don’t need to buy everything at once. Start with the essentials for your operation — a terminal or tablet, a card reader, and one or two key peripherals — and expand as your business needs become clearer through daily use. Many businesses find that their initial assumptions about what they need change after a few weeks of live operations.

Prioritize three things above all: compatibility with your chosen POS software, durability for your specific environment and total cost of ownership rather than sticker price. A well-chosen hardware setup that fits your business’s workflow will serve you reliably for years. A poorly matched setup will create daily friction that adds up to real lost productivity and revenue over time.
