9 Best Mobile POS Systems of 2026

Square gives mobile sellers the widest choice of ways to take a card without changing software. A market trader can start with Tap to Pay on an iPhone or Android phone and no hardware at all, add the $59 Square Reader for contactless and chip when customers want to dip a card, and later move staff onto the $399 Square Handheld, which weighs 0.7 pounds and has a barcode scanner, dip slot and camera built in. All three run the same free Square Point of Sale app and share one item library, so stock and sales stay in one place. The reader keeps taking payments offline for up to 24 hours when there is no signal, which matters at outdoor events. The tradeoff is price per sale: Square Free charges 2.6% + 15¢ for in-person payments, and the lower rates on Square Plus cost $49 per location each month.

PayPal Point of Sale, the US version of what used to be Zettle, is the cheapest way on this list to start taking cards in person. There are no monthly or setup fees, the first Card Reader costs $29 and additional readers are $79, and a card-present payment costs 2.29% + $0.09. That rate also applies to QR code payments, which helps when a customer would rather pay with PayPal. The free app runs on phones and tablets and covers checkout, inventory and sales reports, and sales land in your PayPal balance within minutes. For sellers who want a dedicated device, the all-in-one Terminal costs $199, or $239 with a barcode scanner. The app is lighter than Square on staff permissions, loyalty and restaurant tools, and PayPal notes that transactions are subject to review and may be held or delayed, which is worth weighing if cash flow is tight.

SumUp is built for the seller who works alone and wants the lowest fixed cost. The free tier asks only for a one-time hardware purchase, with no monthly fee, no minimums and no rental, and every card-present payment costs 2.6% + 10¢, which is 5¢ less per sale than Square Free. The same account handles Tap to Pay, invoices and payment links, so a stall holder or delivery driver can take a remote payment as easily as a tap at the table. Payouts arrive the next day on all products. The limits show once a second person starts selling: syncing several devices, adding ticket printers and setting up floor plans requires POS Plus at $49 a month, and loyalty and multi-store tools sit in SumUp POS from $99 a month. Keyed card numbers and online payments cost 3.5% + 15¢, so it is best for sellers who mostly take cards in person.

Helcim suits mobile businesses that take enough card payments for flat rates to hurt. Instead of a fixed percentage, it passes through what the card networks charge plus a published margin, and it charges no monthly, software, statement or cancellation fees. For taking payments on the move, the Helcim Card Reader costs $199, has an all-day battery and pairs with phones, tablets and computers, and Tap to Pay on iPhone needs no hardware for an extra 10¢ per transaction. Field teams that work beyond Wi-Fi can switch on 4G mobile data for $7 a month, and the $349 Smart Terminal adds a printer and built-in POS. The software covers invoicing, inventory tracking, customer records and surcharging, and syncs sales across the POS and invoices in real time. It is less suited to restaurants, and the reader costs more upfront than the cheapest options here.

Shopify POS is the natural mobile checkout for brands that already run their online store on Shopify. Products, stock levels, customers and gift cards are shared between the website and the POS app, so a sale at a weekend market updates the same inventory the online store uses. For selling on the go, Tap to Pay on iPhone and Android turns a phone into a contactless checkout with no reader, and the POS Terminal gives floor staff a dedicated device for busting lines and checking stock. A countertop setup adds POS Hub, a scanner and a receipt printer when a pop-up becomes a shop. The catch is that Shopify POS is not a standalone free app: you need a Shopify plan, and richer staff permissions and inventory tools sit in POS Pro, which is charged per location. We could not confirm US dollar prices from this machine, so check the pricing page before you buy.

Clover Go pairs a small Bluetooth reader with the Clover Go app on an iPhone or Android device running iOS 15 or Android 9.0 and up. It accepts chip, swipe and contactless cards plus Apple Pay, Google Pay and Samsung Pay, and the app can also take Tap to Pay on iPhone, so a crew can still get paid if the reader is left in the van. Clover rates the battery at about 160 dips or 130 contactless payments per charge, and payments taken offline are authorized once the device reconnects. The app stores digital receipts, sends them by email or text and tracks open balances, and a Go Dock turns the reader into a countertop setup. Software comes in Starter and Essentials plans, with Essentials adding detailed reports and customer tools. Watch the terms: Clover devices only work with Clover processing and some subscriptions are non-cancelable, and its prices did not load as plain text for us, so they are pending.

Toast Go 3 is the strongest handheld on this list for hospitality, though it is not a general-purpose mobile POS. It has a 6.52 inch screen, weighs 0.94 pounds, carries an IP65 rating against dust and liquids and is rated for 5 foot drops, and Toast quotes a battery life of more than 24 hours. Payments are built in, with tap, dip, swipe and NFC, and PIN on glass. The cellular models matter most for selling on the go: they keep taking orders and cards on rooftops, patios, curbside and at off-site festivals, and queue orders when the device moves between Wi-Fi and cellular. Orders go straight to the kitchen, and cloud printing sends tickets across separate networks. The limits are clear: it runs only on Toast, new customers go through a demo to buy, and Toast software starts at $0 a month with the Starter Kit or $69 a month on the Point of Sale plan.

Heartland sells Genius, the Global Payments point of sale, to restaurants, retailers and service businesses, and its pocket-sized handheld lets staff take orders and payments anywhere in the store or dining room. Pricing is tiered and published: Essentials starts at $0 a month, Advanced at $42 and Complete at $129, each with 2.6% + $0.10 per in-person card transaction, though the fine print says final pricing depends on equipment, volume, business type and underwriting. The software adds loyalty programs, online and in-store branding, and the same system runs countertop stations and self-ordering. It is a sales-led product, so you get a quote rather than buying a reader online, and it is a poor fit for a solo seller at a weekend market. Heartland is also moving to the Global Payments brand, so some product pages have changed or moved.

Lightspeed Retail is the pick here for stores that need mobile checkout inside a shop rather than at a market stall. The POS installs on an iPad, so staff can walk the sales floor, look up stock and take payment with integrated processing, which cuts queues and lets you add register capacity on busy days. Inventory is the core strength: it follows every SKU, handles transfers between locations and returns to vendors, and supports wireless cash drawers, barcode scanners and receipt printers. Owners can watch sales and staff remotely through mobile reporting. The cost is the highest entry price on this list, with Basic at 89 USD a month, Core at 149 USD and Plus at 289 USD, and annual billing saving up to 18%. It is also tablet based, so it is not the right tool for a solo seller who wants to tap cards on a phone. A 14-day trial includes every feature.
