How to Choose a Credit Card Machine for Your Small Business | Costs

Match a card machine to your payment types, checkout setup, and total cost — hardware price alone decides nothing.

A $59 reader and an $899 register both accept the same tap, so sticker price says little about fit. Choosing a credit card machine for your small business comes down to three questions in order: what customers hand you, where the sale happens, and what the machine must connect to afterward. Get those sorted and the hardware list shrinks fast.

What Should A Card Machine Handle Before You Buy?

Every machine worth buying in the US today must accept EMV chip cards and NFC contactless payments, including Apple Pay and Google Pay. Keep magnetic-stripe swipes only if customers or a legacy workflow still depend on them.

• Payment types. Chip and contactless are the baseline. GoDaddy’s card reader documentation describes contactless and chip payments plus digital wallets, and Square’s readers cover tap, dip, and swipe.
• Operating model. A phone or tablet reader is the cheapest way to go portable. A standalone terminal earns its price at a fixed counter, when receipts need printing, or when you don’t want checkout on a personal phone. An all-in-one register makes sense when inventory, employee permissions, customer displays, and reporting sit at the center of how you sell.
• Compatibility. Confirm the exact iOS or Android version, supported phone or tablet model, and whether the connection is Bluetooth or USB. GoDaddy’s setup requires downloading the GoDaddy Commerce App and pairing over Bluetooth, and Square Stand needs a compatible iPad — if yours isn’t listed, the $59 reader plus a phone does the same job.
• Connectivity. Decide whether you need Wi-Fi, Bluetooth, cellular data, or offline mode, test signal strength at the exact payment spot, and line up a backup connection.

One more decision: who runs the checkout. If staff turn over often, pick a system with separate employee logins and permission levels, because shared passwords are how refund fraud starts.

Choosing A Credit Card Machine: What Decides The Outcome

Total cost, not hardware price, decides which machine is genuinely inexpensive. Compare options with one formula: hardware + monthly software + (monthly card volume × processing rate) + optional fees.

Processing rates move the total more than hardware once volume grows.

Also read contract terms: minimums, equipment leases, early-termination clauses, deposits, payout timing, chargeback fees, and whether the provider is also the processor holding your money. Add small line items — accessories, cellular service, receipt paper, paid integrations — because those turn a bargain machine into an expensive one.

Card data security is not optional. PCI DSS sets the baseline requirements for any business that stores, processes, or transmits cardholder data, and small merchants usually validate through a self-assessment questionnaire. The PCI Security Standards Council’s merchant resources cover device approval and point-to-point encryption. In practice: keep firmware and apps updated, limit who can sign in, and test chip, tap, wallet, refund, and receipt workflows before a customer is waiting.

Then compare real candidates side by side — the tested credit card machine roundup ranks current models by rate, hardware cost, and counter footprint.

Most US small businesses do best with a $59 contactless-and-chip reader paired with a phone they already own. Step up to a $299 standalone terminal when printed receipts at a fixed counter matter, and to an all-in-one register only when inventory, staff permissions, and a customer display earn their keep.
