Payment Processing · Buyer guide
A phone-paired card reader is the cheapest way into card acceptance in the US, and on price alone the choice looks trivial. The readers this site's reviewed providers sell run from $29 to $199, and most sit around $50 to $80. The reader, though, is the smallest number in the decision. Each one pairs with its own provider's app and account, so buying it means accepting that provider's in-person rate, its monthly plan if the rate depends on one, and in one case a three-year contract. At a few thousand dollars a month in card sales, the gap between the cheapest and dearest rate is worth more each year than most of the readers cost.
Here is what each provider charges for the reader and for the sales you take on it, read from each one's own US pages on 20 October 2026. Prices exclude sales tax and shipping.
Take a market stall or mobile service taking $3,000 a month in cards: 100 sales averaging $30, all tapped or dipped, on US cards. On each provider's published rate, a month's processing comes to:
Helcim cannot be put on this basis without knowing the cards: its $20 of margin on that volume (0.40% plus 8 cents a sale) sits on top of interchange, which varies by card type. Helcim's own pricing page says its merchants' effective rate lands near or below 2%, but that is its claim, not a quote for your card mix.
Over a year the spread between GoDaddy's standard rate and Square's free plan is $216, and between PayPal and Square $184. Either is more than every reader on the list except Clover's and Helcim's. Add the reader to the first year and PayPal ($29 plus $932.40) and GoDaddy ($79 plus $900) come out about $200 ahead of Square ($59 plus $1,116). The cheapest reader is not what makes them cheaper; the rate is.
Two things change that ranking. The first is the subscription. A paid plan that cuts the rate is only worth it above a certain volume: Clover Essentials saves 0.1 points for $29.95 a month, which pays for itself at about $30,000 a month in card sales, and GoDaddy's Point of Sale Plus saves 0.2 points for $28.99, which breaks even at about $14,500. Most phone-reader businesses are well below both. The site's analysis of retail POS plan card rates runs the same arithmetic for Square, whose Plus plan breaks even at $49,000 a month. The second is the fixed fee. At a $10 average ticket, Square's 15 cents adds 1.5 points to every sale and GoDaddy's zero cents adds nothing, so a coffee cart and a contractor taking $500 invoices can rank the same providers in opposite orders.
Clover's website advertises a free Clover Go, through 31 December 2026. The terms on the same page set three conditions: at least $100,000 a year in card volume, a three-year merchant processing agreement, and activating the account within 30 days of approval. The offer is open only to businesses that have not had a merchant account with First Data Merchant Services, Clover's owner Fiserv's acquiring business, during 2026, and the terms say hardware rentals offered alongside it are subject to early termination fees.
A $199 reader is a poor trade for a three-year processing commitment. Every other reader on the list is bought outright with no contract, and the reader is the only thing you lose by leaving. If you are offered Clover Go free, ask for the processing agreement and its termination clause before accepting; the site's guide to processor contracts and early termination explains what to look for.
Generally not. A phone-paired reader encrypts card data for its own provider and is tied to that provider's processing, even where another company's app can drive it; PayPal, for one, says its reader works with other POS software. Shopify says its reader works only with Shopify Payments, and Helcim's needs an approved Helcim merchant account. None of the other providers says its reader works with anyone else's processing, and the site's guide to which card machines you can keep when you switch explains why. Treat the reader as a $29 to $199 sunk cost, which is exactly why the rate deserves the attention.
Apple's US list of Tap to Pay on iPhone providers includes Square, Stripe, Clover, GoDaddy, Helcim, PayPal and Venmo for Business, and Shopify's help centre confirms it offers Tap to Pay on iPhone in the US as well. Tapping a card on the phone costs the same as the reader at Square, Shopify and GoDaddy, and 10 cents more per sale at Stripe and Helcim; the site's Tap to Pay fee comparison sets them side by side. The catch is that a phone accepts only contactless cards and wallets. A customer whose card has no tap symbol needs a chip reader, which is the real reason to buy one.
