Why Square Terminal Is The Best Choice For Low-Volume Retail Businesses

Square Terminal is a great choice for small businesses that need a reliable terminal to accept credit and debit card transactions at their brick-and-mortar location. It also adds several features you won't normally find at this price point, including a stripped-down version of the Square for Restaurants app. While there's no support for Bluetooth peripherals, you can use an optional USB hub to connect a variety of add-ons, including some third-party devices.

Square Terminal is one of the most affordable devices we've found that can function as a mobile or countertop terminal, although it's a little on the large size for mobile use. Square Terminal comes with the Square payments app pre-installed and can be purchased at full price or via installment payments.

If you're having trouble deciding between this device and the Square Register (see below), check out our guide on Square POS readers and bundles for a side-by-side comparison of every product that Square currently offers.

5.5″ color touchscreen
Built-in thermal receipt printer

Wi-Fi and Ethernet connectivity

square register with credit card

Why Square Register Is The Best Choice For Low-Cost Access To POS Features

Square Register combines the power of a fully-featured POS system with Square's affordable credit card processing service. At $799, this is one of the most affordable countertop POS systems you'll find anywhere. You will likely need to purchase some accessories, including a receipt printer and a cash drawer. However, Square offers Square Register bundles that can save money over buying each product individually.

Unlike most POS system providers, Square uses the same pay-as-you-go billing model, regardless of which hardware product you use. Square Terminal's built-in software list is impressive and includes support for inventory management, employee management, loyalty/gift card programs, appointment scheduling, reporting, and eCommerce sales. Special features for restaurants are also available.

Square Register Features

Although it only works with Square’s payment processing service, the Square Register is an excellent choice for businesses that need the power and extra functionality of a full point of sale (POS) system.

With Square Register, you’ll enjoy the following major features:

13.25″ register display
7″ customer-facing display
Wi-Fi and Ethernet connectivity
Accepts EMV and magstripe payments
Accepts NFC-based payment methods (Apple Pay, Google Pay, Samsung Pay, and Cash App Pay)
Supports USB peripherals via an integrated 5-port hub
Includes Square POS, Square for Retail, and Square for Restaurants (free version) apps
Expandable via Square App Marketplace

Square Register Hardware Cost & Options

$799/unit (or $39/month for 24 months)
$12 for an extended 6.5′ customer display cable
$299 for a USB receipt printer
$119 for a USB barcode scanner
$129 for a 16″ printer-driven cash drawer
Other accessories and replacement parts available on Square’s website

Square Register Payment Processing Costs

No monthly fees (for basic accounts)
2.6% + $0.10/in-person transaction (swiped, dipped, or tapped)
Custom pricing for businesses processing over $250,000/year
Additional monthly fees for optional services (Square for Restaurants’ paid version, etc.)

There are no additional fees or long-term contracts. However, be aware that Square’s flat-rate pricing might be more expensive than a full-service merchant account if your monthly processing volume is higher than $5,000.

Why Clover Mini Is The Best Choice For POS Features In A Small Form Factor

The Clover Mini offers nearly all of the point-of-sale capabilities of the larger Clover Station Solo/Duo but in a smaller (and less expensive) form factor. Like other Clover devices, you can expand the functionality of the Clover Mini by installing additional apps from the Clover App Market. Most of these are free, but some require additional monthly subscriptions.

The Clover Mini is a great choice for businesses that don't need the capabilities of a full-blown POS system but want something more than just a basic credit card terminal. It's not the most affordable option, however, costing nearly twice as much as similar products from competitors and requiring a monthly software subscription fee. Clover Mini is available directly from Clover or through one of several of the best Clover resellers.

Clover Mini Features

Clover’s terminals and POS systems are popular with merchants due to their ease of use and expandability via the Clover App Market. The Clover Mini combines the expandability of larger Clover POS systems with the form factor of a standard countertop terminal and includes the following key features:

8″ color touchscreen display
Uses 110V AC power
Wi-Fi, Ethernet, and LTE connectivity
Accepts EMV and magstripe payments
Accepts NFC-based payment methods (Apple Pay, Google Pay, PayPal/Venmo)
Supports cash, paper checks, and gift card payments
Includes integrated PIN pad for debit cards
Includes built-in thermal dot receipt printer
Optional cash drawer available
Includes virtual terminal for keyed-in transactions
Expandable via Clover App Marketplace
Can be used as a customer-facing display with Clover Station POS

Clover Mini Hardware Cost & Options

$799/unit
$69 for the cash drawer
$0-$84.95 monthly software subscription fee (depending on the plan chosen)

Clover Mini Payment Processing Costs

2.3%-2.6% + $0.10/in-person transaction (through Clover Payments)
3.5% + $0.10/keyed-in transaction (through Clover Payments)
Variable processing fees (through Fiserv or Fiserv ISO)

Clover Flex 2023

Why Clover Flex Is The Best Choice For A Full-Featured Mobile Terminal

If you like Clover's point-of-sale functionality but need a mobile device, the Clover Flex is a good choice. With eight hours of battery life, it's ideal for businesses that need to process transactions in the field. However, it can also function as a countertop terminal if preferred. For truly mobile use in the field, you'll need to purchase an optional cellular data plan.

The ability to install apps and the addition of a built-in printer make the Clover Flex a great choice for businesses that need to accept payments wherever their customers are, although it's rather bulky compared to most smartphones. While the device itself is reasonably priced, the need for a monthly software subscription fee (and possibly a cellular data plan) adds to your overall costs.

Clover Flex Features

The Clover Flex bridges the gap between mobile and traditional countertop terminals, functioning equally well in either environment. Like other Clover devices, it comes with a bevy of features and can be expanded even more with apps from the Clover App Marketplace.

Here are the primary specifications:

Nearly 6″ color touchscreen display
8+ hours of battery life
Wi-Fi and LTE connectivity
Accepts EMV and magstripe payments
Accepts NFC-based payment methods (Apple Pay, Google Pay, Samsung Pay)
Includes built-in thermal dot receipt printer
Includes virtual terminal for keyed-in transactions
Expandable via Clover App Marketplace

Clover Flex Hardware Cost & Options

$599/unit (or $35/month for 36 months)
$0-$49.95 monthly software subscription fee (depending on the plan chosen)
$15/month for LTE cellular data plan

Clover Flex Payment Processing Costs

2.3%-2.6% + $0.10/in-person transaction (through Clover Payments)

Helcim Smart Terminal POS

Why Helcim Smart Terminal Is The Best Choice For Low-Cost Smart Terminal Functionality

We chose the Helcim Smart Terminal as one of the most cost-effective smart terminals on the market. The Helcim Smart Terminal has everything you need to get up and running for just $329. The terminal can be plugged in for countertop use but will also run for up to eight hours of mobile use. Helcim's proprietary POS software is pre-installed and includes additional features such as inventory management and employee log-in functions. It requires a Wi-Fi connection but doesn't offer cellular connectivity for true in-the-field use.

Helcim itself is an outstanding credit card processor for small businesses. With no monthly fee and a transparent interchange-plus pricing schedule for all users, it can accommodate most small and mid-sized businesses. (Note that Helcim does not accept high-risk merchants.)

The Helcim Smart Terminal is a great choice for businesses looking for an all-in-one solution that doesn't require a lot of extra fees and optional features. Setup is easy, and you can be up and running very quickly once your Helcim account is approved and your Helcim Smart Terminal arrives.

7 Features To Look For In A Credit Card Processing Machine

Before you decide on a particular type of credit card terminal, consider all of the features listed below and how they’ll fit in with your business’s needs. Here are the things to look for in choosing a credit card machine:

Processor Compatibility

Above all else, you’ll need to ensure that your chosen credit card machine is compatible with your credit card processor. Many providers sell proprietary hardware that can only be used with their processing networks. However, universal options are also available that sync up with most processors and give you more flexibility.

Some credit card processors charge reprogramming fees (typically around $100) to configure your existing terminal to work with their network, while others perform this service at no cost to you.

Payment Method Support

EMV (or “chip”) cards have been the standard payment method in the United States since 2015, and you shouldn’t purchase any terminal that lacks this capability. Magstripe processing remains important, but only as a backup method of processing a customer’s card. Today, most new terminals also support NFC-based (or contactless) payment methods, such as Apple Pay and Google Pay.

Adoption by consumers of contactless payment methods has steadily grown over the last few years, but the COVID-19 pandemic really pushed it into overdrive. As long as your chosen credit card machine supports these three payment methods, you shouldn’t have to worry about replacing it for many years to come.

Support for payment via QR codes or gift cards can also be valuable for some businesses. Support for advanced security features, such as credit card tokenization and encryption, is also essential.

Connectivity Options

Your level of connectivity is also crucial, as any downtime or lag that impedes your ability to process payments can have a significantly negative impact on your business. Most newer machines can send transactions to your processor over the internet through either a Wi-Fi or hard-wired (Ethernet) connection. Many terminals can also connect via a landline telephone line if your internet connection is unavailable.

Wireless terminals designed to be used in the field instead of at a fixed retail location rely on a cellular data connection that’s the same as what your smartphone uses. Unfortunately, these data plans typically run an extra $15-30 per month on top of the cost of the machine. If you want to purchase one of these terminals, ensure that it operates on either the LTE or 5G network, as the older 3G network is no longer in service with most carriers.

PIN Debit Support

Since you’ll be accepting debit cards as well as credit cards with your terminal, it’s essential that you include a PIN pad (either built-in or as a separate, customer-facing unit) for customers to enter their PIN.

While you can run a debit card “as credit” (without a PIN), you’ll miss out on the significantly lower processing costs associated with PIN debit transactions. These lower rates are generally only available with interchange-plus or membership pricing plans. Flat-rate and tiered plans usually charge the same rates for both debit and credit cards.

EBT Payments Support

Depending on your industry, you may also need a device that handles EBT (Electronic Benefits Transfer) payments. This capability is most important for grocery and general merchandise stores. There are no processing fees for EBT transactions (except those tacked on by your merchant account provider), so it’s in your best interest to expand your customer base by supporting this payment method.

In the healthcare industry, support for HSA and FSA accounts — which also use debit cards tied to the user’s HSA/FSA account — is also a must.

Receipt Printer

Although sending customers their receipts via email is becoming more popular, most receipts are still printed on paper and handed to the customer at the point of sale. You’ll want a device that includes a reliable built-in printer, even if it’s a battery-operated wireless device.

Smart Terminal Functions

Smart terminals add significant capabilities to your humble credit card machine that were once reserved for much more expensive POS systems. But do you really need them? If the answer is “yes,” then go ahead and spend the extra money to add the additional capabilities of a smart terminal to your payment acceptance solution. Smart terminals are rapidly replacing the older, not-so-smart credit card terminals — especially in states that have mandated customer-facing displays.

Which Credit Card Machine Is Right For My Business?

The best credit card machine for small businesses will meet your needs today and support up-and-coming technology trends that will become more important in the future. These trends include NFC capability for contactless payments and the ability to connect to a payment gateway for tokenized in-person transactions.

At the same time, we strongly encourage you to avoid the temptation to choose a merchant services provider because it offers a certain terminal that you like. Fair contract terms, reasonable prices, and excellent customer service are more important considerations in the long run.

As we’ve seen, hardware capabilities don’t vary much from company to company. For example, we really love the Clover line of terminals and POS systems and the expanded capabilities they bring to a business. But we’ve also received many complaints from merchants who signed up with Fiserv (formerly First Data) or one of its less-than-stellar ISOs because they liked the Clover machines. Then they discover that they were locked into a long-term contract, charged exorbitant rates and fees, and offered poor customer service. Worst of all, they couldn’t take their Clover equipment to a new provider if they wanted to switch to a better provider.

FAQs: Credit Card Machines & Terminals

How does a credit card terminal work?

Credit card terminals collect payment data in a variety of ways. EMV and magstripe terminals read data encoded directly onto your customer’s card through a magnetic stripe or an embedded EMV chip. NFC-equipped terminals use near-field communication to transmit and receive data wirelessly between either the customer’s card (tap-to-pay) or mobile device (Apple Pay, Google Pay, etc.). The terminal sends this data to your provider’s payment processing network through a landline, cellphone, Ethernet, or Wi-Fi connection. Modern terminals increasingly communicate with your processor via a payment gateway for enhanced security and cloud-based data synchronization.

Do credit card machines need internet?

While traditional credit card machines communicated over landline telephone connections, most modern payment terminals send data over the internet (either wirelessly or through a wired connection). One feature to look for is “offline processing,” which allows a terminal to store payment data when its internet connection is disrupted and then transmit it automatically when the connection is restored.
