As more customers are using plastic to pay for purchases, equipping your business with a credit card machine is crucial. Learn more about the types of credit card machines and how to choose the right one.
A credit card machine is hardware used to read credit cards and may also be referred to as a reader, payment terminal, POS system, or smart terminal.
Choosing the right credit card machine can be challenging for brick-and-mortar business owners who are forced to sift through the overwhelming number of payment terminals on the market.
Fortunately, this guide takes a deep dive into credit card machines, including the different types of payment terminals and how to choose the best one for your business.
What Are Credit Card Machines?
Credit card machines are the hardware that is used to accept payments from customers using debit or credit cards. Credit card machines are also referred to as payment terminals, credit card readers, or POS hardware.
Traditional credit card machines are recognizable from their PIN pads, card swiping or insert slots, or plastic pen used to collect signatures.
However, not all credit card machines have these features. The key feature of credit card machines is the ability to read and send card information during a transaction.
How Do Payment Terminals Work?
A payment terminal is the starting point of a debit or credit card transaction. Customers swipe, tap, or insert their card into the payment terminal’s hardware. In this interaction, the payment terminal collects the customer’s card information and sends that data to your payment processor or bank via the internet.
Your processor will send a request for payment to the customer’s card network, which will in turn check to see whether the customer has enough funds to cover the transaction. If the customer is good for the payment, they’ll be asked to sign or enter their Personal Identification Number (PIN) code to securely verify their acceptance of the transaction.
After this step, the transaction is completed from the customer’s perspective. However, merchants must wait for the completion of the submission and settlement transaction stages to receive their funds. The entire process takes several days, after which settled funds will appear in your business’s merchant account.
As long as you do the work of preventing chargebacks, you’ll likely see very few interruptions to your business’s cash flow.

There are several types of credit card machines available, including traditional payment terminals, wireless credit card machines, mobile swipers, card readers, smart terminals, virtual terminals, and integrated credit card machines. Let’s take a look at the different types of credit card machines for small businesses.
Traditional Credit Card Machines
A traditional credit card machine is one that’s connected to the internet via a physical, wired connection such as an ethernet or telephone line.
Traditional terminals come in all shapes and sizes. They can be small devices just five or six inches long, with or without a PIN pad and/or a signature pad. They can be connected to a cash register in various ways so that the payment amount can be displayed on the terminal.
Some terminals have a built-in receipt printer, and others do not. They can process the card as a stand-alone device, or they can be connected to a point of sale system (see below) for additional data collection for your business.
Smart Terminals
Smart terminals have more processing power than traditional terminals and more technologically advanced features — it’s similar to the difference between a traditional phone and a smartphone.
While a smart terminal can connect directly to a landline, they typically are wireless terminals with a built-in printer. Often they have a touchpad display, and the display can be used to capture a signature or show a PIN pad, depending on the situation. The smart terminal may also include additional hardware features such as a scanner.
Despite these integrated hardware features, a smart terminal can be a small, handheld device that can be taken off a store’s counter and into more mobile environments.
The software loaded onto a smart terminal typically is a point of sale software instead of basic card reader software.
Companies that offer smart terminals tend to be those with a newer business model (i.e. third-party processors) that sell their other business management services in addition to credit card processing services. Smart terminals include the Square Terminal, the Clover Flex, and the Poynt, all of which have a modern, clean look.
Wireless Credit Card Machines
Wireless credit card machines connect to the internet via Wi-Fi and are portable as long as they remain connected to the internet.
If you have a Wi-Fi reader at the checkout counter, the signal is transmitted from the reader to the wireless gateway/router at your store before it goes to a landline and onto the internet. If you’re using a cellular connection through your phone or tablet, the information is transmitted from the device to the cellular base station and then onto the internet via a landline network.
Even though these devices communicate through wireless signals, some of them are still plugged into an electrical socket to provide power. Others, however, use rechargeable batteries. Despite the need to charge the devices, the wireless terminals can offer a merchant a great deal of flexibility, since the readers can be moved around at will, either to different stations or off-premise (for example, use at a trade show).
The only thing to watch out for when using a wireless or portable reader is that you must have a strong signal, whether Wi-Fi or cellular, for them to work.
Mobile Swipers & Card Readers
Mobile swipers and card readers are bare-bones hardware with only one function: to read the information of a payment card, encrypt the information if necessary, and send the information a very short distance to another more complex piece of hardware that delivers the information to the processor.
These hardware devices are called credit card readers or mobile swipers. Mobile swipers are physically attached to a smartphone through a headphone jack or are connected to the device via Bluetooth. Card readers rely on mobile processing apps or mobile point of sale (mPOS) apps.
An mPOS app is typically the same or a simplified version of the more elaborate POS software sometimes loaded onto smart terminals or fully-integrated credit card machines. This very robust software not only allows you to take a payment, but it can also keep track of other things like employee hours or inventory and generate reports related to them.
Another feature of these apps is they allow you to enter credit card information directly into the app, without any other machine. Even if you don’t have the hardware, you can use a mobile processing app to take credit card sales.
Fortunately, there are many free credit card readers offered by POS software companies, so you won’t need to spend extra for the added flexibility that mPOS readers offer.
Debit Card Machines
Debit card machines are the same as credit card machines since you can accept debit cards with any type of credit card terminal. However, there is a difference between debit and credit card transactions.
While you can accept debit cards with any type of credit card terminal, there are two different ways to run a debit card charge: the credit method and the debit method. You pay a different fee, depending on the way you run the charge.
If you run a debit card using the credit method, you pay the same fee you would if you had run the card as a credit card.
The cost of debit card transactions is only lower than credit card transactions if you run the card using the debit method. In order to do that, you need a machine with a PIN pad because all true debit charges require a PIN to authorize the charge.
Integrated Credit Card Machines
Integrated credit card machines are the most complete systems for a merchant to use to accept payments. They come with hardware and software — typically point of sale software — already loaded into the machines.
They are full-fledged systems that come with all the bells and whistles, including a large display, cash drawer, receipt printer, PIN pad and/or extra customer-facing display, and handheld scanner.
The price of these systems can get quite expensive when compared to the other terminals discussed earlier. However, these systems come with fully functional POS software (which may require you to pay an additional monthly fee) that should help you simplify various aspects of running your business.
Virtual Terminals
Virtual terminals allow card information to be entered in-app or within web browsers. Although virtual terminals don’t require any specific hardware, they still fall under the payment terminal umbrella.
To use a virtual terminal, simply key in the credit card information into your computer’s browser or an app, and then the card is processed (note the process rate is typically higher because these are card-not-present transactions that have a higher rate of fraud). Virtual terminals are especially suited for online businesses or for businesses that take payments by phone (e.g., food delivery businesses). Some virtual terminals allow you to customize the page and then open it to your customers so they can enter the credit card information themselves to finalize a purchase.
Some virtual terminals allow you to pair a card reader that connects to your computer via USB, headphone jack, Wi-Fi, or Bluetooth. This way, you can take advantage of the lower rates of a card-present transaction. Because a virtual terminal is a software-only method to take a payment card charge, they are not considered credit card “machines.”
Credit Card Machines VS POS
Functionality is the primary difference between a credit card machine and POS, with credit card machines being limited to payment acceptance and POS systems have broader applications including cash acceptance, item scanning, timeclock hardware, and inventory management.
Additionally, a POS system will include credit card machines, while credit card machines are considered standalone products that don’t typically need POS software support.
How To Choose The Right Credit Card Machine Or Payment Terminal For Your Business
To choose the right credit card machine or terminal for your business, consider which payment processor would best suit your business, what features you’re looking for, cost, and POS software integration options.
Here’s a breakdown of which factors to consider when choosing the best credit card machine for your business.
Choosing The Right Payment Processor
It is essential to find a good processor and then look at hardware offerings instead of the other way around. Some of the really good processors will even let you buy or bring your old machines when you sign up with them. Then, for a small fee or sometimes for free, they can reprogram the machines to work with their backend software.
Depending on your particular situation, consider doing one of the following:
- If you already have a credit card machine/POS system, ask your hardware provider for a list of processors that use software compatible with your hardware. This way, you make sure that your existing hardware can be re-used.
- If you really want an integrated system, shop around. Many payment processors offer Clover, but the contract terms and pricing markups for the hardware can vary quite a bit. We also strongly recommend against leasing your payment processing hardware, which unfortunately is still a common practice, especially with Clover.
- If you don’t know or don’t care too much about the hardware, find a good payment processor with low credit card processing fees. They will talk you through your specific needs and make sensible suggestions from their available options.
Card Reader Capability
The card reader should be capable of reading EMV (i.e., chip) cards because EMV readers reduce your fraud liability. Fortunately, most card readers have that capability these days, and only a few readers are magnetic stripe readers only. NFC reading capability for electronic wallets such as Apple Pay or Google Pay is nice to have, but not as essential as EMV.
Cost Of Credit Card Machines & Your Budget
Figure out your budget for the machine and stick to it. Credit card machines run the gamut in prices, from completely free to $1,000+. The difference between the two is the same as the difference between driving a luxury car and a subcompact — they will both get you from point A to point B, but only one of them will give you a journey catered to your comfort and convenience.
For credit card machines, the difference often comes down to the type of software loaded into the machine — a machine loaded with modern POS software can provide a lot of convenience for a busy business owner.
With some third-party processors such as Square, not only do you get a free reader, you can use many aspects of their POS software for free. So, before you settle on a machine, be sure to consider your business’s hardware and software needs as a whole, both for now and several years from now.
Integration With POS Software
Elaborating a little more on the POS software, you might want to consider whether and how well you wish to integrate your card terminal with any POS software. Basically, this comes down to convenience and the type of business you run. Automatically syncing the card authorization with the payment submission after a transaction can save you a little bit of time (often just a matter of punching an extra button, but this can get tedious if you have a line of customers).
If your business takes just a few payment card charges every day or even every hour, then automatically syncing your sales with sales reports and inventory might not be important. But if you have a lot of customers every day, the syncing ability could save you a lot of time with the administrative work/daily bookkeeping for your business.
The Bottom Line On Credit Card Machines
Credit card machines are just hardware that take information from cards and forward it to your processor. They’re important, but within the same type of card machine, there isn’t a lot of variety in terms of security features and functionality.
In fact, there are more merchant services providers with more variance in pricing, contract terms, and quality of customer service than there are credit card machine manufacturers. If you look carefully, many of these providers offer the same hardware at different prices.
What’s most important is your credit card processor, which will ultimately allow your business to accept credit card payments and get paid. Fortunately, the best credit card payment processing companies offer extensive support for multiple credit card machine types, prices for every budget, and POS integration options.
If you’d like to take a credit card machine-first approach, the best credit card machines and terminals offer a range of hardware options, POS integration options, affordability, and multiple ways to accept payments for your business.
