There are many different types of POS devices, including smartphones, tablets, mobile POS, card and chip readers, touch screens, computers, self-service kiosks, and terminals.

POS Apps

POS apps are cloud-based programs that you can download onto any compatible mobile device; you can access your POS information from any of these compatible devices. Some apps are available on multiple platforms, while others are specific to Android or iOS. There are also iPad-only POS apps.
They typically have slimmed-down features from a full-blown POS terminal, and additional features often come with extra fees. POS apps are still the most affordable type of POS overall—and they’re also typically the easiest to use.
| PROS | CONS |
|---|---|
| Flexible for making sales on the go, at events, or on the sales floor | More limited features than a full-blown POS system |
| Significantly lower cost than a full POS system | Cybersecurity can be a concern |
| Easy to stay up-to-date with technology and software updates | Hardware is generally a phone or tablet—not as durable as dedicated POS hardware |
Since POS apps are generally a smaller investment than a full system, they’re a great fit for new or small businesses with smaller budgets. They’re also ideal for those that frequent event sales or lack a permanent location. Some POS apps include features like calendar and appointment-setting for professional service providers like tradespeople who work on the go.
Typically, POS apps are best for:
- New businesses
- Small-scale service providers
- Mobile sellers
You can find POS apps with basic features for free, or paid versions ranging from about $30–$150 per month.
Popular POS apps include:

Mobile POS Systems

A mobile POS (or mPOS) system is best for retail merchants or restaurants that need a more full-featured system than an app but still want the flexibility to process transactions from anywhere. Vendors like food trucks, service providers, or traveling retailers, for example, are best suited for an mPOS system. These platforms are also a great solution for merchants who need to process both online and in-person transactions.
| PROS | CONS |
|---|---|
| Access business data from anywhere with cloud-based storage | Requires more investment than a standard POS |
| Easier to integrate new hardware than with a traditional POS | Some mobile POS systems only work with the iOS operating system |
| Process payments either on the go or at a brick-and-mortar shop | Devices are at a greater risk of being lost or stolen than a traditional POS |
Mobile POS systems are cloud-based and helpful for retailers and restaurants that want to boost associate presence on the floor and make the checkout experience more convenient for customers. In restaurants, for example, an mPOS might allow for tableside ordering or even payment. In retail, this can help you drive more sales so that customers don’t have to wait in line or seek out a register. Like POS apps, an mPOS can also come in handy for food trucks and event sales (such as markets, festivals, and similar off-site temporary retail opportunities).
mPOS systems are similar to POS apps in that they provide flexibility in terms of mobility. The difference here is that an mPOS encompasses both the hardware and software, whereas POS apps refer to just the software.
mPOS systems can boost in-store sales, especially as consumers grow increasingly comfortable with the payment option. The average mobile transaction value in the US is expected to increase from a little over $7,960.50 in 2021 to $11,755 in 2025.
An mPOS also doesn’t specifically limit the software to an app. While most mPOS systems use apps and hardware like iPads and the iOS operating system, some mPOS providers, such as Clover and Square, offer proprietary hardware.
Typically, mobile POS systems are best for:
- Food trucks
- Retailers needing to sell on the go, or on the sales floor
- High-volume restaurants wanting to speed up service by giving servers handheld systems
- Markets and temporary vendors
You can find a few mPOS systems with no software fees, but most cost around $60 per month. Popular mobile POS systems include:

A touch-screen POS system works on different types of touch screens, including tablets, smartphones, and computers. Some touch-screen POS systems come with their own native touch-screen hardware in lieu of a third-party device.
A touch-screen POS allows restaurant employees to take tableside orders and ensure orders are correct. The intuitive design of touch-screen software makes it easy for both customers and employees to use.
| PROS | CONS |
|---|---|
| Streamlined interface to make transactions quicker | Touch screens are more expensive than other types of POS systems |
| Intuitive design makes learning the system easier | Touch-screen system subscription plans can be expensive |
| More customizable than traditional POS systems | Not all touch-screen POS systems are both Android- and iOS-compatible |
A touch-screen POS is a great option for small businesses in the food industry, both in the context of allowing customers to place their own orders and having associates take their orders with the device. Touch screens are typically easy to use and intuitive, especially when you’re dealing with a younger demographic that is used to using tablets and smartphones.
Typically, touch-screen POS systems are best for:
- Fast-paced businesses like restaurants and high-volume retail stores
- Any business needing a system that’s easy to train employees on
While touch-screen POS hardware can range from a few hundred to a few thousand dollars, the software for each terminal is typically $50-$200 per month.

Cloud-based software records transactions in real time, so you can access your data quickly from anywhere with an internet connection. This is great for multilocation businesses, like restaurants, hotels, and retailers.
Small businesses with multiple POS systems or even locations benefit from a cloud POS, as data will sync to a centralized database (like temporary retail, so you can send that information back to your data HQ), giving you a holistic view of your business. Many cloud-based POS systems also include real-time inventory updates, which is helpful for retail merchants with multiple stores to track product levels.
| PROS | CONS |

| Access it from any compatible device, anywhere, anytime | Subscription fees can be costly |

Most modern POS systems are cloud-based, though there are some legacy or free open source POS systems that are locally stored or license-based, so the systems and data are only accessible from the single device or local network.
Typically, cloud POS systems are best for:
- Businesses wanting to access inventory, sales, or reporting data from anywhere
- Businesses wanting to save on hardware costs

Open Source POS Systems

While at first glance it may seem cost-effective, an open source POS requires resources to run that can add up. It also requires more maintenance and updates over time. This is why open source POS systems are ideal for larger enterprises or extremely tech-savvy small businesses.
Larger enterprises typically have more custom and unique needs, along with bigger budgets. For small businesses with technical and coding skills, open source POS systems can be an attractive option because they are often a free or low-cost investment.

You might also hear the term “open API” when discussing open source POS systems. You can find some open source POS systems for free, while others come with costs typically lower than other types of POS.
Typically, open source POS systems are best for:
- Businesses needing a highly customized solution
- Enterprises or big businesses with a large tech budget and/or development staff
Examples of open source POS systems include:

Multichannel POS Systems

Retailers who make both online and in-person sales need a solution to integrate and manage business data from one place. Multichannel POS systems are helpful for those that have both an online store and some sort of in-person selling component, be it temporary retail, event selling, or a brick-and-mortar store.
They help product-based businesses avoid stockouts by syncing inventory levels across channels. This is especially important for maintaining accurate business data, especially as the lines between online and offline commerce continue to intertwine.
| PROS | CONS |
|---|---|
| Access and manage data from all your sales channels in one place | Pricing models can be confusing, as prices sometimes differ between online and in-person sales |
| Offers convenience for customers by expanding purchasing options | Managing multichannel sales successfully can be challenging for new or small businesses |

Self-Service Kiosk POS Systems

Casual restaurants and cafes with simple menu options are a good fit for self-service kiosk POS systems because they reduce lines and wait times. In the retail environment, they have popped up in the self-checkout you typically see in grocery stores. With this, shoppers can place direct orders, scan their own items, and pay for their entire order themselves—shortening the checkout period and giving customers more control over their experience. This is especially helpful for minimizing person-to-person contact.
| PROS | CONS |
|---|---|
| Puts customer in control of making sure their order is correct and aligned with their preferences | Customization options for ordering can be limited |
| Reduces ordering wait times | Investing in the hardware can be expensive |
Self-service kiosk POS systems are made so customers can place orders and pay for products and services themselves without the help of an employee. You typically see these as digital touch screens at restaurants and cafes, particularly fast food and fast casual businesses. Self-service kiosks help shorten lines and waiting time. Some even allow customers to process their own payments.
Typically, self-service kiosk POS systems are best for:
- Quick service restaurants
- Markets, grocers, and cafes selling made-to-order and ready-to-eat items
- Hotels wanting to accept room charges as payment
