Understanding the key differences between mobile and fixed POS systems
Fixed POS systems rely on countertop payment terminals installed at checkout stations, typically paired with barcode scanners, receipt printers and cash drawers. They are ideal for high-volume, permanent locations and accounted for 54.9 percent of the UK market in 2024 due to their strong data security and reliability1.
In contrast, a mobile POS system uses portable terminals like tablets or smartphones, enabling staff to process transactions anywhere, in-store or remotely. With a projected 93 percent market growth by 2027 in the UK, mobile POS is gaining popularity for its flexibility, lower costs and improved customer experience2.
The choice between a portable terminal and a fixed terminal depends on operational flow, mobility requirements and the expected volume of transactions.
Advantages of mobile POS solutions for modern businesses
The mobile POS model offers significant benefits to businesses needing:
- Mobility and flexibility: Process transactions anywhere to improve the customer journey and shorten queues
- Lower setup costs: Mobile systems can work on existing hardware, reducing the need for expensive, dedicated devices
- Real-time analytics: Monitor sales, inventory and customer trends instantly for smarter decision-making
- Space efficiency: Reduces reliance on large checkout areas, maximising product display space and enhancing store layout
- Easy integration: Integrates with tools like inventory software, loyalty programmes and accounting apps
The use of a portable terminal also supports temporary locations like pop-up stores and outdoor markets. These benefits make the mobile POS especially attractive for retailers prioritising mobility, personalisation and lower upfront investment.
When fixed POS systems deliver superior results
While the mobile POS has become increasingly popular, fixed POS setups still hold strong advantages in certain conditions, such as:
- High transaction throughput: Ideal for supermarkets or chain stores managing a continuous flow of transactions
- Advanced features: Typically includes built-in capabilities for inventory tracking, employee management and robust reporting
- Durability and reliability: Hardware is designed for intensive daily use, with fewer concerns about device battery life or network stability
- Enhanced security: These systems are often physically secure and feature tighter data control
Countertop payment terminals associated with fixed systems are generally reliable. Their comprehensive features make them ideal for high-volume, brick-and-mortar businesses.
Making the right choice based on a business model
Retailers, hospitality venues and service providers must assess how mobility, hardware investment and checkout structure align with their objectives. When choosing between a mobile POS and a fixed POS, it’s important to consider:
- Business type and scale: Small cafes or event-based vendors benefit from portable terminals, while department stores may prefer countertop payment terminals
- Budget considerations: Mobile systems typically offer lower upfront costs, making them attractive for small and medium-sized businesses (SMBs) and growing retailers
- Operational complexity: Both systems deliver real-time analytics, customer data and integrated reporting
- Customer experience goals: Some sales models value bringing checkout to the customer, while others prefer to retain a centralised payment hub
