The History of Point of Sale (POS) Systems

Point of sale (POS) systems have undergone a remarkable transformation.

Evolving from simple cash registers to sophisticated digital platforms, computerised POS systems are now an essential part of any retail business operation.

Investigating the history of point-of-sale systems provides insights into how commerce has evolved and how technology continues to shape hospitality and retail operations.

The cash register's origins trace back to 1879 with the inventory and saloon owner, James Ritty. In one of his saloons in Dayton, Ohio, Ritty was frustrated by employee theft and wanted to find a better way to manage customer payments via cash.

At the time, transactions were recorded by hand in ledgers, which was a method that was both slow and error-prone. This is because the traditional cash register could only add up prices, calculate total payments and store cash.

While travelling on a steamboat trip the previous year, Ritty was fascinated by an apparatus that counted how many times the ship's propeller went around. Inspired by these mechanics, Ritty imagined a mechanical device that could automatically track cash sales in the same way.

Five years later, he collaborated with his brother, John, a skilled mechanic, to create this invention. Constructed from brass, wires, and gears, the first POS system was created and named “Ritty’s Incorruptible Cashier”.

His invention also featured the well-recognised bell sound upon completing a sale. The bartender would press a button, allowing the register to log the transaction and establish a record to deter theft.

In 1880, Ritty founded the Ritty Manufacturing Company to market his cash registers. However, Ritty became overwhelmed with the responsibilities of running two businesses, and the company failed to prosper, pushing Ritty to sell all his interests in the National Cash Register Company and the business.

It was John H. Patterson who truly revolutionised the cash register industry. In 1884, he acquired Ritty’s invention and founded the National Cash Register (NCR) Company, which refined and popularised the use of POS stations by adding a paper roll to record sales transactions.

In 1906, the NCR patented the innovation of the 'adding' mechanism, which kept a running total of all transactions throughout the day.

This was carried out with the help of Charles F. Kettering, who designed an electric motor and developed the first electric cash register.

By 1911, the NCR sold 1 million machines and had over 6,000 employees, with 95% of all cash registers sold in 1912.

Cash registers continued to evolve, incorporating brand-new features that improved the functionality of the operating system. In the early 1900s, cash registers started to feature cash drawers, improving the security of money storage.

By the 1920s, cash registers incorporated electric motors, allowing for faster and more efficient transactions. NCR registers also added keysets to allow merchants to track sales, and customer-facing displays were used to show itemised transactions.

Many core functions of modern POS systems can be traced back to NCR's early inventions. Their patents propelled NCR cash registers into widespread adoption in retail and department stores.

Later innovations brought forth cash registers equipped with barcode scanners, touch screens, and sophisticated computerised systems featuring inventory management software - all paving the way for the development of electronic cash registers.

The 1970s saw the emergence of the first electronic cash registers (ECR), with IBM (International Business Machines Corporation) taking the lead. In the 1970s, IBM released some store systems that were mainframe computers used in POS systems.

These innovations enabled businesses to electronically store transaction data through cloud computing and enhance record-keeping and report capabilities.

By 1974, the introduction of the first computerised credit card system allowed transactions to be completed in under a minute. This led to McDonald's rolling out their own POS terminals in 1984, integrating their fast-food order system with cashiering.

Additionally, throughout the 1980s, POS systems began utilising microprocessors for increased efficiency and functionality.

A significant breakthrough during this period was the emergence of barcode scanning, which transformed the retail sector by simplifying the checkout process.

Electronic cash registers also offered businesses essential sales analytics, allowing them to monitor trends, identify best-selling items and refine pricing strategies.

These advancements laid the groundwork for more advanced POS systems and facilitated the digital evolution of retail.

The 1990s were a pivotal era for point-of-sale (POS) technology, highlighted by the emergence of PC-based systems. The 90s also saw the introduction of electronic point of sale (EPOS) systems.

EPOS software enabled businesses to consolidate various functions - like sales tracking, customer data management, and stock counting - into one cohesive platform.

A pivotal moment took place in 1992 when Microsoft launched a Windows-based POS software, which significantly improved user experience as well as accessibility for businesses of all sizes.

During this period, the use of credit card payments expanded, alongside more advanced transaction recording capabilities.

These advancements set the stage for today’s cloud-based POS systems, which provide superior inventory management, streamlined customer data processing, and integration with customer relationship management (CRM) tools.

The early 2000s marked a significant transformation in point-of-sale (POS) technology, driven by the emergence of the internet and cloud-based systems.

Cloud-based POS systems allow retailers to access and manage their businesses with an internet connection, meaning that businesses can now access real-time sales data from anywhere, significantly decreasing their dependence on costly hardware.

The introduction of software-as-a-service (SaaS) models also made POS solutions more affordable by reducing both initial and ongoing expenses. During this period, integrating eCommerce became crucial, allowing companies to seamlessly manage online and in-store sales through a unified piece of sales software.

Additionally, by the 2000s, modern POS systems also began to offer inventory management, such as vendor ordering and customer relationship management features.

The shift to cloud-based systems empowered retailers to track sales and employee performance remotely while also providing real-time business data on customer behaviour for improved decision-making.

The trend of mobile POS has also coincided with the rise of cloud-based POS systems, which enabled their transactions to take place on mobile devices.

The rise of mobile POS systems not only facilitates transactions via smartphones and tablets but also further enhances flexibility and convenience for both businesses and their customers.

The 2010s marked the beginning of a mobile revolution that fundamentally changed how businesses handled payments.

With the advent of smartphones and tablets, small businesses gained the ability to process credit card payments through mobile devices which enhances the accessibility and flexibility of transactions.

This era also witnessed the emergence of contactless payment methods, driven by NFC (Near Field Communication) technology, which facilitated faster and more secure transactions through platforms like Apple Pay, Google Pay, and tap-to-pay credit cards.

To cater to the needs of both online and in-store shoppers, businesses implemented omnichannel POS solutions that integrated sales seamlessly across different platforms.

For example, as advancements in AI and machine learning progressed, POS systems began to incorporate features like predictive analytics, tailored customer interactions and fraud detection capabilities.

Retailers also started utilising self-checkout kiosks, AI-driven chatbots, and voice-activated POS terminals, which not only cut down on labour costs but also improved operational efficiency.

With the integration of cloud technology, retailers can monitor sales and track employee performance using modern POS systems.

Furthermore, AI-enhanced real-time inventory management is a key feature of cloud-based POS systems because it optimises operations and prevents stock issues.

Despite the many advantages and beneficial aspects of POS systems, security remains a crucial concern because of the vulnerability to both internal and external threats.

Employees can exploit POS systems to commit theft, which is why businesses need to implement preventative measures such as security cameras and alarms to deter fraud.

Additionally, POS systems can also be susceptible to hacking and data breaches, with cybercriminals targeting them to steal credit card information.

Therefore, to protect sensitive information, password protection is essential to secure POS databases. Businesses must not only enforce strong password protection but also manually update software regularly and implement good cybersecurity measures.

In the end, by prioritising security, businesses can reduce the risk of theft and fraud, ensuring a safer transaction environment for both customers and employees.

Blockchain-based transactions will provide more secure and transparent payments, reducing fraud and ensuring data integrity.

In addition, Augmented Reality (AR) will transform shopping by allowing customers to see products in a virtual space before they buy.

Advanced biometric methods, including facial recognition and fingerprint scanning, will make checkouts quicker and more secure, further reducing the risk of fraud.

Moreover, AI-driven hyper-personalisation will empower businesses to deliver customised promotions and instant recommendations, overall enriching the shopping journey and boosting customer loyalty.

The POS evolution, from James Ritty’s original mechanical cash register to today’s sophisticated AI platforms, underscores the relentless advancement of technology in business.

As innovations continue to surface, the POS sector is on track to revolutionise convenience, security, and efficiency, ultimately reshaping the landscape of retail and hospitality.
