Components of a Point of Sale (POS) System

Point of sale (POS) systems comprise two components – hardware and software.

Hardware Components

  • 1.POS Terminal: The point of sale (POS) terminal (usually a desktop, iPad, or tablet) is the device on which the point of sale (POS) software is installed. Earlier, checkout processes used to take place at a specific checkout counter but with the introduction of mobile point of sale (mPOS) systems, payment processing and checkouts take place from any location within the store. A stable internet connection and a sturdy device.
  • 2.Barcode Scanner: These are the most essential hardware components of a point of sale (POS) system. As the name implies, these devices are used to scan barcodes from commodities and extract and display information related to them on the monitor. This not only speeds the transaction processes but also helps in checking inventory levels, availability of products, etc.
  • 3.Payment Processor: Since cashless transactions are trending and extremely convenient, it is advisable to own a payment processor that is capable of supporting any mode of payment. This ensures contactless payments in a physical store and is convenient for customers too.
  • 4.Cash Drawer: With digitisation on the rise, people mostly prefer contactless and cashless payments. But, there still are people who prefer cash payments. To store the cash and other receipts and bills safely, you require a secure place. This is where you need a cash drawer (either fliptop cash drawers or USB cash drawers).
  • 5.Receipt Printer: These devices are used to print payment receipts for the customers and contain purchase-related information like date and time of purchase, place of purchase, product name, SKU number, price of the product, etc., for example, Epson TM-M30II Thermal Receipt Printer. There are two primary types of receipt printers- dot matrix receipt printers and thermal receipt printers.

Some of the other hardware components used by many businesses include-

  • 1.Customer-facing Display: These monitors/displays are usually placed on the checkout counters and are used to display the amount the customer owes for the chosen product/service and the cost breakup. These devices are preferred by most businesses as they help in maintaining transparency with the customers, thereby providing better customer service.
  • 2.Self-service Kiosks: These are self-order point of sale (POS) systems using which customers can place the order and pay for it on their own. This enables contactless customer service and customers can quickly and conveniently purchase the required products without having to wait in queues at checkout counters. Self-service kiosks help boost business operations efficiently.
  • 3.Scale: If you own a grocery store, a warehouse, or a laboratory, you would require weighing scales. There are three types of weighing scales- strain gage load cells, force motor scales, and ultra-precision scales.

Software Components

Referred to as the ‘backend’ of a point of sale (POS) system, the software components are used specifically for backend management and analytics. Ideally, the point of sale (POS) software is the operating system that integrates the hardware components and ensures that they work in sync to ensure seamless business operations. The store employees use the front-end interface and the back-end is accessed through a browser or app. Premium quality point of sale (POS) software allows users to operate and manage the entire business operations from a central location. On-site and cloud-based are the two methods to store data. On-site data is installed on your local server and requires you to purchase software licenses to use them whereas cloud-based storage, also known as Software-as-a-Service (SaaS) is hosted online and allows you to access data from the browser from any location, at any time. Vend, Square POS, Shopify, and LightSpeed are some of the popular point of sale (POS) software.
