Software and Hardware Components of POS Systems
As we look at the components of POS systems, it’s first important to understand the software options available and what each requires.
Software Components
There are two common software deployment methods:
On-premise: A traditional software model. Purchase one or more licenses upfront for the software and install it on your computer system or servers. You’re in charge of updating and maintaining the software, which may require dedicated IT personnel for larger organizations.
Cloud-based: Also known as Software-as-a-Service (SaaS) POS solutions. You access and support the system via the internet. Don’t worry—if your internet goes down, most systems track sales and sync them once you’re back online.

Experts Say !
“Flexibility is key. Ensure your POS vendor works with the payment processor/gateway of your choice, so that you can control cost. If you’re already using applications important to your business, make sure the POS can integrate with them seamlessly, so that you can continue using them.”

Hardware Components

Regardless of your chosen software deployment method, the hardware is the same. Grullon says the following hardware components are crucial for supporting POS software:
Crucial POS Hardware 

Register screen: Standard monitor that displays the product database. Enables other functions, such as employee clock-in and viewing sales reports. Tablets—especially iPads—are popular for replacing bulkier monitors.

Barcode scanner: Automates the checkout process. Scanning barcodes pulls product info and adds it to the checkout total. Barcodes, when scanned, may also integrate with inventory management systems to automatically adjust stock levels.

Credit card reader: Secure and EMV-compliant credit card readers are extremely important for retailers and non-compliant retailers face potentially huge losses on account of fraud liability.

Receipt printer: Email and text receipts are gaining popularity, but paper receipts are still important for providing customers with a quick snapshot of their purchase. You can print employee sales totals, hours and other information.

Cash drawer: It may fade away in the years to come, but cash is still king. And as long as it is, you need a secure place to store cash for transactions. Additionally, there are no credit card fees tied to accepting cash.

Retailers benefit greatly from the automation and organization POS hardware and software systems provide. However, it’s also important to understand how these components work together to help you overcome certain pain points.
