Smart POS

Half of what makes up a successful POS system is the software. Each POS system needs software with a simple user interface and complete functionality.

For the hardware, the most important piece is the central processing unit, or the CPU. The CPU is the main terminal of the POS system and runs the software. Its operating system serves as the brain of the whole system.

The monitor is another key POS system component that illustrates sales information during the entire transaction. Operators can add items or view the price, tax, savings, subtotals, totals, or other crucial information.

The keyboard and mouse are also important. Some keyboards offer a built-in card reader. Other systems just use regular keyboards and computer mouse, but some don’t. Touch-screen monitors don’t require a mouse, but they may still require a keyboard for faster data entry.

This feature is more common with retail stores, but the customer store display informs customers of their subtotal and total price. It’s not required for most POS systems.

Receipt printers connect to the back-office server, monitor, and front house terminal. It prints a record of the transaction for the merchant and the customer.

This is a standard piece of POS hardware. One of the first components people imagine when they think of POS systems is the credit card reader.

Likewise, barcode scanners are an essential component of retail stores and grocery stores. They vary in size and technology, ranging from small handheld scanners to large industrial-sized check-out scanners.
