The first component of a salon and spa POS system is the software. This is the brains of the operation, as it helps to manage all of the different aspects of the business.

The second component is the hardware. This includes the actual POS terminal, which is used to process transactions, as well as any peripheral devices that may be needed, such as barcode scanners and receipt printers.

The third component is the support infrastructure. This includes the server that hosts the software and the network that connects the different components. Without this infrastructure, the system would not be able to function.

These are the three key components of a salon and spa POS system.
