Parts of a POS System

If electing to go with a point of sale system without a touch screen, the keyboard will serve as a primary interface to the POS system. Keyboards for a point of sale system can vary in complexity and technology. They range in choices from a standard 101-key model like you may have on your home PC to industry-specific POS keyboards. Grocery stores and restaurants may need special functions that only programmable keyboards can provide. When selecting a keyboard, consider the size, programmable key requirements, and magnetic stripe reader functionality.
