What hardware do I need for a POS system?
There is no simple answer to the question of what hardware you need for a POS system. The only direct answer is “it depends”. Each business has different needs – from the specific peripherals that compose their systems, to the number of terminals and the configuration of their network. The potential peripherals that you may need, depending on the type of business you run are listed below. Each item has a link to a page with more information about that device.
All peripherals can be bought separately, but it is usually a good idea to buy all in one systems to meet your needs and to ensure that all the devices are compatible. In some cases you may want to start with the basics, and then add on as you become experienced. It is important to know up front that your core system will be able to handle those add-ons when the time comes.
There are a number of hardware device communication protocols that are standard in the POS industry. It is important to know that your core system software supports the protocols that drive the peripherals you buy. Your vendor should be able to help you with determining this information.
