Processor generation matters more than most retailers realize when they are comparing specs on a spec sheet. An Intel i5 chip handles multiple open applications and inventory lookups at once without lag, while older or lower tier processors can visibly hesitate the moment a store gets busy. Touchscreen response time matters just as much. A terminal that registers taps instantly lets a cashier move through a sale without double tapping or waiting for the screen to catch up.
Barcode scanners get chosen based on habit more often than need, which is why so many stores end up with the wrong type for their counter. The two main formats, handheld and tabletop, solve different problems, and the right pick depends on what is actually being scanned and how the counter is laid out.
Operating system choice affects daily use too. A Windows 11 Pro terminal gives staff a familiar desktop style interface and works with the point of sale software a business already runs, while Android based terminals suit businesses that want a simpler, tablet like experience. Neither is universally better. The right choice depends on what the store's software provider recommends and how the staff already work.
A label printer does a very different job from a receipt printer, even though both use thermal technology. A receipt printer prints one long strip per transaction. A label printer prints individual labels, often for pricing, product identification, or shipping, and it needs to handle a completely different volume pattern across a working day.
Connection type decides whether the drawer actually opens when it should. Most retail cash drawers connect through the receipt printer using an RJ11 or RJ12 cable,

The honest answer to what a POS system costs is that it depends entirely on which pieces a business actually needs, and pricing pages that list a single number rarely tell the full story. Terminal hardware alone can range from an entry level unit built for a low volume counter to a flagship terminal with a faster processor built for a business running multiple transactions a minute during peak hours.
