Build quality and lock type are worth checking closely, since this is the piece of hardware that gets opened dozens of times a day for years. A metal cash drawer with a solid lock and an auto open or manual release that matches how the staff work is built for years of daily use, not just a quick unboxing test.

The practical change is in order flow, not just the format. A paper ticket sits in a fixed order on a rail, while a kitchen display system can group items by station, flag how long an order has been waiting, and update automatically the moment a server or counter staff member makes a change, without anyone walking a corrected ticket back to the kitchen.
Wired versus wireless is a separate decision from handheld versus tabletop. A wired scanner is simpler, has one less battery to think about, and suits a single fixed position. A wireless scanner gives staff the freedom to scan anywhere within range, which matters for larger floor plans, inventory counts, or curbside order fulfillment where the scanner needs to leave the counter entirely.
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.
A kitchen display system is not only for large restaurant chains. A busy independent kitchen or food truck running more than one order channel sees the same benefit from clearer order flow and less paper handling.

A slow checkout line costs more than a few minutes of customer patience. Every extra second per transaction adds up across a full shift, and during peak hours a sluggish terminal can turn a two person line into a five person line fast. The terminal itself, not just the software running on it, is usually the reason.
