Cash Register Terminology

Here are some of the most common terms that come up in a cash register or POS conversation. They will help you understand the technical jargon during a POS demo or purchase evaluation.


Departments are numbered keys on the keyboard that represent a grouping or category of items (such as dairy products). They can be used for quick and accurate entries of items sold, but are usually used for tracking and reporting. The number of departments ranges from 8 to 99.

Price Look-Ups (PLUs)

Commonly referred to as PLUs, these are numbers that can be programmed to represent merchandise or inventory. They are used for quick and accurate entry and tracking of frequently sold items. Once programmed, the user punches in the PLU code (e.g. 99) on the keypad and then presses the "PLU" button. The product's name and price and any other programmable information will immediately appear on the display. The number of PLUs can range from 1 to 30 000 depending on the model. Certain models also allow the user to assign a name to each PLU number, so that each selected item has a name, price, and description all at the touch of a button.

Clerk Identification System

Most models have a clerk ID security system that gives clerks an individual ID number allowing them to sign in and use the cash register. This system serves as a tracking and reporting feature for individual clerk sales. Magnetic locks such as the i-Button or Dallas Lock identify the clerk based on the magnetic key he/she is using, when logging on.

Cash Drawers & Trays

All models come with at least 4 slots for coins and 4 slots for bills in the cash drawer. Higher-end models come with a few extra slot trays or an accessory drawer for additional storage of currency and/or checks.
