×TecStore Explanation: PLUPLU (pronounced P, L, U) stands for Price Look Up. It is a traditional way of referring to a product record. It is a term carried over from early cash registers.

For example:
"Coca Cola Can 330ml" is a PLU
"Diet Coke Can 330ml" is another PLU and so on.

Note that the term refers to the product record itself, not the number of physical stock items. If you had 25 cans of Diet Coke Can 330ml in stock, they would still all be grouped under the same single PLU record.

Most devices or software have a memory limit on the maximum number of PLU records that can be stored.

A PLU key or Direct PLU key refers to a button (either on a keypad, keyboard or touchscreen) that is linked to a specific PLU record. For example, if your device or software had 5 PLU keys, then they may be labelled Apples, Oranges, Bananas, Grapes, Onions.
