Price calculating retail scales
In order for a retail scale to be approved for use, it is required that it must be type-approved according to OIML Class III and first time verified. This applies for the weighing to be approved as the basis for financial transactions and is primarily about consumer protection. A price calculating retail scale must always have 3 displays, weight, unit price and total price. The consumer must always be able to see the display. Distinctive for a price computing scale, POS (Point Of Sale) is that it has an approved communication protocol and can be connected to cash registers.
