Usually, a self-service cash register is equipped with one or two weighing modules, depending on its size and users’ needs. Weighing modules are used to weigh goods that customers buy to determine their cost based on mass.
There are different types and arrangements of self-service cash registers: small ones that contain one weighing module for measuring the weight of products up to 30 kg; and large ones with two weighing modules, providing product weight calculations from 30 to 60 kg. However, the specific characteristics of cash registers may differ depending on the manufacturer and model.
