Abstract
In a scale with a weighing cell, which can generate weight signals representing the weight of a load each time something is weighed, and with a signal processing system which receives the weight signals and generates:weight data on the basis of the weight signals,information determined on the basis of the weight data such as purchase prices, and/orweighing data containing identification data designating the weighing operation or group of associated weighing operations in question,an elaboration is proposed, according to which the signal processing system has an encryption unit, which can generate encryption data on the basis of at least some of the weighing data, where the signal processing system can transmit a data record containing at least the portion of the weighing data used to generate the encryption data together with the encryption data.
