Abstract:
1. Process to limit, through at least one processing and memorizing unit, the possibility to transform T X -type data into T Y -type data and the possibility to transform T Y -type data into T X -type data, the transformation of the T X -type data into T Y -type data being carried out using an A-type transformation function (F A ), while the transformation of the T Y -type data into T X -type data is carried out using a B-type transformation function (F B ), inverse of the A-type transformation function (F A ), the data being in particular designed to constitute for instance, pre-payment tokens, and being implemented on at least one data processing system, said process comprising: using an A-type data processing system (STD setting up at least once, at least one link (L) between the A-type data processing system (STD during an A-type customization phase, creating at least one A-type processing and memorizing unit (UTM during an A-type transformation phase: during a B-type customization phase, creating at least one B-type processing and memorizing unit (UTM and during a B-type transformation phase:
