It is a well known fact that the registration of purchases of fast moving goods is a difficult problem which requires automatization in order to reduce the efforts of the households which have to provide the information and to reduce the work of the research organization which is processing the data. It is clear that one would like to use procedures which avoid coding printing mailing punching and data cleaning as much as possible. A consortium of research groups has developed a complete automated system for information processing (CASIP) for this purpose which satisfies these requirements and some more (Saris 1994). In this paper the system is explained and it is compared with alternative systems designed for the same purpose.
