In April of 2003 the Metro Group – at that time located at the Extra Future Store in Rheinberg, Germany – started to introduce self-checkout registers in German food retailing. In October 2003 the rollout began in Ratingen near Düsseldorf. According to Uwe Pieper, at this point nationwide approximately 70 real,- hypermarkets are furnished with self-checkout counters. Yet sometimes equipment is also being taken down again. In this EuroCIS interview he talks about customers, configurations and cash register employees.
