In an information processing device, a first address adder generates a first address representing a target for write of data or a storage location of data to be read. Each spatial object has a location in an n-dimensional space. The number of times of downshifting within a predefined time is limited to a predefined number of times. Furthermore, an RF signal is communicated between the first substrate and the second substrate in a contactless manner through the thick pass-through slot. The number of segments and grouping of a customer population changes at different stages of the campaign.
