The present invention relates to a selection method, a selection system, a selection device and a recording medium. The downstream server stores product information on radio frequency (RF) tags output from the reader / writer into a database. The processing unit executes various processing using the product information stored in the database. If product information necessary for the processing unit to perform various processes is not stored in the database, a transmission request for product information is output to an upstream server. The upstream server sends the product information stored in the memory unit to the downstream server. The upstream server stores the history of received transmission requests for product information in a history database. The upstream server determines the prioritization of product information based on the history stored in the history database. The upstream server outputs a predetermined number of pieces of product information with the determined higher priority ranking to the reader / writer as information to be written on the RF tag.
