The present invention relates to a communication system, an information processing apparatus and method which enable communication setting to be performed through easy operations. An access point 11 has communication setting information for allowing wireless communication to be performed between a terminal apparatus 13 and the access point 11. The communication setting information is supplied to a tag 12 through contactless communication at close range between an IC tag reader/writer 21 and the tag (IC card) 12 and stored therein. When the tag 12 is put over an IC tag reader/writer 31 of the terminal apparatus 13, the IC tag reader/writer 31 reads the communication setting information from the tag 12 and stores it. The terminal apparatus 13 performs setting for communicating with the access point 11 based on the stored communication setting information and then performs wireless communication with the access point 11.
