A system to enable access information stored on a terminal device (cellular phone) to be utilized without imposing a load on a user when performing communications from a communication device (MFP). An address book on the cellular phone is opened (S101, S102), and a name of a communication destination and the access information are selected by use of the address book (S103 to S105). vCard-formatted data is created based on the content selected (S108), and the created data is transmitted to the MFP (S109). The MFP analyzes the vCard-formatted data received from the cellular phone (S201, S202), and the communications are performed by use of the access information contained in the vCard-formatted data (S203 to S216).
