The present invention concerns a method for producing pavements for outdoor facilities, the surface finishing material used therein, and the pavements for outdoor facilities obtained thereby. The second data processing device generates an encrypted input mask and transmits it to the first data processing device which displays it. A plurality of data buffers is provided for writing or reading data between said memory storage array and the system chip within the single semiconductor package. The storage options of the second storage system may include one or more storage devices available to the second storage system. The second switching signal and the third switching signal have the same switching frequency, and have a predetermined phase difference between the phases of the two switching signals to cancel and remove an amplitude modulation component included in the frequency modulation signal. The second slot is disposed above said first slot so that the inserting direction of said first IC card and the inserting direction of said second IC card are mutually in vertical relation.
