Abstract: The present invention is a card reader, which includes an upper case, a lower case, and a printed circuit board. A terminal part and a memory card terminal part are directly formed on the said printed circuit board. Utilizing the structural design of directly forming USB terminal part and memory card terminal part on the printed circuit board, which is different from the method of the conventional card reader that welds various terminal connectors on the printed circuit board, the area used for allocating connectors on printed circuit board is saved, and the manufacturing cost is accordingly decreased.

Abstract: This invention is a connecting device for wireless communication. The said connecting device is primarily installed in a mobile phone to enable transmission and reception of message between both sides for communicating, in which the said connecting device utilizes the connecting technology of the Bluetooth or the public channel to enable end-to-end connection or multipoint connection, and thereby to enable transmission and reception of message. It also allows allocating an independent base station on a car or at a fix location for receiving and transferring message to relax the distance constraint of wireless communication and to support the function of hands-free.
