Abstract: A multifunctional extractable card reading modular cartridge connectable to a wireless broad band network router comprises an adapter box; an extractable wide band router modular cartridge installed in the adapter box and having two connecting terminals. The two connecting terminals of the extractable wide band router modular cartridge are capable of being electrically connected to two connecting ports of a wireless extractable card reading route. A front end of adapter box further has a USB port and an IEEE 1394 port for connecting other external devices; the USB port and the IEEE 1394 port are extended into the extractable wide band router modular cartridge in the adapter box; and a rear end of the adapter box 2 is installed with a 2×5 port 21 and an IEEE 1394 port 22 for connecting external devices.

Abstract: A universal coupler device includes a housing for coupling to various computer facilities, a circuit board received in the housing, two IEEE couplers and two USB couplers attached to the circuit board, one or more processor devices coupled to the IEEE couplers and the USB couplers, and a coupling box having a coupler element for detachably coupling to a coupler member of the circuit board and having one or more sockets for plugging various card members, and for allowing various card members to be coupled to the computer facility with the coupling box.
