Abstract: This invention is a “Wireless local network financial system facility”. It is device for identifying the real identity of a person and thus to prevent credit card frauds. The system consists of a card access portion, two palmprint-identifying portions and a wireless local network card. When a user withdraws cash through the card access portion, the palmprint data of the user will be identified at the same time. Besides, the data will be sent to a financial center database to identify the identity of the user. Only the check is approved, the procedure of card access and withdrawing cash just can be finished. Therefore, the rights and the liabilities of stores and banks can be secured, and all meaningless loss can be protected.

Abstract: This creation is a “contactless charging device” with regard to a new contactless type and is applicable to the chargers for packaging and rechargeable batteries. The charger in itself is equipped with an ultrasound waves oscillator, in which the circuits is made output to an emission resonator to produce a powerful magnetic field and to radiate to the surrounding area of the charger. Moreover, within the battery packet charged is installed a receiving oscillator. The two sets of the oscillators resonate and induce the powerful magnetic field in the surrounding area of the charger and then a conversion is made into voltage and current, which are directly charged into the battery body in the battery packet. In this way, a charging effect is completed.

Abstract: This invention is a “mobile phone's wireless hand-free handset built in the battery packet” and can particularly resolve the harassing problem found in the wired send/receive signal box of a cell phone; it is to insert a low power radio frequency send/receive module into the battery packet of a cell phone and the power of the battery packet is to supply the voltage required for the work; and through the connection port of the battery packet and the cell phone, a voice signal is inserted; and the regulation of the input/output of the voice signal is made in the radio frequency send/receive module and then the signal is sent into the air at an extreme low power; and at the same time, another radio frequency send/receive module is installed in a wireless headset to construct a signal communication network with the low power radio frequency send/receive module in the previous battery packet so that a simple and easy operation of a wireless hand-free handset of a mobile phone is completed.

Abstract: A “wire keyboard with a receiving end for wireless transmission” is to use a receiving end circuit provided with a wireless transmission function and incorporates as the same circuit board with the circuit of the wire keyboard body and, after modulizing the electronic network of the receiving end with the wireless transmission function, to incorporate as a single circuit board with the circuit of the wire keyboard body in an inter-link. It is arranged in the interior space in the keyboard frame in order to reduce the manufacturing cost and can resolve a nagging problem of where to place the receiver.
