Problems solved by technology
However, so far, the applicant has not seen any products or related patent documents that install a fingerprint sensor on the body of the wireless computer peripheral device and transmit the image to the computer device for comparison in a wireless manner. The main problem is that the current sliding fingerprint The sensor needs to transmit a considerable amount of data to the host system, causing the user to wait for several seconds to tens of seconds (depending on the type of wireless transmitter used), and the existing technology cannot effectively overcome this problem.

Embodiment Construction
[0057] image 3 A block diagram of a computer wireless peripheral device according to a first embodiment of the present invention is shown. Such as image 3 As shown, the computer wireless peripheral device with a sliding fingerprint sensing chip in this embodiment includes a peripheral device receiving module 20 , a peripheral device body 30 and a sliding fingerprint sensing chip 10 . The peripheral device receiving module 20 is connected to a host system 40 by wire, and has a radio receiver (which may be included in a transceiver) 22 . For example, the peripheral device receiving module 20 is connected to the host system 40 through a Universal Serial Bus (USB) interface, a PCMCIA interface, a PCI Express (PCI Express) interface or an IEEE 1394 interface. Host system 40 may be a computer, cell phone, personal digital assistant, or the like. The host system 40 utilizes its CPU 42 to process and identify fingerprint data, and activate at least one application program in the ...
