Abstract: An ultrahigh frequency (UHF) radio frequency identification (RFID) reader with sighting function for reading RFID tag is mainly formed by a RF antenna and a controller, wherein the physical appearance of the RF antenna is formed with a sighting portion. In reading operation, users can aim the sighting portion of the RF antenna at a RFID tag at a remote location by visual mode so that the RF antenna can finish the reading operation promptly and accurately. Therefore, the reading accuracy and efficiency and power consumption can be improved.

Abstract: A mobile barcode information reading system is composed of a mobile electronic device and a portable barcode scanning device. After the mobile electronic device completes information linking with the portable barcode scanning device, an operator can operate the portable barcode scanning device directly on the mobile electronic device. Therefore, the implementation of the present invention is not restricted by application site. Furthermore, a barcode information obtained can be saved and displayed directly on the mobile electronic device.
