Abstract: A plug-and-play barcode scanner is plugged into an operable electronic apparatus, e.g. a computer or a portable electronic apparatus and after the plugging is completed, the plug-and-play barcode scanner is operative to scan a barcode. The plug-and-play barcode scanner is formed of a micro-scanner designed in combination with a plug-and-play transmission interface module, so that the barcode scanner tends to become more lightweight, more convenient and more practicable and is beneficial to the popularization of managing markets of commodity marketing and sales with the barcode in the future.

Abstract: A micro scan engine module is provided, which is used to scan and read barcode data. The micro scan engine module includes an outer case and a circuit board, in which the outer case is formed as an integral body. After the outer case and the circuit board are assembled, a complete scan engine module is formed. Through the integral design of the outer case, the errors during assembly the components are reduced, the working efficiency of the scan engine module is effectively improved, and the manufacturing cost is reduced.

Abstract: An environmental protection announcement system and an implementation method thereof are provided. The environmental protection announcement system includes an announcement device and an information carrier. The information carrier is capable of storing announcement information constructed by an information supply side, so as to enable a user to be in information connection with the announcement device through the information carrier and to drive the announcement device to change display content with a small current. In a normal state, the announcement device does not need an external power supply, thereby achieving the effect of energy saving.

Abstract: A barcode display device is disclosed to include a connection interface connectable to a host system, a microprocessor for receiving data from the host system through the connection interface and converting the received data into a barcode signal, a display screen, and a display drive control module for driving the display screen to display the barcode signal outputted from the microprocessor so that the user can scan the displayed barcode with a barcode reader and store the barcode data in a memory inside the barcode reader.

Abstract: A voice barcode scan device includes a barcode scan unit, a microprocessor, a memory unit, a voice-processing unit and a voice output unit. The memory unit stores different voice signals according to different addresses. The barcode scan unit reads the address from the barcode label and fetches the corresponding digital voice signals from the memory unit. The accessed voice signals are processed and converted to analog signals by the voice-processing unit. The analog voice signals are output from the speaker or earphones to achieve the voice education, entertainment or security purposes.

Abstract: A browser with barcode input comprising a barcode scan input device, a scan switch, an indication LED, a mobile phone output interface, an USB output interface, a LCD display, a keypad and a switch, all the devices are connected to a built-in microprocessor. The barcode scan input device scans the barcode format web site addresses and converts the data into digital signals; the digital signals are processed by a microprocessor and stored into memory. Several hotkeys can be pre-defined for the corresponding web site addresses. When a computer or a mobile phone is connected to the present invention, users can press the hotkey to activate the Browser for the desired web site address or run Outlook for E-mail contents.
