Classification Of PDA And Business Mobile Business Function

      PDA Barcode scanner, barcode scanner is divided into many kinds, now the newest product is PDA barcode scanner. Common flat-panel barcode scanners are generally composed of light source, optical lens, scanning module, analog digital conversion circuit and plastic shell. It converts the detected optical signal into an electrical signal by means of a photoelectric element, then converts the electrical signal into a digital signal to be processed in the computer by an analog digital converter. PDA

     When a image is scanned, the light is illuminated to the image and the reflected light travels through the lens to the scanning module, which converts the optical signal to the analog digital signal (that is, the voltage, which is related to the intensity of the light received), and points out the grey degree of the number. PDA

     At this time the analog-digital conversion circuit converts the analog voltage into a digital signal and transmits it to the computer. Color with RGB three-color 8, 10, 12 bits to quantify, both the signal processing into the above-mentioned digital image output.PDA

      If there is a higher number of quantized digits, means that the image can have a richer level and depth, but the color range has exceeded the human eye recognition ability, so in the range of the distinguishable for us, a higher number of bar code scanners scan the effect is the color cohesion smooth, can see more details of the screen.PDA

       Using Windows Mobiel System, the interface operation is simple, support keyboard and handwriting double input. In the conduct of business operations, you can through the product bar code, numbering, name, specifications and other methods of inquiry products. At the same time can also be a number, name, telephone and other ways to query customers. Using GPRS network, real-time connection with the server host, at any time to view the product inventory, various prices and the last price. Instantly check the new products and the goods that are not being taken.PDA
