For both, the USB and keyboard models you don't have to worry. For the serial one you'll have to write code to read the value and pass it to your application. I recommend that you specify the USB model when buying: notebooks doesn't come with external keyboard ports or serial ports anymore so if for some reason you need to test it with yours or take the reader to somewhere you might have problems with it. > you simple click in the field you want to enter into and the scanner types in > the barcode number for you. The better if the app puts the cursor on the correct field... Also remember that barcode readers can be programmed to "press" TAB / ENTER after reading. If you're on a web application this might submit the form instantaneously so take care with that. Most of them come with a default to "press" ENTER after reading the barcode. -- Jorge Godoy <jgodoy@xxxxxxxxx>
