Hi, this is my first look to a MK590 I create an asp.net web page with a textbox where I would need to insert the barcode from the scanner to search it in an access database. I dont understand  the philosophy of this instrument. I expected the scanner starting when the barcode is near the sensor and next the code will be 'inserted' in the textbox, like a simple scanner keyboard emulator, or one of hardware buttons activate the scanner. I hope somebody can help me. Regards Lenny
