Barcode scanning device suggestion from you which will show details of the stock which was scanned. 3. When barcode is scanned in delivery mode, its inventory to be reduced automatically. 4. A technique or device to measure my material which is stone tiles accurately. Since these tiles are not always in regular rectangular or square shape so their best estimate area in [login to view URL] has to be taken by my calculation method. For this, I need an industrial grade device. You can suggest any already in market or something that has developer kit with it so we can integrate. Please suggest your best pricing and give proper bid pitch. Only serious bidders and fully experienced persons. Thanks.
