The app helps super in capturing inventory, whether for inventory, or for the acquisition of private collections. One can even set up the necessary columns for an Excel chart and modify or use the supplied base table. The order of the fields you can also define themselves, so that the collected data is optimally imported into other programs and can be reused. Scan barcode, enter number, designation and ready, then just keep sending the captured data such as e-mail. There are expensive inventory scanner for several hundred euros - the app for 2.50 they fully replace. Thumbs up !! Very useful and highly recommended, both personally and professionally.
