Barcoding is available in the paid Enterprise version for businesses. In this version we activate the phone or tablet camera to scan barcodes. In the free version, you can identify tools by their serial number or any other unique identifier. You should include this unique number in the tool description or title for quick search and access. For example, if you own 10 circular saws, the title could be "Circular Saw 01" for the first one and so forth.
