Inventory is a program that lets users collect inventory and weight data simultaneously. The app can perform as a standalone sample collection platform but is also compatible with Elane USB scales. These scales can be plugged directly into Android devices with USB OTG functionality. A USB hub can be used to allow both a scale and barcode scanner to run at the same time.
A built in tutorial provides instructions on how to navigate and use the app. Metadata is collected with each record and includes the name of the person collecting data and a timestamp. Files can be exported as a flat CSV file or structured SQL file that will update a database table by deleting the current boxes and replacing the information with the collected data.
