inFlow Cloud for Android/iOS can be used to scan items in and items out, create and pick sales orders as well as create your products. They’re working on adding more functionality to the mobile app; in the meantime, you can also use a regular “plug and play” style barcode scanner with inFlow Cloud for Windows and Web.
inFlow works with a range of barcode scanners including ones made by Motorola, Metrologic, Symbol, and other Manufacturers. As a general rule of thumb, most “plug and play” scanners should work fine (i.e. USB connector or USB wireless receiver, plug it in, installs itself).
