Thank you for you respond.

Like I clarify above, Warehouse Manager App DO supports ITF-14 via a BlueTooth scanner on TC20. It just can not support via build-in scanner of TC20. Hope it can be implement on next version.

That means I DO NOT need to buy a TC20 that is on your compatible list. Just find any android device (os version 4.4 or later)

I knew how to use the wizard. Thank you, but NO. The problem is more that 80% of my inventory only have ITF-14 barcode.  It is impossible to create them. Mostly because of COST, TIME and  COMPLEXIRY for daily running.
