In my country, we need to capture TIN so we can report input VAT and their corresponding TIN. A TIN, may is from 9 to 12 digits and each receipt has its corresponding TIN. What we currently do is a cleark types every TIN on excel before we submit input VAT to the TAX bureau’s system. If TIN scanning can be done via ZOHO, this will save us a lot of time. I have a hunch that the same process exist in other countries and that will make your app very versatile.
