1 - What does it show in the payment statement (invoice, bill) after payment?

Answer

It does not show anything related to ' tracking', or PCA. The text will be shown in bank/credit card statements depending on where you are because the payment will be made directly to our distributor/re-sellers. (Of course, I do not write here).

Just, for example, it will show as 'APP MOBI' / 'SOL', 'GUS', 'AFFI', 'AVANG', 'Askn', etc.
