  1. Register items.

  2. - Print QR codes and paste them on your store, your menu, somewhere, - somehow. -
    3. -
  3. - Clients scan the QR codes and get information about the items plus the - price on their phones directly (they must have internet) -
    4. -
  4. - Once they decide to pay, they'll get an invoice on their phones - automatically -
    5. -
  5. - When the payment is confirmed, a confirmation code will be issued for - them. -
    6. -
-

- The confirmation codes are words from a predefined sequential word list. - Each new payment bumps the words sequence by 1. So you can check the - confirmation codes manually by just looking at them. -

-

- For example, if your wordlist is - [apple, banana, coconut] the first purchase will be - apple, the second banana and so on. When it - gets to the end it starts from the beginning again. -
