Make invoices verifiable before payment. Each invoice carries a short Seal code. Your customer types seal.lifaio.com/doc, enters the code and selects the received file. It is checked in their browser, never uploaded. The result states: authentic, does not match, cancelled, replaced, expired or unknown code.
Open a fileAsk for an email carrying a Seal code. Open seal.lifaio.com/email yourself, then enter the email's code, your address and your personal Seal code. Check the result and your phrase, colour and word before acting. A verified code does not establish that a requested payment is legitimate.
