It is a bill of exchange that's been endorsed by a third-party. In this situation the "notary public" is called an accommodation party or accommodation endorser.

It's a type of bill that a business accepts as a form of payment, even if it’s not the original bill.

You could look at it like a gesture of goodwill because you can help out a customer who might be having some temporary cash flow issues. Instead of refusing the payment or insisting on cash, the creditor accepts an "accommodation" bill, which might be a promissory note.
