Targhetta di cartolina vaglia

[magsworld]

I don't quite understand what the "targhetta" is on a "Cartolina vaglia" - assuming that cartolina vaglia is a money order of some kind, what would the "targhetta be? The "stub" - in other words, where a receipt that gets torn off to show that you did buy a cartolina vaglia with a certain serial number (if they had them). These legal documents are constantly referring to the targhetta. Here is a shot of the words in the document. Thanks for any advice.
