Ferengi Seal of Dismemberment

From Memory Alpha, the free Star Trek reference.

The Ferengi Seal of Dismemberment is a Ferengi mark of authentication that is affixed to the vacuum dessicated remains of Ferengi individuals.

The Seal serves as a certification for any disc of dessicated remains, providing a nominal guarantee that the remains in the disc are those of the Ferengi they purport to be. Because the remains of some Ferengi are prized as collectibles in that society the presence of the Seal can increase the value of the discs. (DS9: "The Alternate")

Not all vacuum dessicated remains seen have been marked with the Seal and it is possible that such authentication is only done under certain circumstances or by certain agencies such as the Ferengi Health Commission. It is almost certainly a fee-based process.
