The guillotine is a machine used to execute people by decapitation (chopping off their heads). A guillotine is made of a heavy blade attached to a rack, which moves up and down on a vertical frame. When the rack is let go, it will fall down and the blade will cut the convict's head off.
A national producer number, or NPN, is a tool to protect individual insurance agents and agencies from identity theft and fraudulent representations made to the National Insurance Producer Registry, or NIPR.
The NPI (National Provider Identifier) is the only health care provider identifier that can be used for identification purposes in standard transactions by covered entities. The Health Insurance Portability and Accountability Act (HIPAA) requires that covered entities use NPI numbers in standard transactions.
