any act other than paying the money specified; The instrument must be payable to bearer or to order. The latter requirement is referred to as the "words of negotiability": a writing which does not contain the words "to the order of" (within the four corners of the instrument or in endorsement on the note or in allonge) or indicate that it is payable to the individual holding the contract document (analogous to the holder in due course) is not a negotiable instrument and is not governed by Article 3, even if it appears to have all of the other features of negotiability. The only exception is that if an instrument meets the definition of a cheque (a bill of exchange payable on demand and drawn on a bank) and is not payable to order (i.e. if it just reads "pay John Doe") then it is treated as a negotiable instrument. UCC Article 3 does not apply to money, to payment orders governed by Article 4A, or to securities governed by Article 8. Negotiation and endorsement Persons other than the original obligor and obligee can become parties to a negotiable instrument. The most common manner in which this is done is by "endorsing" (from Latin dorsum, the back + in), that is placing one's signature on the back of the instrument—if the person who signs does so with the intention of obtaining payment of the instrument or acquiring or transferring rights to the instrument, the signature is called an endorsement. There are five types of endorsements contemplated by the Code, covered in UCC Article 3, Sections 204–206: An endorsement which purports to transfer the instrument to a specified person is a special endorsement – for example, "Pay to the order of Amy"; An endorsement by the payee or holder which does not contain any additional notation (thus purporting to make the instrument payable to bearer) is an endorsement in blank or blank endorsement; An endorsement which purports to require that the funds be applied in a certain manner (e.g. "", "for collection") is a restrictive endorsement; and, An endorsement purporting to disclaim retroactive liability is called a qualified endorsement (through the inscription of the words "without recourse" as part of the endorsement on the instrument or in allonge to the instrument). An endorsement purporting to add terms and conditions is called a conditional endorsement – for example, "Pay to the order
