Blank endorsement
（重定向自Blank indorsement）
Blank endorsement of a financial instrument, such as a cheque, is only a signature, not indicating the payee. The effect of this is that it is payable only to the bearer – legally, it transforms an order instrument ("pay to the order of (the payee)") into a bearer instrument ("pay to the bearer"). It is one of the types of endorsement of a negotiable instrument.
