汇票

It is a bill payable at sight.

那是一张见票即付的票。

Can you cash this postal order for me now?

你现在能帮我兑现这张票吗?

You need an official signature to validate the order.

你要有正式的签字,这张票才能生。

"An indorsement in blank specifies no indorsee, and a bill so indorsed ecomes payable to bearer."

无记名并不明被人，以此方式票，应成为以持票人为收款人票。
