汇票

It is a bill payable at sight.

那是一见票即付的汇票。

Can you cash this postal order for me now?

你现在能帮我兑现邮政汇票吗?

You need an official signature to validate the order.

你要有正式的签,汇票才能生。

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

无记名背明被背人，以此方式背之汇票，应成为以持票人为收款人之汇票。
