Can I cash a check if I wrote on the back?
如果我写在背面，我可以兑现支票吗？
According to the National Check Fraud Center: Section 3-206: If the back of the check says it is For deposit only, then has the signature of the payee, that is a restrictive endorsement and it should be observed, but the person who affixed that indorsement can waive it.
根据国家支票欺诈中心：第 3-206 节：如果支票背面写着仅供存款，则 有收款人的签名，这是一个限制性的背书，应该遵守，但贴上该背书的人可以放弃它。
