此规范通过定义可以使用WFSGetInfo、WFSAsyncGetInfo、WFSExecute和WFSAsyncExecute函数发出的特定于服务的命令，描述了XFS下的Depository（DEP）服务提供的服务的功能。存管器用于接收媒体并将其存入设备或终端。主要有两种类型的存放处:一种是用于将介质存放在信封中的信封存放处，另一种是用于存放装有散装介质的袋子的夜间保险箱存放处。信封存放处接收介质，在介质上打印，并将介质存放在容器或箱子中。一些信封储户提供在交易开始时向客户分发信封的功能。顾客拿着这个信封，填好寄存介质，可能会把它记下来，放进投币口。然后，信封被接受、打印并运输到存放容器中。信封分发机构可以是具有相同进出口槽的信封存放装置机构的一部分，也可以是具有单独进出口槽的单独机构。客户分发和未携带的信封可以收回到设备中。当分配器是一个独立的机构时，信封会缩回分配器容器中。当分配器是一个常用的机械装置时，信封会缩回存物箱。夜间保险箱通常只记录袋子的存放情况，不在媒体上打印。

This specification describes the functionality of the services provided by the Depository (DEP) services under XFS, by defining the service-specific commands that can be issued, using the WFSGetInfo, WFSAsyncGetInfo, WFSExecute and WFSAsyncExecute functions. A Depository is used for the acceptance and deposit of media into the device or terminal. There are two main types of depository: an envelope depository for the deposit of media in envelopes and a night safe depository for the deposit of bags containing bulk media. An envelope depository accepts media, prints on the media and deposits the media into a holding container or bin. Some envelope depositories offer the capability to dispense an envelope to the customer at the start of a transaction. The customer takes this envelope, fills in the deposit media, possibly inscribes it and puts it into the deposit slot. The envelope is then accepted, printed and transported into a deposit container. The envelope dispense mechanism may be part of the envelope depository device mechanism with the same entry/exit slot or it may be a separate mechanism with separate entry/exit slot. Envelopes dispensed and not taken by the customer can be retracted back into the device. When the dispenser is a separate mechanism the envelope is retracted back into the dispenser container. When the dispenser is a common mechanism the envelope is retracted into the depository container. A night safe depository normally only logs the deposit of a bag and does not print on the media.
