在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请实施例。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
图1为本申请实施例支付通信方法应用场景的示意图，本申请实施例的支付通信方法可由图1所示的电子设备100执行，具体可由电子设备100的处理器1003控制电子设备100执行。如图1所示，电子设备100包括第一接口1001、第二接口1002、第三接口1004和处理器1003。第一接口1001连接销售点POS(point of sale)终端101(也可称为POS机)，第二接口1002连接支付设备102，第三接口1004连接显示设备103。
POS终端101可以支持现金支付、刷卡支付的支付方式，可以配置有扫码枪用于扫描商品标签印刷的二维码，根据二维码确定商品信息，如价格、店内折扣、商品类别等，POS终端可以与销售管理系统(也可以称为POS系统，图1中未示出)通信，在用户购买商品支付完成之后，POS终端可以通知销售管理系统更新商品库信息和营业额信息，将售出的商品对应的库存进行相应数量的减少。
支付设备102可以支持至少一种支付方式完成支付流程，例如，可以是刷脸支付、指纹支付、扫描付款码/收款码等支付方式，每种支付方式需要支付设备102配置有对应的硬件模块，例如，刷脸支付需要支付设备102配置有摄像头，以用于拍摄用户脸部图像。支付设备102在获取到用户支付的身份凭证(如面部图像、指纹图像、付款码等)之后，根据用户的身份凭证与支付机构(图1中未示出)通信，以完成支付的交易流程，例如，支付机构可以是网上银行、支付平台等。
显示设备103可以是数码管显示屏，能够显示如商品金额、支付金额等。
电子设备100包括第一接口1001、第二接口1002、第三接口1004和处理器1003。第一接口1001用于连接POS终端101；第二接口1002用于连接支付设备102；第三接口1004用于连接显示设备103。电子设备100还包括存储器(图1中未示出)，存储器与处理器1003通信连接，存储器存储有可被处理器1003执行的程序指令，处理器1003调用程序指令，以控制电子设备100执行本申请实施例所提供的支付通信方法。
图2为本申请实施例支付通信方法一个实施例的流程图，可以在如图1所示的应用场景下实施。如图2所示，上述支付通信方法可以包括：
步骤201，POS终端101扫描商品的二维码，在预先存储的商品信息库中查找到与二维码对应的商品信息，例如商品的价格、类别、店内折扣等信息。可选的，如果二维码无法扫描，也可以通过POS终端101的操作人员手动的键入商品的数字标识码。此外，如果消费者购买多个相同的商品，POS终端101的操作人员也可以在扫描商品的二 维码之后，输入或选择该商品的件数，以避免多次扫描同一种类的商品。根据上述扫描或输入得到的信息，得到交易订单信息，交易订单信息至少包括商品的金额。
步骤202，POS终端101根据交易订单信息生成第一报文，将携带有交易订单信息的第一报文发送至电子设备100。POS终端101发送通信消息时使用第一通信协议，第一报文是符合第一通信协议的报文，第一通信协议可以是销售点对象连接与嵌入(Object Linking and Embedding Point of Sale，简称OPOS)协议，在配置有Windows操作系统的POS终端上通常配置有OPOS协议，OPOS协议是一种工业标准协议，在此不再赘述。
步骤203，电子设备100可以使用第一通信协议解析第一报文，得到第一报文中的交易订单信息，然后根据交易订单信息生成符合第二通信协议的第四报文，将携带有交易订单信息的第四报文发送至支付设备102。支付设备102使用第二通信协议接收信息，第二通信协议可以是通用串行总线-人机接口设备USB-HID协议，USB-HID协议是一种标准协议，在此不再赘述。
POS终端101在结算之前，可以多次重复循环上述的步骤201～步骤203，以使电子设备100将POS终端101确定的交易订单信息转发至支付设备102。
步骤204，POS终端101接收到结算指令，例如，操作人员可以在POS终端101的键盘上单击“结算”的按键，以向POS终端101发送结算指令。
步骤205，POS终端101根据结算信息生成符合第一通信协议的第二报文，将第二报文发送至电子设备100。其中，结算信息至少包括用于指示结算的提示信息，可选的，结算信息还可以包括结算的总金额。
步骤206，电子设备100接收到第二报文之后，解析第二报文，得到结算信息，进而响应于第二报文(或者解析第二报文得到的结算信息)，触发支付设备102的支付流程。一种可选的实施方式为，电子设备102根据结算信息生成符合第二通信协议的第五报文，将第五报文发送至支付设备102。或者，另一种可选的实施方式为，电子设备102解析第二报文得到结算信息之后，查找预先存储的、与支付设备102协议好的用于触发支付设备102执行支付流程的第五报文，使用第二通信协议第五报文发送至支付设备102。本申请实施例对用于触发支付设备102的第五报文的具体内容不作具体限制，与支付设备102预先协议即可。
步骤207，支付设备102在被电子设备100触发执行支付流程之后，执行支付流程。具体的支付金额可以根据之前获取到的所有交易订单信息汇总得到，也可是电子设备100将POS终端101发送的携带有支付金额的结算信息转发给支付设备102，本申请实施例对此不作具体限制。支付设备102执行支付流程一种可选的实施方式如图3所示，包括如下步骤：
步骤601，确定支付方式。支付设备102可预置有多种支付方式，如刷脸支付、指纹支付、扫描付款码支付、被扫描收款码支付等。确定支付方式的方法可是消费者对支 付设备102执行选择操作，例如，支付设备102可包括触控显示屏，用于显示多种支付方式，由消费者在触控显示屏上触摸点击选择一种支付方式。选择哪一种支付方式也可由POS终端101提供的信息确定的，例如，在POS终端101接收到结算指令之后，POS终端101的操作人员可询问消费者想要选择哪一种支付方式，确定之后由操作人员在POS终端101选择该支付方式，在结算信息中整合选择的支付方式，进而在POS终端101执行步骤205时，将携带有支付方式的标识信息的第二报文发送给电子设备100，由电子设备100将支付方式转发给支付设备102，使支付设备102能够确定选择哪一种支付方式。
步骤602，调用支付方式对应的硬件，采集身份凭证信息。身份凭证信息是消费者支付的凭证，身份凭证信息的具体内容根据支付方式的不同而不同，例如，如果选择刷脸支付，则身份凭证信息为拍摄消费者的面部照片。不同支付方式调用的硬件不同，例如，刷脸支付需要调用拍摄消费者脸部的摄像头，指纹支付需要调用拍摄消费者手指指纹图像的摄像头，等等。
步骤603，在采集到身份凭证信息之后，支付设备102与支付机构通信，支付机构将支付金额的款项由消费者的账户中划拨到POS终端101对应的账户中，完成交易。支付机构可以是银行、第三方支付平台等机构，本申请对此不作具体限制。
步骤208，在支付设备102执行完支付流程之后，根据支付信息生成第三报文，发送至电子设备100。如果第二通信协议是可以双向通信的协议，如USB-HID协议，则可以根据支付信息生成符合第二通信协议的第三报文发送给电子设备100。支付信息包括支付的记录信息，例如，支付信息可以包括以下的部分或全部信息：支付机构代码、支付机构签发的凭证(如数字签名等)、支付金额、支付时间，等等。
步骤209，电子设备100接收到第三报文之后，解析第三报文，得到支付信息，进而将支付信息转发至POS终端101。如果第一报文是使用OPOS协议发送的，那么POS终端101无法使用该协议接收信息，电子设备100可采用另一种通信协议将信息发送至POS终端101，例如上述的USB-HID协议。电子设备100可根据支付信息生成符合第三通信协议(如USB-HID协议)的第三报文，进而将第三报文发送至POS终端101。
图2所示的实施方式仅为本申请实施例提供的支付通信方法的一种可选的实施方式，图4为本申请实施例提供的支付通信方法的另一种可选的实施方式，可以在如图1所示的应用场景下实施，具体而言，POS终端101使用OPOS协议向电子设备100发送报文，电子设备100使用USB-HID协议向POS终端101发送报文，电子设备100与支付电子设备100与支付设备102之间可以通过USB-HID协议互相通信，电子设备100可以使用OPOS协议向显示设备103发送报文。
如图4所示，该支付通信方法包括如下步骤：
步骤301，收银员手持与POS终端101连接的扫描枪扫描商品A的条形码，在商品 数据库中查找到商品A的金额。
步骤302，POS终端101发送携带商品A金额的第一报文至电子设备100。
在执行步骤302之后，电子设备100执行步骤303和步骤304，需要说明的是，步骤303和步骤304的执行先后顺序不限定。
步骤303，电子设备100将商品A的金额发送至支付设备102。
步骤304，电子设备100将第一报文发送至显示设备103。
在执行步骤304之后，显示设备103执行步骤305，根据第一报文显示商品A金额。
步骤306，POS终端101接收到收银员键入的结算指令。
步骤307，POS终端101发送携带有结算信息的第二报文至电子设备100。
在步骤307之后，电子设备100执行步骤308和步骤309，需要说明的是，步骤308和步骤309的执行先后顺序不限定。
步骤308，电子设备100触发支付设备102执行支付流程。
在执行步骤308之后，支付设备102执行步骤310，执行支付流程。
在执行步骤310之后，支付设备102执行步骤312，将携带有支付信息的第三报文反馈至电子设备100。
步骤309，电子设备100将第二报文发送至显示设备103。
在执行步骤309之后，显示设备102执行步骤311，根据第二报文显示结算信息。
在执行步骤312之后，电子设备100获取到第三报文，可以执行步骤313和步骤315，需要说明的是，步骤313和步骤315的执行先后顺序不限定。
步骤313，电子设备100将第三报文携带的支付信息发送至显示设备103。一种可选的实施方式为，显示设备103使用第一通信协议，第一通信协议是POS终端101发送至电子设备100的报文所使用的通信协议，电子设备100根据第三报文携带的支付信息，生成符合第一通信协议的报文发送至显示设备103。
步骤314，显示设备103在接收到支付信息后，显示支付信息中的支付金额等信息。
步骤315，由于电子设备100与支付设备102之间使用USB-HID协议通信，且电子设备100使用USB-HID协议向POS终端101发送消息，因此，电子设备100可以直接将支付设备102发送的第三报文转发至POS终端101。
步骤316，POS终端101在接收到第三报文之后，解析得到支付信息，可以根据支付信息执行入库流程，也即，更新与POS终端101通信的POS系统的数据库，将POS系统中的商品数量和营业金额进行相应的变更。可选的，POS终端101还可以在接收到支付信息之后切换软件的界面，显示支付完成对应的界面。
需要说明的是，POS终端101在接收到结算指令之前，可以多次重复循环上述的步骤301～步骤303，以使电子设备100将POS终端101接收到的商品信息转发至支付设备102。为了进一步说明，可以参考图5所示的实施方式，说明上述的过程，如图5所示，POS终端101执行如下步骤：
步骤401，判断是接收到扫描的商品码或结算指令。
步骤402，如果步骤401确定扫描到商品码，则根据商品码查找对应的商品信息，进而根据商品信息生成第一报文。
步骤403，发送第一报文至电子设备100。
在执行步骤403之后，返回步骤401。
步骤404，如果步骤401确定接收到结算指令，则生成携带结算信息的第二报文，第二报文用于发送给电子设备100。
如图5所示，在POS终端101执行步骤403之后，电子设备100接收到第一报文，执行如下步骤：
步骤501，解析第一报文，得到商品信息。
步骤502，将第一报文携带的商品信息发送至支付设备102。
由上可知，在POS终端101接收到结算指令之前，POS终端101循环的执行步骤401～步骤403，例如，收银员在结算之前，用扫码枪逐个扫描多个商品，每一次扫描商品码之后，执行步骤402和步骤403，进而由电子设备100将商品信息发送至支付设备102，由支付设备102存储接收到的商品信息，直至在执行步骤401时，判断接收到结算指令，则执行步骤404，跳出步骤401～步骤403的循环。
目前的POS终端通常配置有OPOS协议的显示设备接口，以用于向显示设备输出商品金额、结算金额等信息，但是由于无法通过OPOS协议接收信息，因此，POS终端可以使用另一种协议：USB-HID协议来接收信息，POS终端可以使用USB-HID协议接收键盘输入的信息，本申请实施例提供的支付通信方法可以利用POS终端中通常已经配置的上述通信协议，从POS终端获取交易订单信息，并在接收到结算指令之后发起支付设备的支付流程，在支付设备支付完成之后，将反馈的支付信息转发至POS终端，可以实现POS终端和支付设备之间的双向通信，从而使得支付设备作为POS终端的外设，帮助POS终端完成收银的支付流程，不需要淘汰不支持某些支付方式的POS终端，可以在推广使用新型的支付方式的同时降低改造的成本，并能够减少人工操作的环节。
