D 实验三关于第三方支付平台（2学时） 1、现在第三方支付平台的格局如何以及各自所占有的市场情况是多少？ 2、请同学上网查询目前主要的第三方支付平台有哪些?大的网上商城采用的有哪些?(列表说 明) 网上商 快钱易宝支付宝Paypal 财付通首信易城 淘宝√ 易趣√ 当当网√√√√ 卓越网银行卡 支付 拍拍网√你认为哪几家第三方支付平台最有生命力,会长期生存下去? 我觉得易宝的生命力比较强，会长期生存下去。 （1）如果消费者可以享受到：安全的在线支付，方便的电话支付，免费的会员服务，为您的手机充植，精彩活动积分奖励。 （2）可以为商户提供：网上、电话、汇款，多种收款方式，支持外卡，让你您的生意做到全球，7*24小时客服，技术支持快速反应，接入更简单，交易更安全，结算更及时！ （3）功能有：会员登录安全设置：通过验证图片、提示问题、常用机校验等手段实现的双向安全验证机制，确保用户在任意场所登录易宝网站时的安全。 快捷查单服务：消费者通过此项服务可以方便快捷的查到自己选择YeePay易宝支付的网上购物订单！商户通过接入“快捷查单”功能，为客户提供贴心增值服务，提升服务品质和形象！ 自主接入服务：商户可通过自助方式网上注册并使用易宝在线支付服务，不仅可以在线收款，而且还能登录商户系统进行定单管理和交易结算。依托易宝强大平台，确保安全交易，并享受7*24小时客户服务及快捷查单等增值服务。 3、第三方支付牌照的颁发会对现行的网络支付以及银联会产生什么样的影响？ 易观国际分析认为，牌照发放后，获得牌照的企业将可接入超级网银，第三方支付企业以提高企业资金周转效率的定制化解决方案，将会逐步向传统企业进行渗透，也将出现从单一产业链的支付服务向跨产业链的融合转移的趋势。支付企业通过整合各种支付产品，为企业进行深度定制化服务，加快资金周转效率，而保险、基金等行业将是一个新的蓝海市场。 一旦涉及到钱，那么这个庞大的支付产业必定摆脱不了银行的介入。在《支付机构客户备付金存管暂行办法(06.02会议征求意见稿)》出台前，仅有支付宝等少数国内第三方支付公司委托银行每月对客户的交易保证金做托管审计，其他公司则会依托三四家银行提供备付金托管与清算服务。而随着今年5月26日首批支付牌照正式发放，一场第三方支付公司挑

Unit3 The Computer 学习策划 How can we memorize new words effectively of each unit we are learning?Maybe this is a big problem for each of us,for in our new textbook there are too many new words for us to remember.Some classmates say new words cost them so much time,but still when they use them,they often forget or make mistakes.Don’t worry about it.It’s the same for every English learner.But in doing this,people are different from each other.Some people memorize new words quickly and correctly and can use them freely.First,they work hard at English,and second they may have some effective methods which they learn English with.I think the following might be of some help to you when you learn English. 1.Concentrate on your task while reading English.Don’t be disturned by other things. 2.Divide the new words you are learning into proper groups and put them down.Whenever you have time,such as early in the morning,just before sleep,read and remember them separately. 3.Learn new words by comparing and associating their pronunciations,spelling forms, collocations and styles,such as： advice n.—advise vt. drop in on sb.—drop in at a place enjoy his singing—enjoy him singing（informal） （4）Learn new words by analyzing word roots or affix,for example, comfort vt.—comfortable—uncomfortable discomfort vt.

第三方支付安全性及风险防范 一、第三方支付概念 第三方支付是阿里巴巴集团主席马云在2005年瑞士达沃斯世界经济论坛上首先提出来的，目前为止学术界还没有给出一个非常明确的概念。第三方支付是非金融机构从事金融业务的重要渠道，人民银行发布的《非金融机构支付服务管理办法》中将其定义为依托公共网络或专用网络，在收付款人之间作为中介机构，提供网络支付、预付卡的发行与受理、银行卡收单以及中国人民银行规定的其他支付服务的非金融机构。 从其形式上看，所谓第三方支付，就是具备一定实力和信誉的第三方独立机构提供的网络支付平台，它是以非银行机构的第三方支付公司为信用中介，以互联网为基础，通过与各家银行签约，使得其与商业银行间可以进行某种形式的数据交换和相关信息确认，实现持卡人或消费者与各个银行以及最终的收款人或者商家之间建立一个支付的流程。第三方支付通过其支付平台在消费者、商家和银行之间建立连接，起到信用担保和技术保障的作用，实现从消费者到商家以及金融机构之间的货币支付、现金流转、资金结算等功能。在网络交易中，买方选购商品后，使用第三方支付平台把货款支付给第三方，再由第三方通知卖家货款到达并要求卖家发货，买方收到商品并检验后通知第三方，由第三方将货款转至卖家账户。相对于传统的资金划拨交易方式，第三方支付可以对交易双方进行约束和监督，有效地保障货物质量、交易诚信、退换要求等环节，满足电子商务交易的安全性，为交易成功提供必要的支持。如支付宝、财付通等都属于此类平台。 与其他支付方式相比，第三方支付服务具有以下特征： （1）支付中介。第三方支付的具体形式是付款人和收款人不直接发生货款往来，借助第三方支付平台完成款项在付款人、银行、支付服务商、收款人之间的转移。第三方支付平台所完成的资金转账都与交易订单密切相关。 （2）中立、公正。第三方支付平台不直接参与商品或服务的买卖。公平、公正地维护参与各方的合法权益。
