支付宝支付（三接口实现）--最新版本（2014-09-10）

1.关于即时到账接口

即时到账是基于买家对卖家的信任，自愿付款给卖家，一旦买家点击付款，款项就马上到达卖家的支付宝账户。安装此接口后，买家在下单后付款时，可以选择这种支付方式来支付货款。

2.关于担保交易接口

所谓担保交易，是由买家先付款到支付宝，支付宝收到买家付款后即时通知卖家发货，买家收到货物满意后通知支付宝付款给卖家。这样买家就不用担心把款直接付给卖家，卖家不给发货的问题，大大的降低了网上购物的风险。安装此接口后，买家在下单后付款时，可以选择这种支付方式来支付货款。

3.关于标准双接口

卖家安装此接口后，买家在下单后付款时，既可以选择及时到账付款，也可以选择担保交易付款(选择哪种决定权在买家)。
