线下付款码支付

目前支付宝和微信都支持线下付款码支付，前提是商家POS系统必须包含可以读取条形码的扫码枪，POS系统需要将条形码转换为数值。

商家扫购物者手机钱包应用程序中显示的条形码，POS应用程序在发起付款请求的时候将此条形码数据发送给 PingPong 进行处理。

支付流程

1. 用扫码枪扫购物者的条形码。

2. 将条形码数据转换为数值，以便在付款请求中传递。 例如，数值包含：

• 支付宝16-24位。
• 微信支付18位数字。

条形码码值查看如下图所示：

备注：微信支付沙箱测试需要使用真实的微信钱包条形码码值进行测试。

3. 发起付款请求，调用 下单并支付接口，在paymentMethod对象中额外指定：

• paymentMethod.type：支付方式
• scanCodeId：条形码码值
