①首先当然是在互联网上点击打开京东的官方网站，然后在琳琅满目的商品中选择我们需要的，然后在商品的右侧选择加入购物车，如图；

②点击以后在新的页面我们点击去购物车结算，然后就会跳转到结算的界面了，见下图；

③在该页面，我们往下拉动网页，然后就会在最低端看到一些支付方式，有优惠券、京东卡等方式；

④我们点击使用京东卡之后，就会弹出一个选项，其中要求我们填入卡的密码，然后我们将之前获得的京东购物卡密码输入进去；

⑤输入以后我们点击右侧的使用，然后系统会自动验证该密码的正确与否，如果正确的话，那么就会自动显示改卡对应的卡号，然后会提示我们是否绑定我们的京东账户，绑定以后再购物的时候勾选该卡就可以使用了，如图；
