为什么超市的扫码支付，不用输密码钱也会被“扫走”？
随着我们的网络时代的来临，许店面都开始走上智能化，出门也都之带着手机就好了，如果需要付钱的话就拿着手机扫一扫就可以了。而支付的方式基本上都是支付宝或者微信。一般的小卖部咱们过去只要扫一扫对方的码然后输入密码就行了。但是大家有没有发现去超市买东西的时候都会不需要使用密码，收银员会拿着一把扫码枪对着你的二维码扫一扫就直接扣除了相应的金额了。大家知道这是怎么做得到的吗？对自己安全吗？
其实这几点大家都不用太过于的担心，因为超市的扫码枪是跟收银台连接在一起的，不是说随便怎么刷取的，而且如果你想要刷取支付宝或者是微信的二维码那么你就要向他们提交自己的资料以及进行申请。只有申请通过了，你的扫码枪才能使用去扫支付宝或者微信。而它的作用就像已经不太流行的pos机一个意思，都是经过读取对方信息进行交易的。
而且你在进行交易的时候最多只能支付1000元，如果超过了1000元就不能使用扫码枪进行支付，届时也就只能使用手动扫描的方式来进行交易了。而且我们的二维码其实也是非常安全的，咱们每一次的交易的二维码都是不同的，也就是说你进行2000次的交易都会出现2000个不同二维码图案。而我们刷商家的二维码就可以是固定的，因为我们手动刷二维码时需要输入密码的，这样安全性自然也就提高了不少。其实扫码枪真正用处就是可以省去支付时面临的密码输入的麻烦，既能提高效率也能节约时间。
所有说大家不用太多担心手机会被人偷拍过去刷钱，因为每次的二维码都只能使用一次，就算被拍走了也是无效的二维码了。不过小编提醒大家的是手动输入的密码，因为咱们的这个密码是固定，而且还是扫对方的二维码来进行支付的。如果你的手机被其他的盗走了，而且对方还知道你支付密码那就危险了，对方完全可以直接扫二维码进行转账。
所有大家还是要好好的保管好的自己的手机以及自己的密码，如果被其他人发现自己的密码要赶紧更换密码，以防出现不必要的麻烦。好了，小编今天分享到这儿，如果有其他问题欢迎在下方的评论区进行评论交流。
