为何支付宝与微信离线状态也能支付？原因出在这！
得益于国内先进科技的不断进步，使得我们逐渐踏入了无现金时代，如今的吃喝玩乐我们都只需要通过一部小小的手机就能轻易实现。支付宝和微信可以说是人们最为常用的移动支付方式了，一众商家为了推广这一产品陆续出台相应的优惠活动。相信用过支付宝或者是微信向商家进行支付的朋友们，一定也有发现我们在信号不好的地区，甚至在断网的情况下还是能够进行离线支付，这又是为何呢？
相信很多人还是弄不清究竟是有何奥妙之处，毕竟平时我们使用手机、电脑都是通过网络传输数据的，但是在手机没有联网的情况下，不是应该感应不到才对吗？除了支付宝，使用微信乘车码支付费用的时候，也是出现了先显示成功后续才会扣款，这又是为何呢？接下来让笔者带领大家一起详细地讲解这一缘由吧。
首先，笔者要明确告诉大家一点，就是我们出示给商家的支付宝二维码，在如今已经实现了无需依靠服务终端器连接网络才能够生成。笔者猜测可能是马云出于大家对网络资费问题的担忧，于是"暖心"地给大家完美解决了这一问题。
当我们在打开支付宝的时候，系统就会自动向服务器方面申请令牌指令，如果是在没有网络的情况下，平台会生成一个离线代码的二维码，为了安全起见支付宝会给每个人都提前设定独立的身份作为种子数据，这样一来我们只需要将离线二维码给商家的扫枪扫描，就可以达到付款的目的。与此同时，系统还会自动检测支付环境，以及支付的金额是否足够，收款方也就不怕会出现扣款失败的情况了。不过需要注意的是，虽然我们能够使用离线的二维码，但是商家所使用到的系统就必须要有网络支持，否则的话扫码枪还是会无法识别二维码。
简单来说，支付宝的离线二维码对我们也不会构成安全隐患，因为这个二维码一般只能在几分钟内有效，而且每次点入都会重新刷新，这样一来即使这一付款码被盗取也不会出现扣钱的情况。
当然，除了支付宝的离线二维码，微信方面也有一种独特的支付模式，就是双方都处于离线的状态下依旧可以使用。因为当今实名制的普及，人们在众多软件都需要通过身份认证，因此想要利用软件来逃脱费用是不存在的。
至于微信，它能够支付滴滴、地铁或者公交，而且可以保持双方都是在离线状态下进行。这时候扫码记录成功后就会显示扣款成功，但是微信钱包的钱不一定会立即进行扣取，因为价格在一两块之间，所以微信方面在后续会不断提醒用户需要扣钱付款，系统也会自动记下每一笔钱，不用担心用户忘记的情况发生。
如今这种新颖的离线方式可以说给大家带来了极大的便捷。你又是否有尝试过离线进行支付呢？欢迎在下方评论留言你的看法与见解~
