微信默默增加的新功能 你也会用到
从微信改版以来，功能增加了不少，前面已经介绍过很多，就不一一介绍了
先来分享一条新鲜新闻：
一小伙和网恋女友恋爱两年，先后转了105万给对方，后来被拉黑了，警方一调查才知道所谓的女友竟然是个22岁的无业男…
105万……男……信息量也太大了点，交往两年连个电话都没打过，这爱情纯粹得让博士难以置信啊。
一般这种新闻一出，看热闹不嫌事大的网友都会在评论区调侃一番，明明是一件挺惨的事，愣是一路冲上了热搜，连支付宝官方微博都来凑热闹了。
不知道微信支付的产品经理看到会作何感想
最近，微信官方开发上线了一个小程序，又一次扩充了微信支付的适用范围。了解了一下之后，居家旅行必备的博士决定立刻分享给你们，因为它确实有点用。
如果你上学或者上班需要挤公交和坐地铁确实挺实用
其实腾讯早就推出过相似的功能——【腾讯乘车码】，和支付宝的刷码乘公交的使用方法一样，在手机上随机调取一张二维码，对准公交上的二维码识别区“滴”一下就行。
而【腾讯乘车卡】就更强大一些，开通后就相当于在手机中内置了一张公交卡，能享受部分城市的公交优惠政策。
只要你的手机是有 NFC 功能的安卓手机，就能把手机当卡用，不需要调取二维码，直接将手机背面贴近刷卡区就可以了
科普一下什么是NFC
这个问题解释起来有点复杂，说简单点其实就类似蓝牙，是一种无线的近距离传输模式。它能读取和模拟多种卡片，就比如公交卡。
大部分安卓新机都搭载了 NFC 功能，你也不用特意检查自己的手机有没有这个功能，只要点进小程序，系统就会告知你能否开通乘车卡。
苹果用户对不起，你们的 NFC 只支持 Apple Pay ，就算你们取关我也只支持 Apple Pay
因为这个小程序刚上线嘛，自然要搞一些活动，所以开卡费是不要钱的。
什么时候开始收费博士也不清楚，反正现在只需要充值十块就可以正式开通使用
目前有210个城市开通
开通使用后，这张万能的卡就帮你免去了出门忘带卡、卡里没充钱的尴尬，去其他城市旅游也不需要到处换零钱或排队买票了。
打开手机网络，打开 NFC 功能，打开【腾讯乘车卡】小程序界面，就能把手机当公交卡用。
温馨提醒一下各位华为、小米、三星用户：
你们的手机里有自带的钱包，一般被设为默认支付钱包，如果需要使用【腾讯乘车卡】，就需要在 NFC 的设置中选择【HCE 钱包】。
目前看来，微信在公共交通服务上的进程似乎比支付宝更快了一点哦
