　　京华时报讯 据央广报道，在对第三方抢票插件进行屏蔽后，前天央广铁路12306网站又出新动作，将静态的验证码变成了不断摇动的彩色动态验证码，很多网友直呼“看不清”。同时，这一升级也影响到了抢票软件，多家抢票软件接近“报废”。

　　此前，12306网站使用的是静态验证码，字符清晰，且不分大小写。而新版验证码不但经常出现字符叠压的情况，验证码还在不断抖动，不少用户表示，想看清楚有点费劲。有购票者说：“它是会动的，左晃右晃还是彩色的，你得使劲看。不能说看不清楚，但就是很费劲。”

　　12306升级验证码的初衷是什么？对此，铁路总公司客服热线表示，“其他的软件和网站已经影响到旅客正常的购票顺序了，这个动态验证码就是要保障旅客正常购票。”

　　升级之后，一些带有自动填写验证码功能的第三方抢票软件直接瘫痪。
