预付费电表常见的两种预存方式

Release date: View count:254

预付费电表常见的两种预存方式;

预存方式有两种,一种为代码式,一种为写卡式。

1、代码式原理为:管理系统将用户信息和购电信息结合起来生成一组加密代码,通过电脑或者手机APP充值软件远程将加密代码输送到电表中,

或者将其交给用户自己到电表上输入,电表经过正确解密后得到预存电量或金额并保存。

2、写卡式:将预购电量或金额写入专用电子卡中,交给用户持电子卡到对应电表上进行通讯,预购值自动送入电表中。

电子卡又称IC卡,也称购电卡,都是由专用的IC芯片经过特殊封装后而成,常见购电卡按通讯方式分为接触式和非接触式两种。
