A total of 72 cities in China are increasingly well connected through the use of a one-card pass as the country pushes for smart city initiatives, Beijing Youth Daily reported on Wednesday.

根据北京青年报周三报道，随着我国对智慧城市建设行动的推广，全国已实现城市一卡通互联互通的城市共计72个。

Card users can enjoy local discount preferences for public transportation¹ and make payments for goods and services. They can also use it to rent public bicycles and take subways in some member cities.

一卡通用户刷卡乘公交可享受当地折扣，还可刷卡购买商品和服务。在某些城市，一卡通还可以用于租公共自行车和搭乘地铁。

According to the IC card application service center at the Ministry² of Housing and Urban-Rural Development, 750 million IC cards have been issued, among which 150 million can be used in other cities that have joined the one-card pass system.

根据住房和城乡建设部IC卡应用服务中心数据显示，全国IC卡总发卡量达到7.5亿张，其中加入一卡通系统的1.5亿张可在其他城市使用。

The ministry launched the system in 2012, attracting eight cities -- Shanghai, Ningbo, Shaoxing, Huzhou, Taizhou, Changshu, Lanzhou and Baiyin -- to adopt the system by July that year.

该部门于2012年推出该系统，吸引了包括上海、宁波、绍兴、湖州、台州、常熟、兰州、白银八个城市在当年7月实现互联互通。

By 2015, more than 190 cities were undergoing preparations to join the system, including all four metropolises³ and 90 percent of provincial⁴ capitals, covering more than 700 million people.

截至2015年，准备加入到互联互通系统的城市已达190多个，涵盖所有4个直辖市和90%的省会城市， 覆盖7亿以上人口。

一个负责智能建筑及居住区数字化标准化的全国委员会介绍称，产品技术标准已于2015年7月发布，并于2016年2月正式实施。
