Around the world,facial recognition（FR人脸识别）has slowly become a part of our daily life.

After helping people to make payments and open bank accounts,FR now is used in the subway of Zhengzhou,Henan Province. FR was introduced in September and now it can be used by passengers who link their online payment systems to the subway's smartphone app. China Daily reports that other cities in China,including Beijing,are testing a similar system.

It's not hard to see why. FR technology could help speed up security （安全） checks greatly. Yuan Xiaoqin,a park manager in Hangzhou,told CCTV the reason why the park upgraded （升级） its entry system,"FR can help a visitor enter the park in two or three seconds. Fingerprint information sometimes isn't sensitive （灵敏的）,especially when the fingers are injured or too dry." Before,the park used a fingerprint entry system.

However,there are some problems with the use of FR. Some people are afraid that their personal information will be leaked.

In fact,sometimes people can refuse the app if they don't want their facial information disclosed （暴露）,but sometimes people don't have a choice.
