Well, at least you can protest about it.

In China, collecting your bio data is more like a procedure than a choose.

For example, I renewed my citizen ID card few weeks ago, and got my facial and fingerprint collected.

Also, some companies like Alibaba are helping the data collection: https://www.engadget.com/2017/09/03/alipay-facial-recognitio... and http://www.solidot.org/story?sid=47235 (In Chinese)

I believe all those data will be used to help tracking people.
