I don't want to be this guy, but how come this can a good idea in post-snowden world?

Obviously you don't want your face associated with a political events or ideology events. But also and more surprisingly to tech events, specially crypto, physics and nuclear stuff. Some people get denied US tourist visa based only on that.

Aren't most tickets already associated with your name and credit card number anyway? Is adding your face tot he mix a serious problem?

I would say so.

You are adding biometric data to this so you can't say it's not me or type fake information. It's a similar issue with the Iphone Fingerprint ID. If you are making illegal calls, you can't say it's not me because 20 secondes before the call you unlock your cell with your own finger.
