Worried about privacy incursion? Hiding from the government? You may want to steer clear of some San Francisco bars!

A new facial detection technology called SceneTap has been set up in a number of SF locations with hidden sensors that “discreetly record the age and gender of the people entering and leaving.”

Whoa!

The idea is that, when club goers want to know what the crowd is like before they head out,they can log into SceneTap to see a clubs male to female ratios, average age, and number of occupants. What you used to count on texts from friends for can now be attainable through modern technology.

So far, there’s been some backlash against this new program. Although technically, clubs and bars can tally these stats by checking IDs at the door, these sensors can pick up your gender and age with out your consent. SceneTap claims to keep identities clandestine, but who knows who's watching.

CEO Cole Harper has attempted to address concerns with an open letter to San Francisco residents.
