They recently streamlined their API to make it easier to use.
Also, Kairos has a non-API product, called TimeClock, which allows people to punch into work using their face. Could be a competitor to http://www.producthunt.com/posts...
hahaha the visual is hilarious.
The product is fantastic. I was interested in this technology last year when I wanted to create an app for children on the Autism Spectrum. Super glad to have found this! Excited.
Good hunt @EAWharton !
