There's a smartphone app called dscout that allows you to get paid for "missions". Basically completing tasks on your smartphone (mostly taking pictures and answering questions).
dscout is leading a very special set of missions designed to help bring
classrooms into the digital age.
If selected, you will receive $150 to complete 3 brief missions using your smartphone for ~1 hour of work in the next few days. (TEACHERS ONLY). I'm sure a lot of teachers can use the extra cash!
