“Cash For High-Tech Trash”

Katie Fehrenbacher explains the concept behind ecoATMs:

You drop off old electronics at one of these machines; it calculates their value, then pays you on the spot, in cash or coupons. The company says its secret sauce is the kiosks’ ability to automatically estimate — using electronic and visual techniques — a price of the unwanted items that will give consumers an immediate financial incentive to recycle 
at the station.
