If holiday shopping has left your wallet feeling a little lighter than you'd like, why not cash in some on your old phone? Rather than heading to eBay or Craigslist, you can actually head back to the mall and find your nearest ecoATM.

The ecoATM is an automated kiosk that evaluates and then purchases your used consumer electronics right then and there—for cash.

All you have to do is plug your device into the testing station. The machine does all the work, evaluating whether or not the device works, and then evaluating the very best price for it. Your old device doesn't even have to work; the company sells the obsolete pieces to companies that recycle them for parts and the tiny amounts of precious metals in every phone.

If you agree to the price, the machine pays you cash right then and there for your electronics. The machines use patented "machine vision," electronic diagnostics, and artificial intelligence to evaluate and buy-back used cell phones and MP3 players making them certainly the coolest way to recycle your old e-waste. Plus, the company claims that they pay more money for more types of phones than anyone else.

Your used smartphone could net you up to $250 in good condition, but even a few bucks are better than nothing for an old, broken phone; plus, you'll get the warm fuzzy feelings, knowing you're recycling your phone instead of sending it to landfill purgatory.
