Snaptell I haven't seen this covered in the ecommerce World, but it is in the startup press. Earlier this week, Amazon (AMZN) acquired the startup Snaptell. Snaptell had a free app for the iPhone and Android that allowed you to take a picture of a random product, have it identified and then price shopped online.

The amount of the acquisition wasn't disclosed, but snaptell had raised $4m so I suspect the valuation was at least 2x that if not more.

Amazon already has a great mobile app with a similar 'remember' feature. In a WSJ piece, an Amazon spokesperson said:

Amazon will continue to "work in innovations in search technologies and enabling visual shopping on a range of mobile devices and platforms," said a company spokeswoman. "It's very early days for image recognition based search technology and we believe there is a lot of innovation in visual product search ahead of us."
