It's big news today that Walmart is expanding their i-phone app check out services to more stores in the US.  ( None in Maine yet ) And I was thinking in my jaded, pragmatic way..."what is to stop the unscrupulous from taking advantage?"  Here is what they have in place. First, you have to register to use the service and then agree to this...

" This Application may permit customers to scan products at Walmart stores with their mobile devices and use mobile checkout solutions (“Mobile Checkout Services”), including without limitation Scan & Go. By using any Mobile Checkout Services on this Application, you agree to accurately scan all products before checkout and pay for all products you obtain from any Walmart store. "
