I understand that Google is now working on POS systems, kinda like a cash register, but instead, it’s a gas pump and instead of money, information is pouring out of the pump, according to Bill Sobel at ny:mieg in Filler Up with Google

The Google Gas Pump information system (not kidding – though I don’t know what it’s actually called) uses Gilbarco’s new Applause media system that serves Google’s local search, maps and local listings, driving directions, coupons and more.
Maybe the next stop is Restaurants (assuming we’d be able to search on the information on all the foods we’re being served while looking at local advertising) – I guess if that happens, we’ll also be able to use the search engine in exchange for giving our attention.
