A novel 'helping-cart' for assisting store customers is disclosed. The 'helping-cart' is mobile, and carries hardware for dispensing useful information such as product location inside store, detailed product information, etc. The 'helping-cart' could also be used to establish a communication link between a customer and a store attendant. Since such a 'helping-cart' with the hardware is a valuable asset, there would be attempts to smuggle the 'helping-cart' out of the store, especially because it is mobile. An independent data center may provide product information to stores. Various means to deter such potential attempts are presented.
