Placecast's ShopAlerts service powered by LOC-AID is a retailer marketing solution. Retailers leverage the technology to create their own version of the service; then consumers choose the brands they love, and may opt-in through many ways - at the store, online, via text-message, mobile website, or social network (like Facebook). Once ShopAlerts is activated, consumers go about their day and the service automatically alerts them when they are near a location that they are interested in or when the brand is offering sales and specials.
