Swarm's platform integrates with store's Wifi networks in order to monitor what exactly customers are doing while shopping. In exchange for collecting analytics, shoppers get access to free internet. Swarm then send reports to the store owners, detailing how many customers checked prices online, or compared rival products on their phones. Their platform also allows stores to directly send discount codes or coupons to shopper's phones."
