The CRS-IUA app implemented functionality using Apple’s iBeacon technology which can provide a shopper who has opted-in, promotional or other information when the shopper comes into proximity of an RFID iBeacon device. See the Apple website for specific details on the Apple iBeacon specification.

For ASA, this implementation alerts ASA when a CRS-IUA opted-in shopper enters a store and provides a method to let an associate respond to a help request from that shopper. A server side framework provides information on the beacons encountered and interprets these as unique events.
