Cosmetics company Sephora is rolling out a Bluetooth Low Energy (BLE) beacon solution to provide content related to a shopper's proximity when that customer uses Sephora's app on an Apple iPhone. The beacon system is slated to be rolled out to all of the company's stores following a pilot of the solution that began in the fall at two San Francisco-area sites. The retailer has not indicated the timeline for the installation rollout. The beacons and content-management software are being provided by Gimbal.
