1.Various industrial sectors including retail, transit systems, enterprises, educational institutions, event organizing, finance, travel etc. have now started leveraging these beacons solutions to track and communicate with their customers.
2.A beacon fixed on to a shop wall enables the retailer to assess the proximity of the customer, and come up with a much targeted or personalized communication like offers, discounts and combos on products in each shelf.
3.Smart phones or other mobile devices can capture the beacon signals, and distance can be estimated by measuring received signal strength.
4.Beacons are tiny and inexpensive, micro-location-based technology devices that can send radio frequency signals and notify nearby Bluetooth devices of their presence and transmit information.

Explanatory Answer

4 introduces beacons and is the best starting sentence. 43 is a link: 4 states that beacons send radio frequency signals; 3 explains that smart phones and other mobile devices capture these signals. 12 is also a link: 1 says that several industrial sectors have begun to use beacons to track and communicate with their customers; 2 explains how these beacons are actually put to use to track this information. 4312 is hence the correct order.

The answer is '4312'
