I need an example of "cost saving estimation" when implementing RFID system in a Store or Warehouses implementing Barcode system for the same store. please give examples by providing numbers (number of items in the store, cost of labor, number of hang tags, prices of hang tags and barcode, cost of devices for each system..etc) and compare the numbers by proving why RFID is more cost saving than the barcode.

Please refer to the attached picture. And provide your information references.
