I've worked in wholesale logistics (backend for inventory management) for many years way back when and let me tell you, cost of ink vs cost of a chip the least of the problems. Barcodes (and QR codes as used here) have two major flaws: reading them is challenging (works fine if the package is undamaged and you TRUST that it contains what it says on the box) and they're still just a number. RFID can help with both these issues and the savings from that can outweigh the additional cost by a lot.

Utility is key and RFID has a lot of advantages over bar codes (and QR codes).
