Please help me answer the question below after my post. Thanks!

Contracts are evolving rapidly in response to new systems and technologies, which are impacting various aspects such as sustainability, quality, and the acquisition process itself. The emergence of e$-$commerce has significantly altered the landscape of contracting, particularly in terms of how products and services are sourced and procured. E$-$commerce platforms have increased the accessibility and visibility of potential suppliers and also facilitated the process of comparing offers and negotiating contracts. Additionally, the integration of Radio$-$Frequency Identification $($RFID$)$ technology has enhanced supply chain management by providing real$-$time visibility into the movement of goods, thereby streamlining inventory management and improving overall efficiency.

A good posting but is RFID necessary for real$-$time tracking? Amazon seems to always know where my stuff is but I am not sure they have RFID detectors on all their boxes. What do you think?
