  Globalization has introduced many new challenges making Supply chain
management (SCM) complex and huge, for which improvement is needed in many
industries. The Internet of Things (IoT) has solved many problems by providing
security and traceability with a promising solution for supply chain
management. SCM is segregated into different processes, each requiring
different types of solutions. IoT devices can solve distributed system problems
by creating trustful relationships. Since the whole business industry depends
on the trust between different supply chain actors, IoT can provide this trust
by making the entire ecosystem much more secure, reliable, and traceable. This
paper will discuss how IoT technology has solved problems related to SCM in
different areas. Supply chains in different industries, from pharmaceuticals to
agriculture supply chain, have different issues and require different
solutions. We will discuss problems such as security, tracking, traceability,
and warehouse issues. All challenges faced by independent industries regarding
the supply chain and how the amalgamation of IoT with other technology will be
provided with solutions.
