This document discusses how the Internet of Things (IoT) is changing omnichannel retail. Omnichannel retail allows customers to shop seamlessly across devices and channels. The main challenges for retailers are keeping up with technology changes, providing consistency across channels, and managing big data from various sources. IoT generates even more customer data through connected devices that can be used to optimize inventory, improve product placement and targeting, and enhance the customer experience. While big data raises privacy and usability issues, retailers that establish the right infrastructure and develop a data-driven culture can reduce costs, make processes more efficient and gain insights into customer needs.
