In the retail industry, the blockchain technology could have diverse applications. For once, it offers a tool to gain consumer trust. Tracking products from source to point-of-sale on an immutable ledger in a time where consumers grow more and more wary of the origin of products can prove a valuable asset. Additionally, it can eradicate the danger of counterfeit goods, which is especially relevant for high-value items. It also offers a more versatile payment option. Payments via blockchain, such as Bitcoin, cost fewer fees than current cash-free options. They also offer the added benefit of integrating reward schemes and fraud-proof gift cards into the payment process. Furthermore, by combining blockchain with Internet of Things technologies, retailers can automate processes (i.e. automatic ordering from smart shelves through smart contracts) and generate new revenue streams through automated orders by smart devices.
