When RFID is applied during the supply chain process, it can reduce staff checking time for inbound goods by up to a massive 80%, and continual inventory checks of what is on the shop-floor and in the store is also improved, meaning it can be done more frequently, or with fixed infrastructure can be in real-time. Brand authenticity is a serious issue for retailers, with the need to gurantee genuinity paramount to shoppers. With high-levels of encryption, and the ability to integrate into products, RFID can be discreetly used effectively as an authentication aid.
