If RFID has been around so long and is so great, why aren t all companies using it?
Many companies have invested in RFID systems to get the advantages they offer. These investments are usually made in closed-loop systems that is, when a company is tracking goods that never leave its own control. That s because all existing RFID systems use proprietary technology, which means that if company A puts an RFID tag on a product, it can t be read by Company B unless they both use the same RFID system from the same vendor. But most companies don t have closed-loop systems, and many of the benefits of tracking items come from tracking them as they move from one company to another and even one country to another.
