There are many different ways RFID has been implemented in the present world. Some current applications to RFID technologies include: Supply chain management, Identification, traveling and livestock tracking. For supply chain management, its objective is to increase long term performance of individual companies by maximizing customer value and minimizing costs. Not all companies achieve these goals with the same strategy, but companies like Wal-Mart and Dell use RFID technologies to enhance data collection processes along their supply chain. EPC Global is the standards body that sets the standards for how basic product information is encoded in RFID chips. They developed a universal unique identification number called EPC (electronic product code) to put into every individual items RFID tag. This provides an enhanced supply chain control by pin pointing an item's location with almost one hundred percent accuracy, security, and authenticity. It also enhances customer service with faster check outs, returns, and personalization of service. Wal-Mart is a company who has benefited by using RFID in their supply chain to reduce labor costs, simplified business processes, and the reduced inventory inaccuracies.
While many business and customers are happy with RFID technology, some people feel insecure about the federal government's legislation mandating it to certain identification systems. On Aug. 14, 2006, the Department of State began issuing electronic passports, or e-passports. Prompted by recent terrorist attacks, the Department of Homeland Security proposed the e-passport as a security measure for air travel safety, border security and more efficient customs procedures at airports. Some of the e-passports security features include: a chip identification number, digital signature and photograph that acts as a biometric identifier. This also makes the passport extremely difficult to forge. But there have been many concerns raised about the e-passport's potential for identity theft. With RFID imbedded, personal information could be leaked out without the e-passport holder's knowledge. Two ways this can happen:
