Are there accepted and established RFID Standards?
There are international standards for specific applications, such as for payment systems and for contact-less smart cards (ISO 14443 and ISO 15693), which require encryption to keep data secure. The International Organization for Standardization (ISO) is also working on standards for tracking goods in the supply chain using high-frequency tags (ISO 18000-3) and ultra-high frequency tags (ISO 18000-6).
