ucodes are one of the central technologies of ubiquitous ID technology. ucode is a unique ID used to identify physical objects, and the device in which the ucodes are provided is the ucode tag. In Ubiquitous ID Center, because the usage and characteristics, etc. are different, bar codes, RFID's, smart cards, and active chips, etc. are comprehensively handled as ucode tags. In Ubiquitous ID Center, the certification criteria for these standard ID tags are set for each interface category, and tags that satisfy these criteria are certified as standard ID tags.
The basic policy for authorization is, 1. To provide method that enables the acquisition of ucodes 2. To guarantee the uniqueness of ucodes, 3. To be able to distinguish between ucode tags and non-ucode tags, 4. To clearly display ucode tags. As ucode tags.
