ucode is an ID to identify various types of objects and concepts. This ID is a number and has no meaning in itself.
The objects that can be identified by ucode, for instance, are fruits such as an apple and an orange, a home appliance, each component of a home appliance, and an abstract concept such as the distribution record of these items. This makes it possible to track the production area and nutritional information of foodstuff, its current location, status, history, etc. In this way, ucode can identify an “object” and “concept” anytime, anywhere.

ucode is assigned to an “object” to identify it, and the device that stores ucode is called a “ucode tag.” There are many types of “ucode tags” such as barcodes, smart IC cards, and active/passive RFID chips. One of the features of ucode is that the types of tags for ucode are not restricted to a specific physical tag. An application system can be created by selecting a type of ID tag that meets the budget, necessary functions, and performance of the application.
Examples: barcodes, 2D barcodes, color codes, passive tags, active tags, sensor network nodes, etc.

An “object” is not limited to movable objects but can be immovables such as buildings and “concept” such as location.

YRP Ubiquitous Networking Laboratory has developed the ucode and its operation method. ucode is globally acclaimed as an ID system that became the basis of International Telecommunication Union Telecommunication Standardization Sector (ITU-T) Recommendations (i.e., standards).

UC Technology has applied ucode from an early stage to build IoT applications to contribute to safety and efficiency in everyday living, the public infrastructure, and the industry sectors in Japan and overseas.

The technical specification documents of ucode are available on the website of uID Center.
