There are various classes of ucodes. Are frequency bands and communication protocols in each class different?
Basically, more than one type of frequency band and communication protocol are used for ucode tags. However, this does not mean that any kind of frequency band or communication protocols can be used. Ucode tags are authorized in accordance with the standards set by the following policy. First of all, it is a given fact that the frequency bands and intensities of radio waves used for communications meet the legal restrictions in the areas where the tags are used. It would not be a problem if various different types of communication protocols were used. However, from the perspective of user-friendliness, situations in which users have to be aware of different communication protocols for tags used in the world and change their read/write devices accordingly should be avoided. Therefore, it is important that data can be read using a single ucode tag read/write device, such as a Ubiquitous Communicator (UC). If that is technically possible, we believe that it will not be much of a problem t
