The Ministry of Internal Affairs and Communications (MIC) of Japan revises the technical standards for the Giteki certification marking.

Sample of the Giteki marking
R Mark - Radio Equipment Technical Standard Conformity Certification
T Mark - Terminal Equipment Technical Standard Conformity Certification
The goals of the revisions are as follows:
- Relaxation of the size requirement of certification mark.
- Allowing for radio equipment without displays to indicate the mark via an external display.
Revision of Certification Rule Format 7, Format 14 Note οΌ as the following:
βNote 1 The size should be easily identifiable.β
There is no longer a minimum diameter requirement for the marking (previously 3 mm or greater).
Addition following rules to Certification Rule Article οΌ, 20, 27, 36, 41:
βAn electromagnetic method that the display can immediately display the Certification Mark based on Format No. 7 in a clear state on the display of the product connected to the specified radio equipment that meets Technical Standard Conformity by a specific operation (Given that it can be displayed by wired connection with another product with built-in display before the operation of
the specific wireless facility is first started)β
The device marking can be displayed on an external/peripheral monitor if the device has no built in display.
Due to the miniaturization and high integration of IoT devices, the indication of the mark of 3 mm on the modules etc. becomes difficult. In order to ensure the usability of IoT equipment etc., the mark should be easy to attach and recognize.
