Optical data exchange functionality for ease of use

Although optical, wireless and wired communications methods each possess particular strengths, infrared communications is considered the most advantageous and can be easily installed.
Laws and Regulations
The communication method is optical, therefore no regulations exist, such as the Radio Law in Japan.
Safety
Ensures worry free operation in public places, including hospitals and airports.
Confidentiality
The high degree of directivity makes it possible to specify the party you are communicating with.
Versatility
The use of mobile phones and other devices have become widespread, making the units easy to use.
Simplicity
There is no need for connectors or external cords, so data can be transmitted easily.
