More secure
‍
‍All QR codes are generated and recognized by anyone that uses them. Therefore, all of the services use the same recognition module. There are attack techniques such as Q-shing that exploit this security vulnerability to lure users into fake sites and steal personal information.
‍
Sonic Code® does not disclose the way sound waves are created and recognized by any other means. It uses a dedicated code module that only recognizable each customer's dedicated code band and uniquely corresponding that particular band. Therefore, it can be used more securely than the QR code scanning.

‍More convenient
‍
‍QR requires user action, such as turning on the camera function, moving the QR code image while looking at the camera preview screen, and waiting for focus. Sonic Code® automatically recognizes the signal by basically operating the module and moving it within the effective range of the sound wave, so no additional user action is required.

In particular, in a usage environment that transmits data between smartphones, Sonic Code® is easier to use than any QR code scanning where light reflection, screen illumination, or hand tremors interfere with the recognition of scanning code.

‍More economical
‍
‍In order to use the dynamically generated QR code, a separate display unit is required to display the generated QR code. The only device that needs Sonic Code® is the speaker, and it works without problems even for low-end speakers. If you need to build an infrastructure with an inexpensive device without a display, Sonic code® to be considered as a cost-effective and low cost of ownership compared to QR, which requires a display device.

We think Sonic Code® is not a substitute for QR codes, but rather a complementary technology to QR codes. It can be used with a QR code, and I think it will be a great alternative in an environment where QR code use is inconvenient.

Not only can Sonic Code® substitute QR codes but also be a technology that complements QR codes. It can be possible to use along with a QR code, and we believe it will be a great alternative in an environment where QR code use is inconvenient in particular.
