Technical FAQ

Can't you really hear Sonic Code®?

It is generally known that humans can hear between 20Hz and 20KHz, and dogs, up to 21.1KHz. Most adults are unable to recognize the frequency range of Sonic Code® but may be faint for small children, pets, and people who are very sensitive to hearing.

Is Sonic Code® harmful to humans or animals?

For us, the user-health is always principal consideration. According to a paper jointly researched by Showa University Medical School of Yamaha in Japan, sound waves below 20KHz are harmless to humans and animals. Infosonic designed Sonic Code® to transmit only a short distance of about 30cm at weak energy compared to competitors and recommends that customers use it at a sufficiently low volume for a short time through the documents provided at the time of sale.

Can you trust the technology applied to Sonic Code®?

None of the technologies or algorithms used in Sonic Code® are entirely new. These are already well-established in academia and industry, such as ‘discrete structures’, ‘information theory’, ‘digital signal processing’, and ‘artificial intelligence’. We have been working for a long time to create the products we want by combining existing theories and technologies. Sonic Code® of today is a product that we have continually improved by repeating the process of designing, manufacturing, and testing, based on existing theories and technologies.

What happens if another device at a close distance recognizes the Sonic Code® signal first?

Since the sound wave signal has broadcasting characteristics, it can receive by any device at a valid distance. If a device with two identical recognition modules at an effective distance activates the app at the same time and be able to receive it, a situation may occur in which the unwanted device recognizes first. For customers who do not want this situation, we recommend two things as following:

* First, Sonic Code® must be used as a one-time token key for transaction request data.
* Second, adjust the volume of the transmitting device to regulate the use distance short enough.

Is there any problem with recognizing the sound waves even in a noisy environment?

Generally speaking, noise refers to a situation in which the energy in the audible frequency range gets strong. This frequency range is very far from the frequency range of Sonic Code® use, so there is almost no frequency interference problem. Therefore, there is no problem in recognizing the Sonic Code®.

Rather than the everyday noise environment, there may be a problem of recognizing the sound waves in special situations where a strong energy signal transmits continuously in a high-frequency band. Currently, in Japan, a service that outputs high-frequency signals over 20KHz is used to prevent harmful vermin from entering the restaurant at night.

As a result of our investigation, it confirmed that the Sonic Code® was not recognized where the high frequency of the corresponding frequency band measured at the power level above the 40 dB range.

However, if the public is exposed to a substantial amount of powerful energy in the high-frequency band for a brief period in such a place, the general people may feel a great deal of discomfort and nausea. Therefore, it is possible to say that many people rarely use such harmful vermin control services in a general place.

In other words, in the everyday environment where Sonic Code® used, it is also possible to say that the control of vermin service frequency may not interfere with Sonic Code® service.

Can Sonic Code® recognize and use normally even in the same place as other services that use sound wave signals?

At the Starbucks stores in South Korea, the sonic beacon service named Siren Order is in service. It applied to an environment in which an audible sound wave signal continuously emitted from the same frequency range through a speaker of high power. Sonic Code® has conducted signal recognition as well as signal detection tests at several Starbucks stores in Korea more than 10,000 times, and all have worked flawlessly.

Is it possible to output and play the Sonic Code® with a buzzer or piezoelectric speaker?

A piezoelectric speaker or buzzer is a type of speaker that uses the piezoelectric effect for generating sound. Most sound waves communication, including Sonic Code®, transmits data using an inaudible frequency band of 16,000 to 20,000 Hz.  

With a buzzer, the sound wave communication technology such as Sonic Code®, cannot be used. Most sound wave communication, including Sonic Code®, transmits data using an inaudible frequency band of 16,000 to 20,000 Hz.

Generally, the playback frequency band of the average speaker is 20 to 20,000 Hz. Therefore, Sonic Code® can be usable. However, since the 'buzzer' or piezoelectric speaker cannot faithfully reproduce analog signals in the range of 16,000 to 20,000 Hz frequency band, therefore it is unable or not suitable to use as a sound wave transmitting device for Sonic Code®.

What are the advantages of Sonic Code® over QR code scanning?

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.
