Hybrid QR Code

Safe without the worry of counterfeiting!

-The amount of information that can be stored is more than 10 times! (More than 100 times with sequential display of a series of codes with time!)

-Important confidential documents (approximately up to 7,000 characters in size) can be transmitted and received safely.

-It is possible to store self-photographed face photos taken with a smartphone.

-Automatic check-in can be realized in conjunction a face authentication system with registered face photos.

Description of the Hybrid QR Code

It has been found that the conventional QR code can be fabricated. In order to avert issues of the conventional QR code that originate from the public disclosure of specifications for the generation and the reading of the code, corresponding specifications of the Hybrid QR Code (patented) are not disclosed. A dedicated code reader is currently under development, and a prototype has been completed.*

The amount of data that can be stored in a Hybrid QR Code is more than 10 times that of the conventional QR code. With a Hybrid QR Code based upon the version 16 QR code, the storable amount of text data is about 7,000 in Japanese characters and 20,000 in English characters, and storable size of images is about 4.7 KB and thus face photos can be recorded. Furthermore, by using a series of codes which is sequentially displayed with time, the data size can be more than 100 times that of a conventional QR code.

Since data can be transferred without using the Internet, security is extremely high, and there is no need to pay for server installation and operation. Thus, the code can be applied for ID authentication indispensable for hotel check-ins, entry to member exclusive facilities, and fee-charged events. It is also effective for the transmission of highly confidential information.

*Currently, research and development are being carried out so that even smartphones with low resolution cameras can read the code.
