Electronic Stamps

There are three types of electronic stamps that we have developed and are providing: The C-Stamp, the G-Stamp, and the B-Stamp.

No Internet required! The installation of a reward point service system is easy with an electronic stamp!

A unique “Capacitance Code” is set for each C-Stamp, enabling the identification and authentication of each stamp. No power source is required. By authenticating the “Capacitance Code” which is linked to a certain store where it is used or to a location where it is installed, and linked to services, it is possible to use functions such as the issuing and erasing of reward points and coupons, applying stamps in stamp rallies, and ticket confirmation, at will.

C-Stamp Technology

For conventional electronic stamps, there is a limit in the amount of electrode arrangement patterns that can be set, and the recognition accuracy of the “Capacitance Code” has been a lingering issue. Our C-Stamp is equipped with a special mechanism that can control the ON/OFF of the current flowing between a human finger and an electrode. In addition, a unique method for controlling detection/non-detection of the electrodes by a smartphone has been developed, allowing a large number of electrode arrangement patterns to be detected without any misrecognition. In addition, forging is difficult. Therefore, by identifying and authenticating each stamp used in the tens of thousands of different locations, it is possible for each store to provide various individual services.

B-Stamp

Receiptless payments and use as electronic seals are possible! Advanced electronic stamps are put to practical use!

The B-Stamp is equipped a with Bluetooth and is of a chargeable type. Using Bluetooth communication, data communication with POS systems is possible. When you press a stamp onto your smartphone, pairing is completed on the spot, and receiptless payments can be made without using the Internet. In addition, the store side can select various services on the spot and provide them to users via Bluetooth communication. A developmental prototype has been completed, and software for various applications are currently under development and will be released next spring.

Description of How to Use a B-Stamp for a POS System

① The store clerk inputs information of the product for purchase, and the “B-Stamp” connected to a POS system receives purchasing data and temporarily stores it in the stamp.

② The customer activates the corresponding smartphone application and a window for applying the stamp is displayed.

③ When the clerk presses the stamp onto the window for applying the stamp, the smartphone receives the purchasing data temporarily stored in the stamp.

④ The purchasing data is displayed on the customer’s smartphone, and after confirming the product and the price, the customer clicks the settlement button.

 

⑤ The stamp receives the “settlement confirmation” message via Bluetooth communication from the smartphone and relays it to the POS system.

 

⑥ The POS system sends instructions to the application member server and the proxy settlement server to complete the payment.

 

⑦ A payment completion message is sent from the proxy settlement server to the POS system.

Applications

In addition to the receiptless payment system introduced above, the B-Stamp can also be used to authenticate electronic tickets for concerts and amusement facilities purchased on smartphones.

By sending a B-stamp device ID unique to each stamp, personal authentication is possible and thus the stamp can also be used as an electronic seal.

As for the capacity of a B-Stamp,

-about 5 KB of information per second can be sent or receives.

-a text of about 7,000 Japanese characters and face photos with sufficient resolution for identification purposes can be sent or received.

G-Stamp

Multiple tasks are possible with a single stamp!

Realization of data reading and transmission without using a wireless system is possible. The birth of a next generation stamp with perfect security!

The G-Stamp is a next-generation electronic stamp which reads an “Invisible Dot Code” printed on paper or displayed on a display, decodes it into a “Capacitance Code”, and sends it to a smartphone. Videos, music, or confidential data, etc. are then immediately displayed.

The Structure of a G-Stamp

By controlling the ON/OFF of the electrodes, the G-Stamp issues variable “Capacitance Codes,” and more than one million “Time Variable Series of Capacitance Codes” can be generated and controlled. This enables multitasking.

Applications of a G-Stamp

A single G-Stamp can provide multiple services. In addition, relatively large volumes of data can be transferred, and since security is high because the Internet is not used, it is safe to transmit confidential information. Educational materials or media on which a dot code is printed is touched with a G-Stamp and the dot code is read. Then by touching a smartphone or a tablet with the G-stamp, a decoded “Capacitance Code” is issued and a variety of contents such as videos and music can be enjoyed. Application to e-commerce is also possible. Furthermore, if the stamp is made to recognize the position it touches and rotation angles, new games and attractions linked to cards and boards can be realized.

*The G-Stamp has been tested successfully with iOS installed smartphones, and thus the mass-production of G-Stamps for use with iOS is possible. Currently, we are conducting further research to development G-Stamps that it can be used with other operating systems and on various devices.
