Followings are the frequent inquiries. If you have any questions, please contact us from the inquiry form.

Q. Is it possible to communicate even if you put it in a pocket or a bag?

A. No. You can’t communicate.

With intuitive and easy operation which securely reflects the intention of users, our design puts values the concept from “Disable communication when must not” as well as “Able to communicate when you want to”.
“Able to communicate even with a distance” can be addressed by conventional wireless communication (Bluetooth or Wi-Fi, etc.). Our design makes it disable to communicate with the leave more than a few millimeters from the body. This function prevents the unintended communication occurs.

Q. Does electric field antenna need to touch the skin directly?

A. No. it doesn’t.

Signals transmit with capacitive coupling, which capacitor is formed between communication device and a human body. Since the electric field signal is rapidly attenuated away from the human body, it has better to be placed as close as possible for more stable communication. If there is a dielectric between them, it is possible to transmit a signal along it. With the antenna embedded inside of the band, and let the surface of the band adhere to skin, or with the electric field antenna embedded in the floor, and tread it across the sole, we can communicate.

Q. Does it have any effects on the body?

A. No. t’s supposed to be not.

According to the safety standards (electric wave defense guideline) from Ministry of Internal Affairs and Communications, thermic effect (SAR: Specific Absorption Rate) is mainly pointed out in the frequency band (13.56MHz) of the NFC. Compared with the tolerance value of the SAR (2W/kg as an average of 6 minutes (4W/kg for the limbs)), small transmission output of the NFC reader and communication to terminate in a short time are considered not to influence on the human body.

Q. Data gets accessed without notice at the timing of a body touched would be a trouble. How would you address it?

A. A new mechanism to prevent unintended communication has been introduced.

As the issue of intuitive communication with those touched through the human body, the so-called “human body communication technology”, a possibility that the data gets read unintentionally by a person approaching in a crowded train, etc. has been pointed out. Not allowing communication with touching everywhere in the body, but controlling/limiting the parts of the body able to communicate, this dedicated method will prevent an unintended communication.

Q. How much are the frequency band and the transmission rate?

A. Frequency band is 13.56MHz. Transmission rate is 212kbps or 424kbps, etc.

What we provide is the technology which alters the path of communication signal. The communication itself is performed with existing IC chip and communication module, therefore carrier frequency, modulation method, communication speed, etc. depend on the specification of a chip to be used.
In other words, eNFC does not stipulate the communication method, you can freely choose and use a standard in accordance with your purpose (FeliCa, TypeA, TypeB, ISO15693, etc.).

Q. When will it be practically applied?

A. We aim for the practical application until the end of 2017.

Use requires not the “communication technology” but a new service and useful app that are realized with it. In order to implement the service sooner, we have been developing in collaboration with partners outside the company.
