Recently, AI assistant is implemented and services that interact with users through text or voice are being actively tried around the world. Representative examples of these include artificial intelligence (AI) speakers and smart home services.

For example, attempts have been made to use a smart device as a digital assistant starting with Apple Siri, which is a method of linking notifications, weather, stock information, messages, etc. built into the smart device with the AI assistant function. It was. There have also been attempts to combine AI assistant functions with standalone speaker units, examples of which include Google Assistant and Amazon Alexa. Line Friends and Kakao Mini are representative examples. In addition, attempts to control home lighting by voice or to strengthen home security by linking the artificial intelligence assistant function with the Internet of Things (IoT) were attempted mainly by telecommunication service companies.

In order to properly implement such an AI assistant function, high-level situational awareness needs to be implemented beyond the conventional man-machine interaction methods 'answer questions' and 'follow commands'. In other words, even if there is no explicit question or command from the user, a method of preemptively providing service by watching, hearing, and thinking about the user's situation is required. For example, after an AI assistant observes a user based on video and audio, a user interaction such as "You are cooking. Turn on the hood now to get rid of fine dust and toxic gases. Shall I turn on the hood?" may include providing

Meanwhile, interest in cryptocurrency is growing recently. Since Satoshi Nakamoto developed bitcoin and released the source code in January 2009, more than 1,000 similar cryptocurrencies have been developed and traded. These cryptocurrencies are in the form of electronic data online that do not have a physical form (eg, banknotes, coins), and transactions are generally made through blockchain operation and transaction records are managed. This cryptocurrency account is called an electronic wallet, and each electronic wallet is assigned a unique number of about 30 characters that combines numbers, lowercase English alphabets, and uppercase letters to perform transactions based on public key cryptography (PKI).

These cryptocurrencies are expected to become effective payment methods and investment methods in the future. Currently, cryptocurrency transactions are being made through coin exchanges such as Korbit, Bithumb, and Coinone. In order to become a practical payment method, a more easily accessible transaction medium is required.

Also, conventionally, kiosk devices have been installed for various purposes. A kiosk device is a device that electronically handles tasks previously performed by humans. For example, it issues civil documents, unattended book return, or provides information services at tourist destinations. In order to perform these functions, the kiosk device is generally equipped with computation and data processing functions as a computer, and the user interaction function and network interworking function are reinforced.

Considering that such a kiosk device is widely distributed and installed to replace the role of a person, we present a technology that can use these kiosk devices well, especially in the field of cryptocurrency payment.
