The research division of Japanese Technology Corporation Sony announced the creation of a contactless hardware crypto-wallet . The device has not yet received the name and uses the popular smart card technology in Japan for communicating with a Bitcoin network or other cryptocurrency.
The wallet provides a high level of security due to the storage of coins offline, while also offering ease of use at the level of online services for storing cryptocurrencies .
While the usual Trezor One and Ledger Nano S hardware wallets need to be connected to a computer or mobile device using a USB cable, the Sony CSL wallet uses contactless technology. The latest development provides secure storage of private keys using a contactless IC Card, allowing users to easily confirm transactions through a mobile device that supports NFC wireless technology.
According to the staff of the Sony Computer Technologies Laboratory (SCSL), the advantage of the device is that the user does not need to connect it via a USB port.
“In addition, it is possible to securely generate and store a private key in the high-security module inside the IC card protected from hacking ,” the company explains.
In recent years, Sony has been actively involved in the life of the blockchain industry, releases its own technology-based solutions and patents scenarios for its use.
The company notes that in addition to receiving and sending cryptocurrency, its latest hardware wallet is suitable for other functions.
“The hardware crypto wallet on the IC card can not only manage private keys that are used for cryptocurrency transactions, but also manage private keys for other tasks, such as providing access to the use of personal data using blockchain technology,” Sony writes . "This is an infrastructure technology with many possible applications."
