According to BlockBeats, on July 11, Seattle-based Dangerous Things and VivoKey Technologies used NFC and RFID technology to launch a cryptocurrency wallet that can be implanted under the human skin to enable secure cryptocurrency transactions.

According to officials, "These wallets are hardware wallets used to send cryptocurrencies. Your mobile app is your interface, but it does not have any private keys. The private keys and the actual signing of Bitcoin transactions or encrypted transactions are all done in the chip." The implantable device Apex Flex retails for $349.

Several different Bitcoin and cryptocurrency wallets are currently supported. These include: Satochip wallet, Seedkeeper app, and Status IM keycard wallet. These wallets are for different blockchain networks.

Founded in 2013 and 2017 respectively, Dangerous Things and VivoKey specialize in near-field communication (NFC) and radio-frequency identification (RFID) technologies that are custom-installed inside the human body.
