HITCON CMT 2018 HITCON Wallet Badge
Blockchain wallet badge with secure element, e-paper, Wi-Fi, and BLE
HITCON CMT 2018's official events page documents HITCON Wallet as a limited blockchain electronic badge for Royal VIP and Premium Pass holders, with secure-element cold-wallet functionality, electronic paper, Wi-Fi, and Bluetooth Low Energy. The same official page says holders could join a secret activity during the conference and later use the device as an offline physical wallet for Bitcoin or Ethereum.
