Card Wallet

The Card Wallet is a co-production of Coinfinity and the Austrian State Printing House, and offers a simple way to securely store Bitcoin offline in form of a tamper-proof card. The Card Wallet is manufactured in the high-security room of the Austrian State Printing House in an isolated offline system, using Coinfinity’s Secure Entropy Technology. The private key is sealed tamper-proof before the card leaves the production machine, and immediately deleted after the process so that not even the staff at the high-security room can ever see the key. High-quality security materials and tamper-proof features prevent a manipulation of the card.
