How it works | Bitbills

Security

Security is a crucial component of Bitbills. There are two key aspects to card security: anti-counterfeiting and tamper-evidence.

We use industry-grade production techniques and special security holograms to make Bitbills nearly impossible to counterfeit. It's important that when a stranger hands you a Bitbill, you can be sure that it was made by us.

It's also important that it is clearly evident when a card's private key has been accessed. By embedding the key inside the card between two secure holograms, the only way to access it is by visibly destroying the card. Following thorough x-ray testing using a wide range of energies, we have determined that private keys cannot be resolved via x-rays.

Whenever handling a Bitbill, always be sure to check that the design matches the one shown on this website, and that both the front globe hologram and reverse "Secure" and "Valid" hologram are intact. Do not accept a Bitbill if it's damaged, shows signs of tampering, or looks unusual.

We are constantly working to ensure that Bitbills remain the safest way to store and trade bitcoins. If you have any questions, comments, or concerns about their security, please email us at security@bitbills.com.
