Protect your Bitcoin backups against undetected access and hidden tampering.

Why use a Tamper-evident security bag?

Is your Bitcoin backup safe? You might have stored it in a safe place, but how do you know that it has not been compromised?

Creating a backup of a cryptocurrency wallet is very important, but anyone who gains access to it can take possession of all the coins in your wallet. This does not even need to happen right away, it's possible to remotely move your funds months after someone made a copy of your backup, without physical access to your wallet.

Our Tamper-evident bags erase any doubt whether your Bitcoin backup has been accessed or not:

Detect tampering at a glance

Our tamper-evident security bags are very robust, but the key element is the security tape that allows to securely seal the bag with its content.

The security tape contains unique features so that you can quickly detect any attempt of opening the tamper-evident bag.

Mechanical

The security foil is destroyed on mechanical manipulation

Steam and moisture

The water-soluble ink smears and is wiped off when exposed to moisture

Heat

Attempts of melting the glue will change the color of the security tape

Freezing

Any attempt to freeze and break the seal will discolor the security tape

Solvent

Dissolving the glue wipes off the security print and discolors the tape

Proper usage is easy

Label the bag with a pen and then put all your confidential items inside. Remove the protective sheet that covers the adhesive and carefully close the security seal.
