Highly damage resistant Cryo Cards

American company CryoBit focuses on producing Cryo Cards cold storage that is highly resilient to damage.

This week CryoBit published a video showing a saltwater corrosion resistance test and a detailed description on what happened to the card after 10 days (album of the Cryo Card prototype after 10 days).

“So far the card it is performing as expected. The type of stainless steel used in Cryo Card’s construction is marine grade, meaning it has superior corrosion resistance to water, especially warm saltwater,” wrote company representatives to /r/Bitcoin. “We will continue to post updates on Cryo Card's superior corrosion, heat, and scratch resistance on a weekly basis.”

The test is a continuation of previous tests, including an impressive high temperature propane torch test.

Coin Telegraph has already examined some of the more damage resistant offline wallets before but this time we can see demonstrations of how actually damage proof cold storages can be.

According to legend, the CryoBit company was founded by two crypto-currency enthusiasts - Brian Atchley and Cody Maher, who decided to search for a better solution of offline paper storages after one of them (who will remain unnamed) lost a paper wallet in a minor flooding incident.

The problem of how to ensure that their personal coins could be kept safe from the wet, humid, and corrosion inducing climate of their home state of Florida was the first step.

Today CryoBit company produces Cryo Cards both for Bitcoin and Litecoin .

The base layer of Cryo Cards is made of AMS 5524 stainless steel, which is aerospace grade metal that demonstrates high level of resistance to both high heat temperatures of up to 2500°F (1370°C) and corrosion in all environments (resistant to acids and bases, fresh and salt water).

Inscriptions are made by a high-contrast proprietary ceramic-glass material that exceeds the metal’s oxidative and thermal performance. It makes cards surface virtually scratchproof. Moreover, it seems to be almost impossible to erase original markings of the card without removing the metal layer underneath.

To generate private keys improved AES- 256 encryption is used. The process of generating keys for Cryo card is performed in your own browser and not on the servers of the company, so no one except you will know your private key.

The Cryo Card prices are about US$20-$30.  All cards are shipped by USPS first-class for all domestic US orders, while international shipping is also available at an additional charge.
