Includes 3 NFC White Cards

White cards are perfect for anyone who doesn't want any design or logo. You can always assign an alias to each card to identify them without problems without having to make any type of physical mark on them, which increases security. 

You can clone copies of the cryptogram of your seeds at the lowest cost in the market with no limits, with a memory lifespan of up to 10 years. 

Our NFC cards are built with the best current technology and for thousands of usage cycles. They are designed and constructed for much more intensive use than you will give them with Cuvex.​

You will never have to update the firmware.

Completely eliminating one of the common weak points in any hardware. For this reason, it does not require any hardware components or software processes that enable external connections. 

Your Cuvex Little device will remain perpetually and completely isolated from everything. 

To achieve this, the STM microprocessors are factory-installed with level 2 protection, rendering all development and communication ports completely unusable. 

Cuvex Little is a military-grade security bunker designed to create cryptograms and store them on NFC cards. ​
