Supply Chain Protection

Getting an uncompromised product into your hands

Bag number

First and foremost, we use a tamper-evident plastic bag to package the product. Each bag is unique and coded with a number.

Epoxy globs of love

We cover the secure element, and other sensitive parts of the Coldcard with epoxy.

Clear case

The clear plastic case on Coldcard is an important feature as well.
