What is a private key?
The private key serves as a proof of ownership to the network. The private key signs transactions which then are validated by the network. Without the possession of the private key, access is not possible.
What is the private key made of?

Is the private key saved?
The private key printed on the back of the card exists exclusively on the respective Card Wallet, there is no copy of the private key. The generated key never leaves the production machine, and can not be viewed by employees at any time.
