The pri­vate key is a ran­dom 256-bit num­ber. This is long set of num­bers, and the ran­dom selec­tion ensures that the same pri­vate key is not gen­er­at­ed twice. But it is very impor­tant that the ran­dom num­ber gen­er­a­tor actu­al­ly gen­er­ates ran­dom num­bers and not just pseu­do-ran­dom num­bers.

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.
