Of course, you will then need to send this key pair to a printer to create the paper wallet itself. However, we now face a new problem because the dangers of losing our coins have merely shifted from the digital world to the physical one (the printer).
Devices malfunction and other unexpected mishaps can result in your keys and/or QR codes being printed incorrectly. Thoroughly test them at each step.
These printed characters cannot and should not be assumed to have correctly transferred to the paper.
Poor ink, jammed paper, lousy printing performance or power interruptions are all likely to render the paper wallet useless.
Now your key pair is printed flawlessly.
Unfortunately, we aren't out of the woods yet.
With a paper wallet, the coins remain in danger the entire time that you leave them in that address.
Because the paper itself could be lost, stolen, observed by unwanted parties, burned, faded or sustain water damage.
You might be wondering, "Should I just put my paper wallet in a safety deposit box?"
