Paper wallet is a very secure method of storing bitcoins offline. But its main problem is storing without damages. For that, I found a solution;
If you have Printer in your home, Scan your bitcoin paper wallet as JPG image OR PDF and save it in a new folder.
Next step is convert this folder as rar OR zip file with password. Then store in your Memmory card, Pendrive, Memmory card OR personal computer. It never become damaged.
We can extract these files whenever we want. Then we can take prints if needed.
you can still burn. step on. smash with hammer.
you can hand it to a kid who can snap off the usb end from the plastic cover
lose out of your pocket. thief stealing it. connect it to a computer with a virus.
electric shock. lightning strike, car accident,
the list goes on.
..
separate note.. having a paper wallet has its own utility.. putting it on digital media or a PC is no longer paper wallet.. emphasis on the word paper
You can keep copies in multiple devices. Dont store in one device. 1 copy in your personal computer, 1 copy in Pendrive, 1 copy in Micro SD card, 1 copy in External Hard disc .. etc.. Dont connect these things with other devices and internet.
