These paper wallet were fun, but scary to use, as you could easily fuck up with change and other thing while trying to get the btc out of it.

Now I still have Lightning vouchers with the same idea, but I can always redeem them if they get lost or never used by the receiver. But use case is similar.

And to be honest most people use a simple piece of paper to write their backup seed, so technically a lot are still havinh their wallet on pieces of paper.
