Most of the time i dump flyers in the nearest trashcan, i think more people do.
The QR code should be scanned with the app, and funds deducted from a centralized wallet at that point i guess, if you pre-fund the paper wallets, a lot of funds will go lost.
That's why you sell the idea before you give them the paper wallet. You present it as giving someone cash... people don't throw cash away. Maybe team with the Subways that accept it and do a little info stand to explain it to people. A big sign saying ask me about NLG and how you can get some for free. Tell them that just by learning about how to set up the wallet on their phone, you'll fund the wallet for a discount on their sandwich purchase.
IDK... I just wish I lived in the Netherlands now lol.
