I do worry a little. Every bill is a tiny museum, with its own colors, watermarks, and the way the paper feels in your fingers. When you swipe a card, you lose that texture and the story that sits between the threads. It’s not just about numbers, it’s about a tangible link to our past. If we abandon the paper entirely, we’ll be losing that quiet conversation with history. Perhaps we should keep a few originals as a keepsake, even if most of us transact online.
