I don’t see cash disappearing either, and there really isn’t any major push to eliminate it outright. A lot of people get caught up in the digital‑currency conversation, but that’s a totally different issue from whether you can still hand someone a $20 bill for coffee or buy something second‑hand with cash.
What is changing is how often people actually carry cash and how many small businesses want to deal with it. Digital wallets are incredibly convenient, and they’re also a lot harder to steal than a physical wallet. On the business side, especially for small shops, cash comes with headaches; counterfeit bills, counting errors, theft (both external and internal), and the time/risk it takes to manage it. Digital payments cut most of that out.
So no, I don’t think cash is going away. But I do think we’ll see more situations where the local food truck, pop‑up vendor, or tiny shop just isn’t set up for cash anymore because it’s simpler and safer for them to go all‑digital.
