If you stay at a Disney resort, they send you a Magic Band (which I have already shown you) that acts as your park ticket, your room key, and your FastPass (skipping long lines for rides), and if you link your credit card to it (and a PIN), you can use it to pay for EVERYTHING. (If you don’t stay at a resort, you can still buy one and use it the same way.) It was incredibly convenient, and it meant we could really pare down what we had to carry. It’s making me reconsider services like Google Wallet and Apple Pay. There are still security concerns, and I’d always have to have my phone, but I always DO have my phone. Obviously, there are still places that don’t use those services, so I couldn’t use it all the time, but I’m willing to bet it’ll become more and more common, just like it’s more and more common for even street vendors to take credit cards. It’s something I’m thinking about, anyway.
