 The race to replace your wallet is officially on. It started a few years ago with Google Wallet and more recently Apple Pay, but there's been other independent players like Plastic and Coin taking a tangible approach with a single programmable card. After months of delays, I finally got my CoinBeta in the mail. It looks and feels just like a regular credit card, but it has an e-ink display and a button. Setting up Coin involves a smartphone, the Coin app, and their included card reader. The process was a bit confusing at first. In order to buy something with Coin, you have to first pair your coin with your phone, then add various credit cards and debit cards, and then sync coin with your device to get your cards over. There are a few other hoops you have to jump through, like entering your CVV and verifying your card, but once you understand how to sync one credit card, the process makes sense. And once you've got the cards synced, you just press the button to cycle through them. We set out to do three real world tests with Coin. First, buying something at a drug store. As expected, Coin worked without a hitch at a normal point of sale machine. Next, I went to get lunch. So we're here inside Crisp where I frequently eat lunch, and Crisp has a membership card which I've got programmed into my coin. And what's neat is you can actually nickname your membership card. So I've got the Crisp card here, and I've got my credit card here, so let's get some lunch. The cashier at Crisp thought Coin was really cool, but I could see how it would be confusing to some people who are used to seeing a specific membership card. Boom. Went through? Yes. Yes. Awesome. And for our last test, I'm at an ATM machine right now, and ATM machines sound like they eat your cards, and I have no idea what's about to happen if I try and take out money with the coin, but let's see what happens. All right, should I... Let me know when you're... It's literally not reading it. Doesn't want to eat this at all. Try a different machine. Wells Fargo does not like the coin. So coin works as well as you'd expect it to. Anywhere that takes credit cards takes coin. But my shopping story was cut short because it didn't work at the ATM machine. Let's go eat. It almost equaled closed.
