In a privacy experiment, we bought one banana with the new Apple Card — and another with the Amazon Prime Rewards Visa from Chase. Here’s who tracked, mined and shared our data.
You might think my 29-cent swipe at Target would be just between me and my bank. Heavens, no. My banana generated data that’s probably worth more than the banana itself. It ended up with marketers, Target, Amazon, Google and hedge funds, to name a few.
Oh, the places a banana will go in the sprawling card-data economy. Despite a federal privacy law covering cards, I found that six types of businesses could mine and share elements of my purchase, multiplied untold times by other companies they might have passed it to. Credit cards are a spy in your wallet — and it’s time that we add privacy, alongside rewards and rates, to how we evaluate them.

Apple, branching out from gadgets, just began offering a needed alternative. The new Apple Card’s best attribute is privacy (though the fashion faux pas of its white titanium has gotten more attention). Apple restrains bank partner Goldman Sachs from selling or sharing your data with marketers. But the Apple Card, which runs on the Mastercard network, doesn’t introduce much new technology to protect you from a lot of other hands grabbing at the till.
With my banana test — two bananas, one purchased with the popular Chase Amazon Prime Rewards Visa and the other with Apple’s Mastercard — I hoped to uncover the secret life of my credit card data. But in this murky industry, I was only partly successful. Unlike my other recent technology experiments, such as watching what my iPhone does while I sleep, I couldn’t hack into my cards to follow the data.
