I notice it's also labeled as displaying ads. And this is Amazon's debut offering. It's not going to get better from here as they get more adoption. I do not want this app on my phone. Everything I know about about the mobile ecosystem tells me that if an app/card/integration is required for an unrelated service, it's going to go downhill over time. Everything I know about Amazon means that they are definitely going…
They require a special credit card? I connected my usual credit card from my bank to the account half a year ago and have been using it successfully with Apple Wallet just fine.
Regardless, even linking my own cards, this is still kind of a crazy concept, isn't it? It's still strictly worse on nearly every single axis than a normal charge/gas station, where I can still just as easily pay with platforms like Apple/Google Wallet, but also with a spare twenty if I've left my phone at home or if I'm loaning my car to someone else.
It's very difficult to come up with a business model that says, "you must only pay us or interact with us in a special, tracker-friendly way" that isn't going to eventually become profitable by selling a lot of data or targeting you with ads. There are some exceptions to this rule, but they are very few and far between, and Amazon (and I suspect ChargePoint as well) are not among them.
In fact, you can already look at ChargePoint's privacy policy[1] and see that they're carving out terms that allow them to share your personal/location/purchase data with affiliates and partners, as well as to use your information to deliver tailored ads.
