Thanks, guys.
What about this bit here?
Apple decrypts the data, determines your card’s payment network, and re-encrypts the data with a key that only your payment network (or any providers authorized by your card issuer for provisioning and token services) can unlock. Then it sends the encrypted data, along with other information about your iTunes and App Store account activity (such as whether you have a long history of transactions within iTunes), information about your device (such as phone number, name, and model of your device, plus any companion iOS device necessary to set up Apple Pay), information about your device usage (such as percent of time device is in motion), as well as your location at the time that you add your credit, debit, or prepaid card (if you have Location Services enabled) to your bank.
By enabling Apple Pay, I'm giving Apple permission to send my list of downloaded apps and media to my bank along with basically every identifying bit of info about my iPhone, just for the privilege of using my credit card in a different way? Is that really necessary???
I thought Apple gave a damn about users' privacy.
