Not sure if this has been mentioned/seen before but anyways. I recently had to cancel a Chase credit card because of fraudulent activity. This was the default card for my ApplePay. Anyway, I called Chase around midnight and cancelled it and they said they would send me a new one in the mail in a week or so. I never update or remove the card from ApplePay. The next day, I am at the drugstore and use ApplePay, works without a problem, but I see that its the card I cancelled. I ask the cashier if it went through and they said "yep, you're good". As I'm walking out of the store, I get a notification from Passbook that says "your Chase card is ready to use" which I find weird, so I check Passbook and the last 4 digits of the card have changed (at this point I don't even know what my card number is since I haven't got it in the mail, so I don't really know if this is the right card or just some glitch). I get home, log on to my Chase account and see that the last 4 digits match. So I left it be to see if the pending charge would go through (it did a few days later). I got my card in the mail today and the last 4 digits match. I'm not saying its good or bad that ApplePay autoupdates the card number. I was under the impression that each card would have to be manually added (take picture then confirm etc) but maybe it just syncs with the Chase app? Anyone had this experience before? If not, hopefully someone can shine a light on why/how it happens? I have no problems with it really, just curious about how the info was obtained without me having to take a picture of the new card.
