    Live in London? Use a TfL contactless reader and the transaction details in the Chase app will show the physical card number.

    Could also use an app (like Credit Card Reader) + an NFC-enabled phone. You'll need to enter the first 4 digits of the card number (hint: it's 5167).
    I've got the physical card number. Its the CVV I need 
    OK I'll bite.

    Why?
    So I can obtain my travel history from a bus company website where I've been using my Chase Card for contactless tap-on-tap-off travel 
    Interesting, I never knew they were different, and reading into the chase FAQs it sounds like its done for security reasons. I guess the CVV isnt supposed to be needed with a physical card, as you only need it for online/phone payments where you would use the online card details.

    If the CVVs are indeed different, then this feels like you have found possibly one of the very few reasons for needing it and maybe chase didnt plan for that.

    I have the physical card in front of me. There are literally no numbers on it. The only card details available are in the app.
    Even Chase thought the CVV number was printed on the card when I contacted them. Next to the signature strip!
     Im at risk of sounding like a parrot but I suggest you quote the cvv shown under card details on app. That is the cvv number for use with debit card. Every time I've been asked for cvv , that is the number I provide and it is always acceptable.  You obviously disagree ,so I hope you find the elusive cvv elsewhere. Regards

    At the risk of me sounding like a parrot, this doesn't work for me. Perhaps with your card and app there's a coincidence where they are the same? But if you're quoting your card number, where are you getting that from? From your previous posts, I think you're using the number in the app rather the number on the card? If so, I'm not sure you've actually understood my query.
    I consider myself to be a male feminist. Is that allowed?

    In one of my earlier replies I did say that I  may be misinterpting  your query. Hands up, I do not understand your query. All the card details provided on app, are the details I  use whenever necessary and without problem.Not sure what other  numbers you seek.
     Apologies for my misunderstanding.

    Chase have two sets of card details. 

    One is contained in the app and gives you the 16 digit PAN, expiry date and the CVC, and these are used when doing stuff online, or the details you add to Google Pay or Apple Pay. 

    The other set is contained on the card, which have no details printed on them. Most of the details can be found using a card reader but this doesn't produce the CVC.  The two PANs are different but the expiry dates match for me. No idea if the CVC are identical, I doubt it

    The CVV is derived from the PAN + the expiry date, so the CVVs may be identical, but unlikely (there's only 1000 possible values after all).

    There must be a way of working out the CVV, then?

    That's not going to be public knowledge I guess, will be a complicated mathematical logarithm.

    Yes there is, but it requires encryption codes only the bank will have there are lots of calculators (if you have all the info - which no one other than the bank will have)

    I've been able to look up my tap-on tap-off history on a bus company's portal using my Chase details - think I just entered the virtual card details and it showed me the physical details too. Can't quite remember but I definitely managed it.
