It might be useful within the app to show the card details. Ideally (from a customer standpoint) to the show everything including card number, expiry date and CVV2 number.
If this isn’t allowed by Mastercard, possibly then just the last 4 digits, so I can tell which one is personal and which is business - they both look the same in Google Pay!
Another alternative which might be useful would be to have full details of a virtual card within the app which the customer can use for online shopping. This could allow you to lock down the physical card to disallow customer not present in case your card is lost or stolen.
Interested to hear what you all think about this!
