I often share many reward and store cards from my Apple Wallet with my partner, And I was wondering if this would be at all possible with virtual cards also?
I have a groceries card that debits from a pot of the same name and I would like to be able to share that card over messages for instance, so she can also use the same card.
Is it not possible to have your card on two devices? 
Never tried personally, but Iâm curious to know.
Yes I have my cards on my iPhone, iPad, Apple Watch and MacBook Pro so could just set it up on a partners device and just approve it using the app but donât know if this would be breaking some T&Cs of Monzo or not?
Iâm not sure it breaks any terms, more a liability aspect and would be difficult to get your money back if youâve permitted someone to use it kinda thing.
Yes, it breaks the Tâs and Câs. They say:
âWhen you add your Monzo card to your device youâre creating a new payment instrument you can use in the same way as your physical Monzo card. Youâre responsible for making sure that nobody else has access to any device which youâve added your Monzo card to. Youâre also responsible for keeping your Monzo card details safe and not sharing them with anyone else. â
Perhaps as an employee of Monzo you shouldnât speculate about stuff like this. Your defence of âviews my ownâ doesnât really work in a legal sense when you have the official Monzo flag next to your name either.
Iâm not representing Monzo in any form, Iâm just expressing personal opinions via an open forum.
Similarly, could say oh I gave X my card to go buy milk from the shop but they purchase a 2 month cruise.
Liability remains with the person who essentially opened themselves to this situation.
What are the potential âlegal implicationsâ of the view expressed? I donât see any.
I can understand their point, and I did say Iâm not sure on the matter, I may work for Monzo but I donât work in, or learn every and all aspects of the business, I donât think itâs possible 
But liability is a key factor here, which was my point.
Go ask your legal dept. and be sure to come back and let us know what they think.
@breville_monkey already pointed to T&Cs so I think thatâs been covered.
As for getting money back, thatâs the ultimate challenge.
Again, what is the actual risk here you think is worth asking them about? I really just canât see what it is you are getting at.
By giving your card to someone Iâm pretty sure youâre also at risk of any fraud claims and T&Cs being waived as mentioned above.
I wouldnât give any family member your card unless they are an official additional card holder which is only possible with credit cards
So. This conversation came up before, and @Dan5 replied saying itâs âokââŚ
So ignore everything else, and trust Dan who works on the fraud team
Some people are just built differently, just take it as that 
If we all followed every rule/T&C, life would be pretty dull.
