I think the card is a no-go. I used to travel, and I would have a two visas, and two mastercards and one or two gas cards. One visa for business expenses, one for personal expenses. I also had a bank card so I could withdraw cash, if I needed some.
Now, suppose I misplace the card. And suppose I misplaced it while on a business trip, around 1000 miles from home. Could I get a hotel room without a card, could I even buy a meal, or rent a car or whatever. And suppose the card is stolen, or I am robbed at gunpoint for the card.
Its a card that does not make offer a backup in the event of a loss. Sorry, this is not for me. It would not be suitable for most travellers. As I traveller, I often use special cards for hotels. This digital wallet is not for me.
