I will be travelling to the US in 2-3 days, so I don’t think I will be able to get the physical card. Can transactions be done through the app itself without the card?
Hey @rishita_ghosh! Welcome to our Niyo Community! 
Certainly, you may transact online using Niyo Global virtual card. You can view the virtual card details by logging in to Niyo Global by SBM app > Card Settings > View Details.
