Hi @Alok_Choudhury,
Welcome to the Niyo Community! 
Indian UPI services now work in the UAE. For transactions using your DCB bank account, there are no additional charges for UPI transactions at our end.
You can also use the Scan and Pay feature internationally, with a maximum limit of ₹5,000 per transaction. This limit is combined to both Tap & Pay and Scan & Pay.
If you have any other questions or need further assistance, feel free to reach out!
