Is there a transaction fee charged to customers in Hydrogen Debit or Credit?

No.

There are no transaction fees charged to customers for regular usage of the cards. There are some miscellaneous fees listed in the Cardholder Agreement (CHA), such as a fee to replace a physical card that is lost. There is nothing we can do about these one-off charges from the bank or network. Please check the CHA for the most up to date fee schedule.
