Is there a monthly fee to use a visa card?

Pursuant to the provisions in Article 5 Circular No. 19/2016/TT-NHNN as follows:

Card service fee

....The card issuer collects fees according to its card service fee schedule and is not allowed to collect any additional fees other than the published fee schedule. The card service fee schedule must clearly state the types of fees and fees applicable to each type of card and card service. The card service fee schedule of card issuers must comply with the provisions of law, be publicly posted and must be provided to cardholders before use and when there are changes. Forms of notification and provision of fee information to cardholders must be specifically specified in the card issuance and usage contract. The time from notification to application of fee changes is at least 07 days and must be specifically specified in the card issuance and usage contract...

Thus, collecting card service fees is a matter allowed by law and applied by many banks depending on each bank's different policies. Thus, the question of whether a visa card has a monthly fee depends on the bank's policy and the bank will decide to charge the fee according to the Fee Schedule or waive the fee.
