Finu issues Visa cards, but there are several reasons why a merchant might not accept your card:
The merchant may not support Visa payments.
Some payment channels might block Visa transactions for security reasons.
Finu may restrict certain transactions to protect your account.
What you can do:
Check if the merchant accepts Visa cards.
Contact Finu customer support to confirm if there are any restrictions on your account.
Try linking your Finu card to third-party digital wallet services to complete your payment.
