OnlyFans does not supports each and every prepaid cards. It only supports Visa prepaid card that has a 3D secure payment system. 3D payment is an advanced security feature that passes data between the merchant, the card issuer, and the cardholder. It reduces the risk of card-not-present fraud and ensures that stolen cards are not used for online purchases.
For every payment you have to verify your payment by providing OTP on your registered phone number. Netspend visa prepaid cards works very well on OnlyFans.
In this way you can use OnlyFans without adding a credit card. Using a prepaid card on OnlyFans can be a good way to confidently make purchases on the site. Currently OnlyFans does not support American Express cards for subscriptions.
