Will my card issuer charge a fee when paying by credit or debit card?
In some rare cases, some issuing banks charge additional fees from customers who purchase bitcoin using a credit card, for example via Simplex' service. This is because some banks might see purchasing bitcoin as a "money order", a service that incurs additional fees when made with a credit card.
If you would like to know if a cash advance fee will apply to your purchase, you should contact your issuing bank directly beforehand; you can provide them with the code that describes our service: Merchant Category Code (MCC): 6012, 6051 or 6211.
