Update August 2017: GTBank Naira Mastercard is now working for Facebook Ads. So as Access bank debit cards. So use this to promote your online businesses and drive traffic to your blog. Its also can be used for transactions on Youtube and Paypal
I was trying to boost a post on facebook using Naira as my preferred currency but it just wasn’t working. I cross-checked severally to make sure I typed my Wema Bank and Ecobank Naira Debit MasterCard details correctly and i did but still my facebook ad page was giving me an error saying ‘invalid card details’.
I also tried other banks like Access Bank, First Bank, Zenith and UBA but still no positive result. This is because Facebook uses DCC(Dynamic Currency Conversion). DCC is responsible for the conversion of dollar amount to naira at CBN rate and that is why you wouldn’t be able to make payments with your naira debit card. I was told to try getting a GT Bank Dollar MasterCard to make purchases from foreign companies like Facebook.
